                Use of Salt Substitutes To Reduce the Sodium Content in Standardized Foods
                
                    AGENCY:
                    Food and Drug Administration, HHS.
                
                
                    ACTION:
                    Proposed rule.
                
                
                    SUMMARY:
                    The Food and Drug Administration (FDA or we) is proposing to amend our standard of identity (SOI) regulations that specify salt (sodium chloride) as a required or optional ingredient to permit the use of salt substitutes in standardized foods, to reduce the sodium content. Reducing sodium may help reduce the risk of hypertension, a leading cause of heart disease and stroke. The proposed rule, if finalized, would help support a healthier food supply by providing flexibility to facilitate industry innovation in the production of standardized foods lower in sodium while maintaining the basic nature and essential characteristics of the foods.

                I. Executive Summary
                A. Purpose of the Proposed Rule
                This proposed rule, if finalized, would amend FDA's definitions and standards of identity (SOI; the acronym is used to refer to both the singular standard of identity and the plural standards of identity) that specify salt (sodium chloride) as a required or optional ingredient. Foods for which FDA has established a SOI are referred to as standardized foods. The amendments would permit the use of safe and suitable salt substitutes to replace some or all of the salt used in the manufacture of standardized foods. The proposed rule would not list specific salt substitutes; instead, the proposed rule would cover ingredients or combinations of ingredients used as salt substitutes by food manufacturers currently or in the future. If finalized, the proposed rule would support efforts to reduce sodium content in standardized foods and may help to improve consumer dietary patterns by reducing sodium consumption. On average Americans consume 50% more sodium than the recommended limit for those aged 14 and older (Ref. 1). Reducing sodium consumption may help reduce the risk of hypertension, a leading cause of heart disease and stroke. The proposed rule would allow food manufacturers the flexibility to use salt substitutes and allow for innovation in producing healthier standardized foods. The proposed rule would promote honesty and fair dealing in the interest of consumers by accommodating their preferences for lower sodium varieties of foods. This, in turn, would make lower-sodium options available to them.
                B. Summary of the Major Provisions of the Proposed Rule
                FDA is proposing to amend its SOI that specify salt as a required or optional ingredient to permit the use of safe and suitable salt substitutes in standardized foods, to reduce the sodium content. We propose to amend our regulation entitled Food Standards: General (21 CFR part 130) to create a new subpart C entitled Flexibility in Standardized Foods and add a new section entitled Ingredient Flexibility in Standardized Foods to define salt substitute. We also propose to amend 80 SOI to permit salt substitutes.
                We also propose to update the incorporation by reference (IBR) information of several SOI to refer to the most recent versions of the IBR materials and to provide up-to-date contact information for obtaining the IBR materials. For example, the proposed rule would update the referenced methods of analysis to those in the Official Methods of Analysis of AOAC INTERNATIONAL, 21st Ed. 2019. We also propose to make technical amendments to correct inconsistencies and typographical errors in some SOI regulations.
                We tentatively conclude that the proposed amendments are necessary to modernize SOI to provide flexibility and facilitate innovation in the production of standardized foods with less sodium, and to promote honesty and fair dealing in the interest of consumers.
                C. Legal Authority
                
                    We are proposing this rule consistent with our authority in sections 201, 401, 402, 409, and 701 of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 321, 341, 342, 348, 371). We 
                    
                    discuss our legal authority in greater detail in section IV.
                
                D. Costs and Benefits
                The proposed rule would amend SOI that specify salt as a required or optional ingredient, to permit the use of salt substitutes. The proposed rule would give manufacturers the flexibility to use salt substitutes in standardized foods, to reduce sodium content. If finalized, the proposed rule would not result in regulatory costs for firms. The proposal would not require manufacturers to replace salt with salt substitutes. Instead, manufacturers would have the option of using salt substitutes to replace salt in standardized foods. Should manufacturers choose to use this flexibility to reformulate some products by substituting some salt with salt substitutes, the primary benefits realized would result from lower sodium consumption by U.S. consumers who choose to purchase and consume the reformulated versions of such products, and increased profit (producer surplus) for manufacturers (or at least no decrease in profits). The primary cost of such voluntary market behavior would include reformulation and relabeling costs for the manufacturers.

                III. Background
                A. Introduction
                As a public health agency, FDA seeks to improve dietary patterns in the United States to help reduce the burden of diet-related chronic diseases and advance health equity as nutrition-related chronic diseases are experienced disproportionately by certain racial and ethnic minority groups, those living in rural communities, and those with lower socioeconomic status. We are committed to accomplishing this, in part, by creating a healthier food supply for all. One way FDA is working towards this goal is by helping to reduce sodium across the food supply.
                Americans consume, on average, 3,400 milligrams of sodium per day (mg/day) (Ref. 1). This is nearly 50 percent more than the sodium Chronic Disease Risk Reduction Intake (CDRR) established by the National Academies of Sciences, Engineering and Medicine, which sets the limit for sodium for individuals 14 years and older at 2,300 mg/day. This CDRR was adopted as a recommendation by the Dietary Guidelines for Americans, 20202025 (Refs. 1 and 2). Reducing sodium intake to below the CDRR level is expected to help reduce the risk of chronic disease. Excess sodium intake increases risk for hypertension, commonly referred to as high blood pressure, a leading cause of heart disease and stroke and the first and fifth leading cause of mortality in 2020 in the United States (Refs. 26). Decreasing sodium intake is, therefore, expected to reduce the rate of hypertension. It has been estimated that sufficient reductions in the population average sodium intake could potentially result in tens of thousands fewer cases of heart disease and stroke and associated mortality each year (Refs. 79).
                Reducing sodium in processed, packaged and prepared foods will help create a healthier food supply. A healthier food supply has the potential to contribute to better health outcomes and reduce preventable death and disease related to poor nutrition; many of which are experienced at higher rates by certain racial and ethnic groups (Ref. 10). For example, more than 4 in 10 American adults have hypertension and that number increases to nearly 6 in 10 for non-Hispanic Black Americans (Ref. 11). African American women are almost 60 percent more likely to have hypertension when compared to non-Hispanic white women, and African American adults are 30% more likely than non-Hispanic white Americans to die from coronary heart disease (CHD) (Refs. 12 and 13); further, American Indians/Alaskan Natives are 50% more like to be diagnosed with CHD than non-Hispanic Whites (Ref. 13). The proposed rule's likely effect on increasing the availability of lower sodium products may contribute to government-wide efforts to reduce health disparities.
                Reducing sodium in processed, packaged and prepared food is a critical step in helping to improve consumer dietary patterns. More than 70 percent of sodium consumed in the United States comes from sodium added during manufacturing and commercial food preparation (Ref. 14). This makes it challenging for consumers to reduce their sodium consumption. Further, because salt (sodium chloride) serves various functions in processed, packaged, and prepared foods, industry must balance sodium reduction efforts while manufacturing products that maintain the properties of a certain food and still meet the preferences of consumers.
                FDA is engaged in several efforts aimed at encouraging gradual, efficient reduction of overall sodium content in processed, packaged and prepared food products. We recently issued two guidance documents for industry to support voluntary industry efforts to reduce sodium in the food supply and facilitate industry innovation toward creating healthier foods. The December 2020 guidance for industry entitled The Use of an Alternate Name for Potassium Chloride in Food Labeling (Potassium Chloride guidance) (Ref. 15) sets forth FDA's enforcement discretion policy with respect to declaring potassium chloride as potassium salt in the ingredient statement in the labeling of food products. In October 2021, we issued guidance for industry entitled Voluntary Sodium Reduction Goals: Target Mean and Upper Bound Concentrations for Sodium in Commercially Processed, Packaged, and Prepared Foods (Voluntary Sodium Reduction Goals guidance) (Ref. 16). The guidance document finalizes the short-term (2.5 year) voluntary sodium reduction targets in over 160 categories of packaged and restaurant prepared food. These short-term targets are based on a reduction of average sodium intake from current levels of 3,400 mg/day to 3,000 mg/day, and they serve as initial benchmarks for a broad and gradual reduction of sodium in the food supply (Ref. 16 and 17). Through the two guidance documents and this rulemaking, our intent is to support the gradual reduction of sodium across the food supply.
                
