Judith Kidwell, Center for Food Safety and Applied Nutrition (CFSAN) (HFS-265), Food and Drug Administration, 5001 Campus Dr., College Park, MD 20740-3835, 240-402-1071.
In the Federal Register on October 7, 2016 (81 FR 69740), we announced that we filed a color additive petition (CAP 6C0307) submitted by Wm. Wrigley Jr. Company (petitioner), c/o Exponent, 1150 Connecticut Ave. NW., Suite 1100, Washington, DC 20036. The petition proposed to amend the color additive Start Printed Page 51555regulations in part 73 (21 CFR part 73) Listing of Color Additives Exempt from Certification to provide for the safe use of calcium carbonate to color hard and soft candy, mints, and chewing gum. The proposed use excludes chocolate or the chocolate portion of candy, as the current standards of identity for chocolate do not allow for the addition of color additives (see 21 CFR 163.123, 163.124, 163.130, 163.135, 163.140, 163.145, 163.153, 163.155). After the petition was filed, the petitioner clarified that calcium carbonate is intended for use only in ink applied to the surface of the chewing gum.
Calcium carbonate is obtained from ground limestone or produced synthetically through a precipitation process using calcium oxide, water, and carbon dioxide. Calcium is abundant in the human body and is an integral component of bones, teeth, and other biological structures. Calcium constantly diffuses in and out of the bone and is resorbed by the kidney. Excess intake of calcium may result in hypercalcemia, hypercalciuria, gastrointestinal issues, kidney stones, interference with iron and zinc absorption, possible vascular and soft tissue calcification, and renal and cardiovascular damage. Carbonate is present in the human body as a critical component of the pH buffering system. The components of carbonate (carbon and oxygen) are ubiquitous in the human diet and body, and carbonate itself does not belong to a class of structures that is associated with any adverse effects or toxicity.
Calcium carbonate that is pharmaceutical grade is currently approved under § 73.1070 for use as a color additive in drugs in amounts consistent with good manufacturing practices (GMP). Additionally, food grade calcium carbonate and ground limestone (consisting of not less than 94 percent calcium carbonate) are affirmed as generally recognized as safe in § 184.1191 and § 184.1409 (21 CFR 184.1191 and 184.1409), respectively. These regulations do not include limitations for use in food other than current GMP. The petitioner proposed that to ensure that only food grade calcium carbonate is used to color hard and soft candy, mints, and chewing gum, the substance must meet the specifications of the Food Chemicals Codex, 10th edition (FCC 10). We have reviewed these specifications and agree that they should be incorporated into the regulation as set forth in this document. The petitioner proposed to use calcium carbonate to color soft and hard candy, mints, and chewing gum in amounts consistent with GMP. The maximum GMP use level for calcium carbonate in hard and soft candy, mints, and chewing gum will be determined by the desired coloring effect. We have determined that the amount of calcium carbonate used in these foods is self-limiting because the addition of the color additive above a certain level will not achieve the desired coloring effect and negatively interferes with organoleptic properties, such as taste and texture. Because the amount of the color additive used in these foods is self-limiting, we have determined that there is no need for a specific upper limit on the percent by weight of calcium carbonate in hard and soft candy, mints, and chewing gum (Ref. 1).
Under section 721(b)(4) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 379e(b)(4)), a color additive cannot be listed for a particular use unless the data and information available to FDA establish that the color additive is safe for that use. Furthermore, under section 721(b)(4) of the FD&C Act, a color additive is deemed to be suitable and safe for the purpose of listing for use generally in or on food, while there is in effect a published finding declaring such substance exempt from the term “food additive” because of its being generally recognized by qualified experts as safe for its intended use, as provided in section 201(s) of the FD&C Act (21 U.S.C. 321(s)). FDA's color additive regulations in 21 CFR 70.3(i) define “safe” to mean that there is convincing evidence that establishes with reasonable certainty that no harm will result from the intended use of the color additive.
To establish with reasonable certainty that a color additive intended for use in foods is not harmful under its intended conditions of use, we consider the projected human dietary exposure to the color additive, the additive's toxicological data, and other relevant information (such as published literature) available to us. We compare an individual's estimated exposure, or estimated daily intake (EDI), of the color additive from all food sources to an acceptable daily intake level established by toxicological data. The EDI is determined by projections based on the amount of the color additive proposed for use in particular foods or drugs and on data regarding the amount consumed from all sources of the color additive. We commonly use the EDI for the 90th percentile consumer of a color additive as a measure of high chronic exposure.
The petitioner indicated that, given the types of candies to be colored and the variable conditions under which calcium carbonate would be used, the use of the assumption that all candies would contain calcium carbonate at the maximum GMP level would lead to an overestimate of exposure. However, because only hard and soft candy, mints, and chewing gum that are colored white would result in a potential exposure to calcium carbonate from the proposed use, the petitioner reviewed the 2009-2012 National Health and Examination Survey (NHANES) food codes and identified 51 food codes in which calcium carbonate could potentially be used as a color additive that represent the intended use in hard and soft candy, mints, and chewing gum. Although we identified additional food codes that could contain calcium carbonate, these codes were intentionally excluded by the petitioner because there were no associated eating occasions for these additional food codes over the survey years. We agree with the selected 51 food codes and the exclusion of the other food codes (Ref. 2). Furthermore, the petitioner used market data to refine their exposure estimate; however, these data were limited to those products that were introduced in the last 5 years and may not fully represent the market. Therefore, to be conservative, we estimated exposure to calcium carbonate using 2-day food consumption data from the 2009-2012 NHANES for the identified 51 food codes at the GMP use levels and made no adjustment for market data. Exposure to calcium carbonate and to calcium was estimated for the U.S. population 2 years of age and older and children 2 to 5 years of age (Ref. 2).