                    Under our authority in section 401 of the FD&C Act, FDA establishes SOI to promote honesty and fair dealing in the interest of consumers. SOI are established under the common or usual name of a food. Such foods are said to be standardized. SOI define the food and typically provide the types of ingredients that it must contain (
                    i.e.,
                     mandatory ingredients) and that it may contain (
                    i.e.,
                     optional ingredients). They sometimes specify the amount or proportion of each ingredient. Many SOI also designate methods of production. We have over 250 SOI for a wide variety of food products.
                    
                
                B. Need for the Regulation
                Salt substitutes are ingredients that can help reduce sodium in processed, packaged and prepared foods. Food manufacturers wishing to reduce salt in their products to accommodate consumer preferences or for other reasons sometimes use substitute ingredients that provide similar taste and other technical functions of salt in foods. Most of our SOI that include salt as a required or optional ingredient do not permit the use of salt substitutes. Therefore, food manufacturers are currently precluded from using salt substitutes in the production of these standardized foods. However, manufacturers may use salt substitutes in the production of non-standardized foods. Various stakeholders have expressed concern that many SOI are out of date and may impede innovation, including the ability to produce healthier foods (Ref. 18). Manufacturers seeking to reduce sodium in standardized foods are limited because they are unable to produce foods using salt substitutes and still conform to the SOI. In this way, the SOI may become a barrier to innovation.
                Permitting the use of salt substitutes is aligned with FDA's goal to reduce sodium across the food supply and our work to reduce sodium consumption. Research suggests that consumers usually do not notice small reductions in sodium and, over time, consumer palates adjust to lower sodium levels (Ref. 19). Through our work on the Voluntary Sodium Reduction Goals guidance and the Potassium Chloride guidance, we learned that stakeholders, including industry, consumers, consumer advocacy, scientific and professional health organizations, generally support allowing the use of salt substitutes. In another public engagement, some stakeholders discussed modernizing SOI to allow the use of salt substitutes using a horizontal approach (Ref. 18). A horizontal approach to amending standards is a change that could be made across all, or broad categories of SOI to provide flexibility and facilitate innovation in the production of more nutritious foods. We considered several options for permitting salt substitutes in standardized foods and evaluated how to apply this change across multiple SOI. The proposed rule, if finalized, would adopt a horizontal approach to amending the applicable SOI. The proposed rule would permit the use of salt substitutes in SOI that specify salt as a required or optional ingredient, to reduce sodium in the food. Because the use of salt substitutes in these SOI is currently precluded, any use of salt substitutes by manufacturers under the rule would contribute to reduced sodium intake to some degree.
                Permitting the use of salt substitutes in standardized foods would contribute to our goal to reduce sodium across the food supply. It would facilitate voluntary industry efforts toward sodium reduction by providing flexibility and supporting innovation in the production of healthier standardized foods, which may help some consumers to gradually reduce the sodium in their diet and contribute to better health outcomes. The proposed rule may have the potential to contribute to government-wide efforts to reduce health disparities if the use of salt substitutes helps populations disproportionately affected by hypertension to consume less sodium.
                C. FDA's Current Regulatory Framework
                The FD&C Act gives us the authority to establish definitions and standards for foods with respect to identity, quality, and fill of container (21 U.S.C. 341). SOI specify the permitted ingredients, both mandatory and optional, and sometimes describe the amount or proportion of each ingredient. Many SOI also prescribe a method of production or formulation. Foods for which FDA has established a SOI must conform to the applicable definition and standard. A food is misbranded if it purports to be or is represented as a food for which a SOI has been established but fails to conform to the definition and standard (21 U.S.C. 343(g)).
                
                    SOI are codified in parts 130 to 169 (21 CFR parts 130 to 169). Part 130 outlines general provisions, including the use of food additives in food standards. Part 130 also includes the general definition and SOI (
                    i.e.,
                      130.10). Parts 131 to 169 set forward SOI for foods in 21 food product categories.
                
                We have long interpreted the term salt in the food standards in parts 131 to 169 to refer to sodium chloride. Salt is specified as a required or optional ingredient in 80 SOI across these parts. Some SOI cross reference other SOI. For example, in part 136 (21 CFR part 136), salt is an optional ingredient in the SOI for bread, rolls, and buns ( 136.110) which is referenced in several other SOI, including: enriched bread, rolls, and buns ( 136.115), milk bread, rolls, and buns ( 136.130), raisin bread, rolls, and buns ( 136.160), and whole wheat bread, rolls, and buns ( 136.180). The result of such cross referencing is that salt is a required or an optional ingredient in 140 SOI.
                Manufacturers of standardized foods have few options for reducing the sodium content of their products. If salt is a required ingredient, they may generally use less salt. If salt is an optional ingredient, they may either use no salt or less salt. However, they cannot replace salt with another ingredient unless the standard permits the use of another ingredient. Most SOI do not provide for a substitute for salt. In some instances, we established separate SOI for low sodium foods, thereby allowing manufacturers to reduce the amount of salt used and to substitute other ingredients. Manufacturers may also modify the sodium content of standardized foods under the general definition and SOI in  130.10 (Requirements for foods named by use of a nutrient content claim and a standardized item), provided that certain conditions are met.
                
                    Deviation from a SOI is permitted under the general definition and SOI in  130.10. The deviation must be due to a modification described by an expressed nutrient content claim defined by regulation. Expressed nutrient content claims for the sodium content of foods (
                    e.g.,
                     low sodium) are provided under  101.61 (21 CFR 101.61) (Nutrient content claims for the sodium content of foods). Thus, sodium modifications to a standardized food are permitted if the modification meets the requirements for a nutrient content claim under  101.61. The modified food becomes a new standardized food under  130.10 and is named with the nutrient content claim and the name of the standardized food from which it deviates (
                    e.g.,
                     low sodium provolone cheese). It may be impracticable for manufacturers to reduce the sodium content in standardized foods to the extent required by a nutrient content claim. For example, to meet the requirements for a reduced sodium nutrient content claim, manufacturers must decrease the sodium in the food by at least 25 percent. Certain foods do not retain the same characteristics when the amount of sodium is reduced to this degree, and therefore, the general definition and SOI does not facilitate the production of lower sodium varieties. This proposed rule would allow manufacturers to reduce the sodium in standardized foods in amounts less than the amounts prescribed in  101.61. This would provide manufacturers greater flexibility when reformulating standardized foods to lower the sodium content.
                
                
                    Presently, three SOI specifically permit the use of a salt substitute. The SOI for low sodium cheddar cheese ( 133.116) and low sodium colby 
                    
                    cheese ( 133.121) permit the use of a salt substitute. The SOI for low sodium colby cheese prohibits the use of salt and permits the use of a salt substitute that contains no sodium ( 133.121(a)). The SOI for margarine ( 166.110) specifically permits the use of potassium chloride in the manufacture of dietary margarine. Potassium chloride, in some instances, can be used as a partial substitute for sodium chloride in food processing and manufacturing.
                
                If finalized, the proposed rule would provide a new means for manufacturers to reduce the sodium content of standardized foods. Salt substitutes would be permitted in any food for which an SOI has been established and that specifies salt as a required or an optional ingredient. This would be achieved without requiring the minimum reductions in sodium content under  101.61 and renaming of food products as is required for modifications under  130.10.
                IV. Legal Authority
                We are issuing this proposed rule consistent with our authority in sections 201, 401, 402, 409, and 701of the FD&C Act. Section 401 of the FD&C Act directs the Secretary of Health and Human Services (Secretary) to issue regulations fixing and establishing for any food a reasonable definition and standard of identity, standard of quality, or standard of fill of container, whenever in the judgment of the Secretary, such action will promote honesty and fair dealing in the interest of consumers. We tentatively conclude that permitting the use of salt substitutes to replace some or all of the salt used in the production of standardized foods would promote honesty and fair dealing in the interest of consumers. Consumers desire more nutritious and healthy food options, such as lower sodium versions of foods. This proposed rule, if finalized, would allow for industry development and sale of such foods while ensuring that standardized foods meet consumer expectations and preferences with respect to lower-sodium varieties.
                FDA has codified food standards in parts 130 to 169. These regulations do not provide either an authorization or exemption from regulation as a food additive under section 409 of the FD&C Act. The FD&C Act defines food additive, in relevant part, as any substance, the intended use of which results or may reasonably be expected to result, directly or indirectly, in its becoming a component of food, if such substance is not generally recognized by experts as safe under the conditions of its intended use (section 201(s) of the FD&C Act). The definition of food additive exempts any uses that are the subject of prior sanction (section 201(s)(4) of the FD&C Act)). Food additives are deemed unsafe except to the extent that FDA approves their use (section 409(a) of the FD&C Act). Food is adulterated when it contains an unapproved food additive (section 402(a)(2)(C) of the FD&C Act).
                
                    We also are issuing this proposed rule under section 701(a) of the FD&C Act, which authorizes FDA to issue regulations for the efficient enforcement of the FD&C Act. Regulations issued under section 701(a) must effectuate a congressional objective expressed elsewhere in the Act (
                    Association of American Physicians and Surgeons, Inc.
                     v. 
                    FDA,
                     226 F. Supp. 2d 204 (D.D.C. 2002) (citing 
                    Pharm. Mfrs. Ass'n.
                     v. 
                    FDA,
                     484 F. Supp. 1179, 1183 (D. Del. 1980))). Amending SOI to permit the use of salt substitutes would effectuate the congressional objective to promote honesty and fair dealing in the interest of consumers expressed in section 401 of the FD&C Act. Permitting salt substitutes in standardized foods under this rule may help provide more options to consumers while ensuring that the foods maintain their basic nature and essential characteristics. The proposed amendments to the SOI for dairy products under parts 131, 133, and 135 are issued under section 701(e) of the FD&C Act.  
                
                V. Description of the Proposed Rule
                The proposed rule, if finalized, would:
                 Amend part 130 to add a new subpart C entitled Flexibility in Standardized Foods.
                 Add a new  130.30 to provide for Ingredient Flexibility in Standardized Foods and define salt substitute as a safe and suitable ingredient (or combination of ingredients) that is used to replace some or all of the added salt (sodium chloride), to reduce sodium in the food, and that serves the functions of salt in the food.
                 Amend the 80 SOI that specify salt as a required or an optional ingredient to add regulatory text to permit the use of salt substitute, as defined in proposed  130.30.
                 Update the IBR information of several SOI to refer to the most recent versions of the IBR materials and to provide up-to-date contact information for obtaining the IBR materials. The proposed rule would also update the referenced methods of analysis to those in the Official Methods of Analysis of AOAC INTERNATIONAL, 21st Ed. 2019.
                 Make technical amendments to correct inconsistencies and typographical errors in some SOI regulations.
                A. Scope/Applicability
                The proposed rule, if finalized, would amend SOI in parts 131 to 169. Specifically, the proposed rule would permit the use of salt substitutes in the foods covered by 80 SOI that include salt as a required or an optional ingredient. The proposal would also permit the use of salt substitutes in foods covered by SOI that reference some of the 80 SOI.
                This rule does not propose to amend the SOI for oysters ( 161.130). The SOI in  161.130 provides for the optional use of salt water in the shucking of oysters. We understand that it is not standard industry practice to constitute a salt and water solution for this process. Rather, seawater accessible at the processing location is collected and used in the shucking process. Because salt is not an ingredient added by the manufacturer, we are not proposing to amend this SOI. We request comments on this approach and our understanding of current industry practice.
                B. The Basic Nature and Essential Characteristics of a Standardized Food
                
                    Proposed  130.30(b) would require that ingredients used as salt substitutes do not change the basic nature and essential characteristics of the standardized food. FDA previously discussed its understanding about the basic nature of a food in a proposed rule entitled Food Standards; General Principles and Food Standards Modernization, (70 FR 29214, May 20, 2005). The basic nature of a food is generally what the food is. It concerns the general attributes of the product. For example, the basic nature of a particular type of cheese is that it is a milk-derived food of a certain form and consistency. The essential characteristics of a food may contribute to achieving the basic nature of the food, but consumers may not be aware of the essential characteristics. The essential characteristics of a food are those that distinguish a food. Foods may be distinguished by their ingredients, compositional characteristics, physical characteristics, or levels of certain nutrients or the way they are producedall of which are the essential characteristics of the food. For example, the essential characteristics of a particular type of cheese may include the bacterial culture used, the processing method, or the fat and moisture content that contribute to the unique characteristics of that cheese.
                    
                
                Use of salt substitutes that do not change the basic nature and essential characteristics of the standardized food under this proposed rule is necessary to ensure the availability of foods that promote honesty and fair dealing in the interest of consumers, in accordance with section 401 of the FD&C Act.
                C. Definition of Salt Substitute
                Under the FD&C Act, any substance that is intentionally added to food is a food additive that is subject to premarket review and approval by FDA unless that substance is excluded from the definition of a food additive. These excluded food substances include substances that are generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use (generally recognized as safe or GRAS), or the substances are prior sanctioned and excepted from the definition of a food additive. FDA considers salt a common food ingredient that is GRAS for its intended use (21 CFR 182.1(a)). A salt substitute that is added to a standardized food, to replace some or all of the salt, must be an approved food additive or GRAS for its intended use. For example, potassium chloride is a GRAS substance (21 CFR 184.1622).
                The proposed rule would amend  130.30(c)(1) to define salt substitute as a safe and suitable ingredient (see  130.3(d)) or combination of ingredients that is used to replace some or all of the added salt (sodium chloride), to reduce the sodium in the food, and that serves the functions of salt in the food. We are proposing to define salt substitute broadly to provide flexibility and facilitate innovation in the future without the need for additional rulemaking. Thus, the proposed rule would not list specific salt substitutes; instead, the proposed rule would cover ingredients or combinations of ingredients currently used as salt substitutes and ingredients or combinations of ingredients that may be used as salt substitutes in the future, as a result of advances in food science and technological changes.
                Salt is a required or optional ingredient in a wide range of standardized foods. The proposed rule also would allow manufacturers the flexibility to explore new ways to replace salt and reduce the sodium content of standardized foods while preserving the basic nature and essential characteristics of the food.
                We recognize that salt serves various functions in standardized foods. For example, depending on the food, salt may be important for taste, microbial safety, and other functions. The proposed definition would require that the salt substitute be used to replace some or all of the added salt, to reduce the sodium in the food, and serve the functions of salt in the food. This would ensure that the salt substitute performs a similar function to salt in the standardized food, while helping to reduce the sodium content. The extent to which salt can be replaced depends on the ability of the salt substitute to replicate the functions of salt in the food without compromising the food's safety and nutritional quality. The proposed rule would not establish a minimum replacement level for salt. It would not prescribe the sodium content of the foods or any parameters pertaining to the production of the food. Manufacturers would determine the level of salt replacement appropriate for the particular standardized food.
                Our intent is to provide manufacturers flexibility and facilitate sodium reduction across the food supply while not changing the basic nature and essential characteristics or adversely affecting the nutritional quality and safety of standardized foods. To accomplish this, proposed  130.30(c)(1) would limit the definition of salt substitute and therefore the use of salt substitutes to an ingredient or a combination of ingredients that serve the functions that salt served in the particular standardized food. The ingredient or combination of ingredients may include substances intended to mitigate the impact of removing salt and are needed to maintain the basic nature and essential characteristics of the food.
                
                    Some manufacturers are currently using salt substitutes to reduce sodium in foods in the marketplace. Scientific articles and reports have used several examples of salt substitutes when discussing sodium reduction efforts (Ref. 19, 20, 21). The use of potassium chloride is one example of a safe and suitable ingredient discussed in the scientific literature that, in some instances, serves as a partial substitute for sodium chloride in food processing and manufacturing (Ref. 15). Other examples of ingredients listed in the scientific literature include herbs and spices, yeast extracts, monosodium glutamate, amino acids, and dairy extracts (Ref. 19). The food industry is pursuing sodium reduction efforts, including the use of salt substitutes (
                    e.g.,
                     in products marketed as low or reduced sodium), in a variety of foods, including in canned fish and soups (Ref. 21). We request data and information on the types of salt substitutes currently being used in the U.S. market to support sodium reduction and on potential salt substitutes that may be used as a result of the new flexibility provided in this proposed rule.
                
                D. Amending Standard of Identity Regulations to Permit Salt Substitutes
                We propose to amend our regulations to permit the use of salt substitutes in SOI that specify salt as a required or an optional ingredient. Foods for which FDA has established a SOI must conform to the applicable standard. Consequently, without these amendments, most standardized foods cannot be modified to replace salt with salt substitutes unless salt can be reduced in sufficient quantity to meet a nutrient content claim under  101.61 (see section III.C). As stated previously, amending 80 applicable SOI to permit the use of salt substitutes is necessary to give manufacturers the most flexibility to use salt substitutes in standardized foods. The proposed rule would permit the use of salt, salt substitute or a combination of the two in applicable standardized foods. Salt substitutes used would be declared on the label in accordance with section 403(i)(2) of the FD&C Act.
                Where salt is permitted in our SOI, the use is not described uniformly in the provisions of the standards. This is largely due to the standards having been established with different structural formats. The lack of uniformity is also due to the use of salt differing across different standardized foods. In some foods, salt is a mandatory ingredient, and in other foods, salt is an optional ingredient. For some foods, salt is permitted at a specific point in the manufacturing process, whereas salt is permitted in other foods without regard to manufacturing time. These differences mean that different amendatory language in the individual standards is necessary to permit the use of salt substitutes. To address this, we propose four types of revisions to the current regulatory text in the applicable SOI.
                In particular, there are differences in how the use of salt is prescribed in certain SOI for cheeses and related cheese products in part 133 (21 CFR part 133). For example, several SOI for cheeses use terms such as salted, salting, brine, or salt solution, to prescribe the application of salt in the cheesemaking process. For additional clarity, the proposed amendments for cheeses and related cheese products are grouped and discussed separately from other SOI.
                
                    There are 4 types of revisions to the applicable SOI in this proposed rule. 
                    
                    The third and fourth types only apply to SOI in part 133.
                
                 Type 1: When the current text of the SOI lists salt as an optional ingredient, the proposed rule would amend the SOI to state, salt or salt substitute.
                 Type 2: When the current text of the SOI provides for the use of salt in a paragraph, the proposed rule would amend the SOI to state, salt or salt substitute.
                 Type 3: When the current text of the SOI uses terms such as salted, salted with dry salt or brine, or salting, to provide for use of salt in the food, but does not specify salt as an ingredient, the proposed rule would amend the optional ingredient list to add salt substitute.
                 Type 4: When the current text of the SOI uses terms such as salted, or salted in brine, to provide for the use of salt in the food, but does not provide a list of optional ingredients, the proposed rule would amend the SOI to add a paragraph stating that, During the cheesemaking process, where the curd is salted, salt substitute may be used.
                We summarize these changes in tables 1 and 2.
                1. Amendments to SOI not in Part 133
                We propose amendments to permit the use of salt substitutes in 39 SOI for products that are not cheeses or related cheese products prescribed in part 133. The amendments would occur through two types of revisions to the current regulatory text of the applicable SOI.
                
                    a. Type 1 revision for SOI not in part 133.
                     Several SOI provide for the addition of salt by listing it as an ingredient (
                    e.g.,
                     as an optional ingredient, other optional ingredient, or including salt in a list of substances that could be added as a seasoning or flavoring.) We propose to amend these SOI to permit the addition of a salt substitute in addition to, or in place of, salt by replacing salt with salt or salt substitute. For example, the SOI for acidified milk ( 131.111(e)(8)) lists salt under other optional ingredients; the proposed rule would replace salt with salt or salt substitute. As another example, the SOI for canned tuna (21 CFR 161.190) includes salt in a list of seasoning or flavoring ingredients ( 161.190 (a)(6)(i)); the proposed rule would replace salt with salt or salt substitute.
                
                
                    b. Type 2 revision for SOI not in part 133.
                     Five SOI prescribe the use of salt in paragraphs that describe the food, rather than as part of an ingredient list. We propose to amend these SOI to permit the addition of a salt substitute in addition to, or in place of, salt by replacing salt with salt or salt substitute in the regulatory text. For example, the SOI for catsup (21 CFR 155.194) specifies the optional use of salt by stating, [t]he food may contain salt; and the SOI for self-rising flour (21 CFR 137.180) specifies that the food is seasoned with salt. In both examples, we propose to replace salt with salt or salt substitute.
                
                Table 1 summarizes the amendments to the SOI for foods other than cheeses and related cheese products. We request comment on whether there would be safety concerns, technical infeasibilities, or other issues that would prevent the use of a salt substitute in any SOI listed in table 1.

                2. Amendments to SOI in Part 133
                Type 1 and type 2 amendments are also proposed for certain SOI for cheeses and related cheese products. We propose type 3 and type 4 amendments for the several SOI in part 133 that specify salt as an ingredient, using terms such as brine, salt brine, salt solution, salted, and salting. Brine, salt brine, and salt solution are solutions containing sodium chloride and salted and salting in the manufacture of cheese refer to the use of sodium chloride. The proposed rule would provide manufacturers of standardized cheeses and related cheese products, the flexibility to use salt substitutes to replace some or all of the salt prescribed in these processes.
                We propose to permit the use of salt substitutes in 41 SOI for cheeses and related cheese products. Some SOI in part 133 list salt under optional ingredients or other optional ingredients, while others vary in how they prescribe the use of salt in the paragraph that describes the cheese or cheesemaking process. Because of these differences, we propose four types of revisions to the current regulatory text of the applicable SOI for cheeses and related cheese products.
                
                    a. Type 1 revision for SOI in part 133.
                     Several SOI for cheeses and related cheese products provide for the addition of salt by listing it as an ingredient (
                    e.g.,
                     as an optional ingredient or other optional ingredient.) We propose to amend these SOI to permit the addition of salt substitute in addition to, or in place of, salt by replacing salt in the list with salt or salt substitute. For example, the SOI for cold-pack and club cheese lists salt under optional ingredients ( 133.123(c)(3)). The proposed rule would replace salt with salt or salt substitute.
                
                
                    b. Type 2 revision for SOI in part 133.
                     Five SOI provide for the use of salt in paragraphs that describe the cheese, rather than as part of an ingredient list. We propose to amend these SOI to permit the addition of a salt substitute in addition to, or in place of, salt by replacing salt in the paragraphs with salt or salt substitute. For example, the proposed rule would replace salt with salt or salt substitute in three paragraphs of the SOI for dry curd cottage cheese ( 133.129(b)(1)(i) through (iii)) and in one paragraph of the SOI for sap sago cheese ( 133.186 (a)(2)).
                
                
                    c. Type 3 revision for SOI in part 133.
                     Some SOI for cheeses and related cheese products provide for the use of salt in a paragraph that describes the cheesemaking process, through terms such as salted, salted with dry salt or brine, or salting, and do not specify salt in a list of ingredients (
                    e.g.,
                     as an other optional ingredient). We propose to amend these SOI to permit the addition of a salt substitute in addition to, or in place of, salt by adding salt substitute as a new subparagraph in the current list of other optional ingredients. For example, the SOI for cheddar cheese ( 133.113(a)(3)) states that the curd is salted, stirred, further drained, and pressed into forms, but does not list salt in the optional ingredients in  133.113(b)(3). The proposed rule would amend  133.113(b)(3) by adding a new subparagraph, salt substitute (proposed  133.113(b)(3)(vi)).
                
                
                    d. Type 4 revision for SOI in part 133.
                     Several SOI for cheeses and related cheese products provide for the use of salt in a paragraph that describes the cheesemaking process through terms such as salted or salted in brine, but do not include a list of ingredients (
                    e.g.,
                     optional ingredient or other optional ingredient) that could be amended to add salt substitute. We propose to amend these SOI to explicitly permit the use of a salt substitute in the cheesemaking process. For example, the SOI for asiago fresh and asiago soft cheese ( 133.102(b)) provides that the curd is salted in brine and cured in a well-ventilated room, but does not have an optional ingredient list. The proposed rule would amend this SOI by adding a new subparagraph at  133.102(c)(3) to state, During the cheesemaking process, where the curd is salted, salt substitute may be used.
                
                Table 2 summarizes the amendments to the SOI for cheeses and related cheese products. We request comment on whether there would be safety concerns, technical infeasibilities, or other issues that would prevent the use of salt substitute in any SOI listed in table 2.

                E. Update Incorporation by Reference
                Several of the 80 SOI that specify salt as a required or optional ingredient contain outdated references. We propose to update the IBR paragraphs in these SOI to refer to the most recent versions of the IBR materials and to provide up-to-date contact information for obtaining the IBR materials. We propose to add IBR paragraphs to subparts A of parts 131, 137, 139, 150, 155, and 161. SOI in subparts B of these parts would reference applicable IBR paragraphs in subpart A. We also propose to update the IBR paragraphs in the SOI under parts 136, 145, and 166 which would not have IBR paragraphs in subparts A of these parts. The revised format is for administrative efficiency. Specifically, the proposed rule would update the IBR information for  131.111, 131.112, 131.160, 131.162, 131.170, 136.110, 137.180, 137.270, 139.110, 139.150, 145.110, 150.110, 155.120, 155.130, 155.170, 161.145, 161.173,161.190, and 166.110. These SOI list methods of analysis that are from the 13th or 15th editions of Official Methods of Analysis of the Association of Official Analytical Chemists. Additionally,  155.170 lists an incorrect section number for the method for alcohol insoluble solids in canned peas. We propose to update the referenced methods of analysis to those in the Official Methods of Analysis of AOAC INTERNATIONAL, 21st Ed. 2019. These proposed changes will ensure that the reference materials are current, accessible, and meet Federal requirements pertaining to IBR (see 1 CFR part 51).

                F. Technical Amendments
                We also propose to make technical amendments to correct inconsistencies and typographical errors in several of the 80 SOI regulations that specify salt as a required or optional ingredient. The corrections are non-substantive. The proposed rule would:
                 Amend  133.118(c)(2) to replace 143 with 145.
                 Amend  133.150(c)(2) to replace 143 with 145.
                 Amend  133.150(e)(1) to replace unusual with usual.
                
                     Amend  133.182(c)(2) to replace 143 with 145.
                    
                
                 Amend  133.184(b) to replace Operational with Optional.
                 Amend  133.186(c) to replace Nonmenclature with Nomenclature.
                 Amend  133.187(c)(2) to replace 143 with 145.
                 Amend  133.188(c)(2) to replace 143 with 145.
                 Amend  155.170(b)(1)(iii) to replace shrivelled with shriveled.
                 Amend  158.170(b)(1)(iii) to replace shrivelled with shriveled.
                 Amend  168.140(a) to replace mapel with maple.
                VI. Proposed Effective/Compliance Dates
                
                    We propose that any final rule resulting from this rulemaking be effective 30 days after the final rule's date of publication in the 
                    Federal Register
                     insofar as it amends non-dairy SOI. We believe that this effective date is appropriate because it will provide industry the flexibility to use salt substitutes to reduce the sodium content in standardized foods. Some manufacturers are already exploring ways to reduce sodium in standardized foods, and this proposed rule, if finalized, will assist in those efforts. For the same reasons, FDA proposes that any dairy SOI that may be amended based on this proposal, unless stayed by the filing of proper objections, will also be effective 30 days after the final rule's date of publication in the 
                    Federal Register
                    .
                
                VII. Preliminary Economic Analysis of Impacts
                
                    We have examined the impacts of the proposed rule under Executive Order 12866, Executive Order 13563, the Regulatory Flexibility Act (5 U.S.C. 601612), and the Unfunded Mandates Reform Act of 1995 (Pub. L. 1044). Executive Orders 12866 and 13563 direct us to assess all costs and benefits of available regulatory alternatives and, when regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity). The Office of Information and Regulatory Affairs has determined that this proposed rule is a significant regulatory action as defined by Executive Order 12866 Section 3(f)(1).
                    1
                    
                
                
                    
                        1
                         We note that this Executive Order 12866 applies only to the non-dairy SOI portions of this rulemaking; the dairy SOI covered by this rulemaking are regulations or rules issued in accordance with the formal rulemaking provisions of 5 U.S.C. 556, 557 (see 21 U.S.C. 701(e)(1)) and therefore excluded by section (d)(1) of Executive Order (E.O.) 12866.
                    
                
                  
                The Regulatory Flexibility Act requires us to analyze regulatory options that would minimize any significant impact of a rule on small entities. We do not anticipate the proposed rule would generate regulatory impacts on small entities. As with any voluntary market behavior, larger firms may have certain advantages over small firms in some areas, while smaller firms may have advantages in other areas. As a result, we propose to certify that the proposed rule will not have a significant economic impact on a substantial number of small entities.
                The Unfunded Mandates Reform Act of 1995 (section 202(a)) requires us to prepare a written statement, which includes an assessment of anticipated costs and benefits, before proposing any rule that includes any Federal mandate that may result in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100,000,000 or more (adjusted annually for inflation) in any one year. The current threshold after adjustment for inflation is $165 million, using the most current (2021) Implicit Price Deflator for the Gross Domestic Product. The proposed rule would not result in a mandated expenditure in any year that meets or exceeds this amount.
                
                    The proposed rule would permit, but not require, manufacturers to use salt substitutes to replace salt where salt is a required or optional ingredient in standardized foods. If finalized, the benefits of this rule would be additional flexibility in the manufacture of standardized foods and the potential for reduced salt consumption by consumers which may contribute to better health outcomes. We have no information to suggest the use of currently available salt substitutes would lead to improved product characteristics (
                    e.g.,
                     shelf life) or would lead to reduced production costs and potentially lower prices. We request comment on such potential benefits of reformulation for manufacturers and on how many standardized foods manufacturers might choose to reformulate, either in the relatively near or longer-run future.
                
                
                    The proposed rule, if finalized, would not impose requirements resulting in regulatory costs on firms or consumers. Manufacturers would have the 
                    option
                     of using salt substitutes. There are no regulatory implications for not reading the rule or deciding not to use salt substitutes. Should manufacturers choose to use this flexibility to reformulate some products by substituting some salt with salt substitutes, the primary benefits realized would result from lower sodium consumption on average by U.S. consumers, assuming they choose to purchase and consume the reformulated versions of such products, and increased profit (producer surplus) for manufacturers, assuming they find offering reformulated versions of such products consistent with maximizing firm profits. The primary costs of such voluntary market behavior would be reformulation and relabeling costs for manufacturers. We currently lack data to estimate any net social benefits from voluntary market behavior relating to future use of salt substitutes made possible by this rule, but cite some published analyses below related to meeting voluntary sodium reduction targets that could partially be addressed via the flexibility provided by this rule. We request public comment on possible producer response (
                    e.g.,
                     how many manufacturers may choose to take voluntary action in response to this rule, what share of standardized food products may get reformulated) and on possible consumer willingness to purchase and consume such products with various types of salt substitutes at various levels, which would allow us to provide a range of net social benefit estimates when this rule is finalized.
                
                A. Economic Analysis of Impacts
                1. Background
                
                    There are 80 SOI that specify salt as a mandatory or optional ingredient. Some of these standards are referenced by other SOI, resulting in salt as an ingredient in 140 SOI. The salt in the foods covered by these 140 SOI may serve a variety of functions such as taste, texture, moisture control, and microbial safety. FDA has a public health interest in reducing sodium across the food supply. Therefore, we propose to give manufacturers the flexibility to use salt substitutes in standardized foods where salt is a required or optional ingredient, to reduce the sodium content. While there may be potential data sources (
                    e.g.,
                     IRI, Label Insight, Mintel, NHANES, Syndigo) that could provide market or consumption share (
                    e.g.,
                     contribution of sodium and/or caloric intake) for foods covered by these 140 SOI, FDA does not currently have sufficient estimates to further extrapolate impacts at this time. We request public comment on additional potential data sources for estimates of market share and/or caloric and/or sodium consumption share of the products included in these SOI.
                
                
                    We request comment on potential regulatory alternatives including allowing the use of only specified salt substitutes, at only specified levels of substitution, for only specified 
                    
                    purposes, for only specified products, in conjunction with only specified ancillary formulation changes, or with specified labeling requirements. More generally, we request comments on potential regulatory approaches to reducing salt in food or the dietary intake of salt that do not involve allowing the use of salt substitutes in standardized foods.
                
                2. Benefits of the Proposed Rule
                The benefit of this proposed rule is that manufacturers would have additional flexibility in producing standardized foods covered by 140 SOI, which may lead to social benefits in the form of increased consumer satisfaction (consumer surplus), increased profits (producer surplus), or both. In addition, a change in voluntary market behavior relating to patterns of food consumption, or to use a potassium-based salt as a salt substitute and consumers who would benefit from increasing their potassium intake choose to consume those products, those consumers may experience positive health effects.
                Salt is a relatively inexpensive ingredient, and we would not expect manufacturers to begin using salt substitutes based on cost cutting considerations alone at this time. To explore the possibility of manufacturers voluntarily replacing salt with salt substitutes to improve the healthfulness of their standardized foods, one would need to identify the costs and level of potential substitution, and extent of consumer acceptance of salt substitutes at differing levels in different standardized foods in order to estimate the number of manufacturers who would decide to use salt substitutes. We currently lack data on these potential industry responses and request public comment from manufactures, suppliers, and consumers on the extent to which the additional flexibility provided by this rule would be used by manufacturers, hence also desired or tolerated by consumers, and viable in the supply chain.
                
                    As discussed in the preamble of this rule, on average, Americans consume approximately 3,400 milligrams of sodium per day (mg/day), which is nearly 50 percent more than the recommended daily limit on sodium intake for individuals 14 years and older (Refs. 1 and 2). Excess sodium intake increases the risk for hypertension, or high blood pressure, a leading cause of heart disease and stroke (Refs. 26). Decreasing sodium consumption is expected to reduce hypertension and potentially result in fewer cases of heart disease and stroke (Refs. 79 
                    2
                    
                    ). More than 70 percent of sodium consumed in the U.S. comes from sodium added during manufacturing and commercial food preparation (Ref. 14). The health benefits from reducing sodium consumption are expected to be higher for populations that currently have higher sodium consumption or that are more sensitive to any given level of sodium consumption than other populations. Hence, there may be potential health equity effects to any regulation that generates or facilitates reduced intake of sodium. In order to estimate such health benefits, we would need data and information on the complex pathway between allowing manufactures to use salt substitutes, the extent to which manufactures will develop products of interest to those at highest risk of hypertension, the likely demographic patterns of consumers purchasing those new products, and eventually, the extent of the reduction in sodium uptake among those at most risk of hypertension.
                
                
                    
                        2
                         These studies may be sensitive to assumptions regarding consumer response. If some consumers experience disutility associated with the reformulated product and adjust their consumption pattern accordingly, this could partially offset some of the estimated health benefits.
                    
                
                
                    In the absence of necessary data to fully estimate the impacts of this rule, we refer to published literature on the health benefits of sodium reduction targets to provide broader context of potential impacts of this rule. A 2018 study by Pearson-Stuttard, et al. looked at the health and economic effects of FDA's 2016 draft voluntary sodium reduction guidance (Refs. 8 and 22) and estimated benefits of meeting sodium reduction targets in the form of medical cost savings and consumer health improvements, net of producer reformulation costs and some government administrative and monitoring costs. Over a 20-year period, the authors of the study find net social benefits from only consumer health effects to be roughly $12 billion (uncertainty range of $0 billion to $28 billion) under what it described as the most pessimistic scenario relating to potential sodium reduction among the three presented (Ref. 8). This roughly $12 billion 
                    net
                     benefit arises from roughly $19 billion in estimated health cost savings (benefits) and just over $7 billion of estimated reformulation, administrative and monitoring costs.
                    3
                    
                
                
                    
                        3
                         These results may be sensitive to assumptions regarding consumer response to product reformulation. For example, benefits might be lower if some consumers experience disutility associated with the reformulated product and adjust their consumption pattern accordingly, which could partially offset the estimated health benefits presented above. Ref. 9, for instance, indicates that its cost-effectiveness results are highly sensitive to such issues.
                    
                
                Since these benefit estimates are not comprehensive, we would need additional data on possible producer and consumer response to fully assess health benefits. Moreover, benefits might be higher or lower than what would be indicated by estimates that focus on the subset of effects tracked by Pearson-Stuttard et al. Benefits might be higher if firms were to realize additional profits or producer surplus from any product reformulation (since we assume firms would use salt substitutes only if profits would remain the same or increase). Benefits might also be higher due to possible changes in consumer surplus from consumers willing to buy reformulated products whose valuation includes factors beyond medical cost savings or health state utility. Benefits might be lower if some consumers experience disutility associated with the reformulated product and adjust their consumption pattern accordingly, which could partially offset the estimated health benefits presented above.
                In addition, as mentioned above, we currently lack data to determine how much, if any, of the aggregate effects that Pearson-Stuttard et al. attribute to broader voluntary sodium reduction efforts could be directly connected to the flexibility provided by this rule. The rule does not cover all foods analyzed in the Pearson-Stuttard, et al. scenarios, which included many non-standardized foods. With comprehensive data on the share of foods affected by this rule, we could estimate health benefits across only such products as a subset of the Pearson-Stuttard, et al. estimate. We request such data and also data on possible consumer and producer response to the flexibility provided by this rule.
                3. Costs of the Proposed Rule
                
                    The proposed rule, if finalized would not impose 
                    regulatory
                     costs on manufacturers or consumers. There would be no regulatory requirements or regulatory penalties relative to the baseline of taking no regulatory action. Manufacturers would be required to use safe and suitable ingredients regardless of the amount or type of salt substitutes they choose to use. The flexibility provided by this rule creates parity for use of existing salt substitutes in both standardized and non-standardized foods (see section V.C. for discussion of examples of current salt substitutes in use) and such uses are already required to be disclosed and labeled. It is 
                    
                    possible that a change in voluntary market behavior relating to food consumption may generate health costs. For example, to the extent manufacturers choose to use potassium chloride as a salt substitute and consumers choose to consume those products, consumers who may need to limit their potassium intake may see negative health effects that should be accounted for in cost estimates. We request comments on evidence that could contribute to a more thorough assessment (including possible quantification) of such costs. The agency will continue to monitor the use of salt substitutes in the U.S. food supply.
                
                The economic rationale for food standards involves reducing consumers' search costs; in particular, their ability to infer certain product characteristics from representation as certain standardized foods. The proposed rule may affect product characteristics by allowing manufacturers to use salt substitutes that replace any one or any combination of the functions of added salt. However, the proposed rule would preclude ingredient substitutions that change the basic nature and essential characteristics of a standardized food. The basic nature of a food concerns the general attributes of the product that is offered for sale to consumers. The essential characteristics of a food may contribute to achieving the basic nature of the food, but consumers may not be aware of the essential characteristics. Use of safe and suitable salt substitutes that do not change the basic nature and essential characteristics of the standardized food ensures that products on the market retain their general attributes. For purposes of this analysis, we assume products that retain their general attributes will also retain consistency with consumer beliefs and expectations relating to those products and that the use of salt substitutes will therefore not generate consumer dissatisfaction relating to the identity of the standardized food. To the extent that this assumption may not be accurate, we request comment on the degree to which consumers may be willing to purchase and consume such products after salt substitutes are used.
                If finalized, manufacturers may choose to take advantage of the flexibility provided in this proposed rule. As discussed above, the primary potential costs of that voluntary market behavior would arise from producers choosing to use the flexibility afforded to them to reformulate some products such as reformulation, consumer testing, labeling, and possibly marketing costs. Pearson-Stuttard, et al., estimate that reformulation costs (using the FDA model, Ref. 23) corresponding to the draft voluntary short term sodium reduction targets could range from $2.7 to $15 billion over a 20-year time period and that these costs would comprise roughly 95 percent of the costs related to reaching short term sodium reduction targets (Ref. 8). Producers may voluntarily choose to reformulate some products in response to this rule's added flexibility and the magnitude of such costs would depend on the number of products reformulated. The more firms choose to reformulate using salt substitutes given the flexibility provided by this rule, the greater the share of sodium reduction efforts (and associated reformulation costs) that could be attributed to this rule. Regardless of what amount of reformulation producers voluntarily choose to undertake, they will only do so if their private benefits in the form of increased revenue are at least as much as their private costs. We request comment on the number of manufacturers who may choose to reformulate standardized food products and the extent to which manufacturers may choose to reformulate those products given this new flexibility. We also request comment on all other considerations relating to manufacturers' voluntary market decision to use salt substitutes including cost of reformulation, ability to source substitute ingredients, expected impact on sales, profits, and consumer acceptance or lack of acceptance.
                B. Initial Small Entity Analysis
                The Regulatory Flexibility Act requires Agencies to analyze regulatory options that would minimize any significant impact of a rule on small entities. If finalized, we do not expect the proposed rule would generate impacts on small entities. The rule would not impose regulatory costs on small entities. There would be no regulatory requirements or regulatory penalties relative to the baseline of taking no regulatory action. We have no basis to suppose or estimate any other impacts on small entities. As a result, we propose to certify that the proposed rule will not have a significant economic impact on a substantial number of small entities. This analysis, as well as other sections in this document, serves as the Initial Regulatory Flexibility Analysis, as required under the Regulatory Flexibility Act.
                
                    This analysis is also available in the docket for this proposed rule (Ref. 24) and at 
                    https://www.fda.gov/about-fda/reports/economic-impact-analyses-fda-regulations.
                
                VIII. Analysis of Environmental Impact
                We have determined under 21 CFR 25.32(a) that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required.
                IX. Paperwork Reduction Act of 1995
                FDA tentatively concludes that this proposed rule contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.
                X. Federalism
                We have analyzed this proposed rule in accordance with the principles set forth in Executive Order 13132. We have determined that the proposed rule does not contain policies that have substantial direct effects on the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government. Accordingly, we conclude that the rule does not contain policies that have federalism implications as defined in the Executive Order and, consequently, a federalism summary impact statement is not required.
                XI. Consultation and Coordination With Indian Tribal Governments
                We have analyzed this proposed rule in accordance with the principles set forth in Executive Order 13175. We have tentatively determined that the rule does not contain policies that would have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.

                    Self-rising flour.
                    
                        (a) 
                        Description.
                         Self-rising flour, self-rising white flour, self-rising wheat flour, is an intimate mixture of flour, sodium bicarbonate, and one or more of the acid-reacting substances monocalcium phosphate, sodium acid pyrophosphate, and sodium aluminum phosphate. It is seasoned with salt or salt substitute. When it is tested by the method prescribed in paragraph (c) of this section, not less than 0.5 percent of carbon dioxide is evolved. The acid-reacting substance is added in sufficient quantity to neutralize the sodium bicarbonate. The combined weight of such acid-reacting substance and sodium bicarbonate is not more than 4.5 parts to each 100 parts of flour used. Subject to the conditions and restrictions prescribed by  137.105(a), the bleaching ingredients specified in such section may be added as optional ingredients. If the flour used in making the self-rising flour is bleached, the optional bleaching ingredient used therein (see  137.105(a)) is also an optional ingredient of the self-rising flour.
                    
                    
                    
                        (c) 
                        Method of analysis.
                         Follow the method prescribed in AOAC Official Method 923.02A, Reagent, and 923.02B, Apparatus, under Carbon Dioxide (Total) in Baking Powders Gasometric Determination (incorporated by reference, see  137.10): Instead of using AOAC Official Method 923.02C, Determination, use the following procedure:
                    
                    (1) Weigh 17 grams of the official sample into flask A, add 1520 glass beads (46 mm. diameter), and connect this flask with the apparatus (fig. 923.02). Open stopcock C and by means of the leveling bulb E bring the displacement solution to the 25 cc. graduation above the zero mark. (This 25 cc. is a partial allowance for the volume of acid to be used in the decomposition.) Allow the apparatus to stand 12 minutes to ensure that the temperature and pressure within the apparatus are the same as those of the room. Close the stopcock, lower the leveling bulb somewhat to reduce the pressure within the apparatus, and slowly run into the decomposition flask from burette F 45 cc. of sulfuric acid (1 + 5). To prevent the liberated carbon dioxide from escaping through the acid burette into the air, keep the displacement solution in the leveling bulb at all times during the decomposition at a lower level than that in the gas-measuring tube. Rotate and then vigorously agitate the decomposition flask for 3 minutes to mix the contents intimately. Allow to stand for 10 minutes to bring to equilibrium. Equalize the pressure in the measuring tube by means of the leveling bulb and read the volume of gas from the zero point on the tube. Deduct 20 cc. from this reading (this 20 cc. together with previous allowance of 25 cc. compensates for the 45 cc. acid used in the decomposition). Observe the temperature of the air surrounding the apparatus and also the barometric pressure and multiply the number of milliliters of gas evolved by the factor given in Reference Table 909.04, Correction Factors for Gasometric Determination of Carbon Dioxide, incorporated by reference, see  137.10) for the temperature and pressure observed. Divide the corrected reading by 100 to obtain the apparent percent by weight of carbon dioxide in the official sample.
                    
                
                57. In  137.270, revise paragraphs (a), (b) introductory text, and (b)(1) to read as follows:

                        (a) 
                        Description.
                         Self-rising white corn meal is an intimate mixture of white corn meal, sodium bicarbonate, and one or both of the acid-reacting substances monocalcium phosphate and sodium aluminum phosphate. It is seasoned with salt or salt substitute. When it is tested by the method prescribed in paragraph (b) of this section, not less than 0.5 percent of carbon dioxide is evolved. The acid-reacting substance is added in sufficient quantity to neutralize the sodium bicarbonate. The combined weight of such acid-reacting substance and sodium bicarbonate is not more than 4.5 parts to each 100 parts of white corn meal used.

                         Canned applesauce is the food prepared from comminuted or chopped apples (
                        Malus domestica
                         Borkhausen), which may or may not be peeled and cored, and which may have added thereto one or more of the optional ingredients specified in paragraph (a)(2) of this section. The apple ingredient is heated and, in accordance with good manufacturing practices, bruised apple particles, peel, seed, core material, carpel tissue, and other coarse, hard, or extraneous materials are removed. The food is sealed in containers. It is so processed by heat, either before or after sealing, as to prevent spoilage. The soluble solids content, measured by refractometer and expressed as percent sucrose (degrees Brix) with correction for temperature to the equivalent at 20 C (68 F), is not less than 9 percent (exclusive of the solids of any added optional nutritive carbohydrate sweeteners) as determined by AOAC Official Method 932.12 but without correction for invert sugar or other substances. AOAC Official Method 932.12, Solids (Soluble) in Fruits and Fruit Products, in Official Methods of Analysis of AOAC INTERNATIONAL, 21st Ed. (2019), is incorporated by reference into this section with the approval of the Director of the Federal Register under 5 U.S.C. 552(a) and 1 CFR part 51,.

                         Tomato juice is the food intended for direct consumption, obtained from the unfermented liquid extracted from mature tomatoes of the red or reddish varieties of 
                        Lycopersicum esculentum
                         P. Mill, with or without scalding followed by draining. In the extraction of such liquid, heat may be applied by any method which does not add water thereto. Such juice is strained free from peel, seeds, and other coarse or hard substances, but contains finely divided insoluble solids from the flesh of the tomato in accordance with current good manufacturing practice. Such juice may be homogenized, may be seasoned with salt or salt substitute, and may be acidified with any safe and suitable organic acid. The juice may have been concentrated and later reconstituted with water and/or tomato juice to a tomato soluble solids content of not less than 5.0 percent by weight as determined by the method prescribed in  156.3(b). The food is preserved by heat sterilization (canning), refrigeration, or freezing. When sealed in a container to be held at ambient temperatures, it is so processed by heat, before or after sealing, as to prevent spoilage.

                        (1) Canned oysters is the food prepared from one or any mixture of two or all of the forms of oysters 
                        
                        specified in paragraph (a)(2) of this section, and a packing medium of water, or the watery liquid draining from oysters before or during processing, or a mixture of such liquid and water. The food may be seasoned with salt or salt substitute. It is sealed in containers and so processed by heat as to prevent spoilage.
                    
                    
                    (c) * * *
                    (3) Drained weight is determined by the following method: Keep the unopened canned oyster container at a temperature of not less than 68 F or more than 95 F for at least 12 hours immediately preceding the determination. After opening, tilt the container so as to distribute its contents evenly over the meshes of a circular sieve that has been previously weighed. The diameter of the sieve is 8 inches if the quantity of the contents of the container is less than 3 pounds and 12 inches if such quantity is 3 pounds or more. The bottom of the sieve is woven-wire cloth that complies with the specifications for such cloth set forth under 2.36 mm (No. 8) in Official Methods of Analysis, Table 1, Nominal Dimensions of Standard Test Sieves (USA Standard Series), under the heading Definition of Terms and Explanatory Notes, (incorporated by reference, see  161.10). Without shifting the material on the sieve, so incline the sieve as to facilitate drainage. Two minutes from the time drainage begins, weigh the sieve and the drained oysters. The weight so found, less the weight of the sieve, shall be considered to be the drained weight of the oysters.

                    (c) * * *
                    (1) The standard of fill of transparent or nontransparent containers for canned wet pack shrimp is a fill such that the cut-out weight of shrimp taken from each container is not less than 60 percent of the weight of the water required to fill the container. The weight of the water required to fill the container is determined by the general method provided in  130.12(a) of this chapter. Cut-out weight is determined by the following method: Keep the unopened canned shrimp container at a temperature of not less than 68 F nor more than 75 F for at least 12 hours immediately preceding the determination. After opening, distribute the shrimp evenly over the meshes of a circular sieve that has been previously weighed. The diameter of the sieve is 20.3 centimeters (8 inches) if the quantity of the contents of the container is less than 1.36 kilograms (3 pounds), and 30.5 centimeters (12 inches) if such quantity is 1.36 kilograms (3 pounds) or more. The bottom of the sieve is woven-wire cloth that complies with the specifications for such cloth set forth as a 2.36 mm (No. 8) sieve in Official Methods of Analysis (incorporated by reference, see  161.10), Table 1, Nominal Dimensions of Standard Test Sieves (USA Standard Series), under the heading Definition of Terms and Explanatory Notes (incorporated by reference, see  161.10) Without shifting the material on the sieve, incline the sieve at an angle of approximately 17 to 20 to facilitate drainage. Allow the shrimp to drain for 2 minutes, measured from the moment the product is poured onto the sieve. Weigh the sieve and the drained shrimp. The weight so found, less the weight of the sieve, shall be considered to be the cut-out weight of the shrimp.
                    
                
                87. In  161.190, revise paragraphs (a)(6)(i) and (a)(7) introductory text to read as follows:

                        (7) For determination of the color designations specified in paragraph (a)(4) of this section, the following method shall be used: Recombine the separations of pressed cake resulting from the method prescribed in paragraph (c)(2) of this section. Pass the combined portions through a sieve fitted with woven-wire cloth of 
                        1/4