For the U.S. population 2 years of age and older, exposure estimates for calcium carbonate at the mean and 90th percentile from the proposed uses were 170 milligrams/person/day (mg/p/d) and 400 mg/p/d, respectively. For children 2 to 5 years of age, exposure estimates for calcium carbonate at the mean and 90th percentile were 125 mg/p/d and 270 mg/p/d, respectively.
Calcium carbonate is a source of calcium for the consumer once ingested and metabolized by the body. Therefore, as part of our evaluation, we also estimated exposure to calcium from the petitioned uses of calcium carbonate by assuming that the amount of calcium provided by calcium carbonate as a color additive is 40 percent of the total weight of calcium carbonate. For the U.S. population 2 years of age and older, Start Printed Page 51556estimated exposure to calcium from the proposed uses of calcium carbonate at the mean and 90th percentile were 70 mg/p/d and 160 mg/p/d, respectively. For children 2 to 5 years of age, estimated exposure to calcium at the mean and 90th percentile were 50 mg/p/d and 110 mg/p/d, respectively.
Additionally, we estimated exposure to calcium from background dietary sources, drugs, and dietary supplements using 2-day food consumption data for all foods and nutrient data for calcium in those foods based on the U.S. Department of Agriculture's National Nutrient Database for Standard Reference. This estimate also included exposure to calcium from dietary supplements (including non-prescription antacids that contain calcium) based on NHANES 2-day survey data (Ref. 2).
For the U.S. population 2 years of age and older, exposure to calcium from background dietary sources, drugs, and dietary supplements at the mean and 90th percentile were estimated to be 1,125 mg/p/d and 1,900 mg/p/d, respectively. For children 2 to 5 years of age, exposure estimates at the mean and 90th percentile were 1,000 mg/p/d and 1,600 mg/p/d, respectively. Because our exposure estimates for dietary supplements include calcium from all sources, not just calcium carbonate, we believe that this exposure estimate is sufficiently conservative to include any exposure to calcium from the use of calcium carbonate to color drugs (Ref. 2).
We estimated exposure to calcium from background dietary sources, drugs, dietary supplements and the proposed uses of calcium carbonate at the mean and 90th percentile for the U.S. population 2 years of age and older and children 2 to 5 years of age. Based on these calculations, exposure estimates for calcium for the U.S. population 2 years of age and older at the mean and 90th percentile were 1,150 mg/p/d and 1,925 mg/p/d, respectively. For children 2 to 5 years of age, exposure estimates for calcium at the mean and 90th percentile were 1,025 mg/p/d and 1,625 mg/p/d, respectively (Ref. 2).
To support the safety of the petitioned use of calcium carbonate, the petitioner referenced safety information on calcium from the 2011 Institute of Medicine (IOM) Report on Dietary Reference Intakes for Calcium and Vitamin D (Ref. 3) and the European Food Safety Authority (EFSA) Panel on Dietetic Products, Nutrition and Allergies' reevaluation of the safety of calcium (Ref. 4). In 2011, the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes of the Food and Nutrition Board of the IOM conducted an extensive review of relevant published scientific literature on calcium to update current dietary reference intakes and Upper Tolerable Intake Levels (UL). In their 2011 assessment of calcium, the IOM established a UL of 1,000 mg/p/d for infants 0 to 6 months of age and 1,500 mg/p/d for infants 6 to 12 months of age. For children 1 to 8 years of age, IOM did not change the UL of 2,500 mg/p/d from the previous IOM report in 1997. For children 9 to 18 years of age, IOM increased the UL to 3,000 mg/p/d. For adults 19 to 50 years of age, the IOM established a UL of 2,500 mg/p/d; for adults 51 years and older, the IOM established a UL of 2,000 mg/p/d.
The IOM considers the UL as the highest average daily intake level of a nutrient that poses no risk of adverse effects when the nutrient is consumed over long periods of time. The UL is determined using a risk assessment model developed specifically for nutrients. The dose-response assessment, which concludes with an estimate of the UL, is built upon three toxicological concepts commonly used in assessing the risk of exposures to chemical substances: No-observed-adverse-effect level, lowest-observed-effect level, and application of an uncertainty factor. We considered the ULs established by the IOM relative to the exposure estimates for calcium as the primary basis for assessing the safety of the petitioned uses of calcium carbonate.
The estimated dietary exposure to calcium from the petitioned uses, dietary sources, and dietary supplements at the 90th percentile for the U.S. population 2 years of age and older is estimated to be 1,925 mg/p/d, which is below the IOM's UL of 2,000-3,000 mg/p/d. For children 2 to 5 years of age, the exposure estimate at the 90th percentile is 1,625 mg/p/d, which also is below the IOM's UL of 2,500 mg/p/d for this age group. Additionally, the body of literature on calcium carbonate and calcium does not present evidence of safety concerns at the expected dietary exposures discussed above. Thus, we conclude that the petitioned use of calcium carbonate as a color additive in soft and hard candy, mints, and chewing gum is safe (Ref. 5).
FDA is incorporating by reference the Food Chemicals Codex, 10th ed. (2016), pp. 213-214 (calcium carbonate) and p. 754 (limestone, ground), which was approved by the Office of the Federal Register.

The FCC is a compendium of internationally recognized standards for the purity and identity of food ingredients. To ensure that only food grade calcium carbonate and ground limestone (consisting of not less than 94 percent calcium carbonate) are used in hard and soft candy, mints, and chewing gum, the additive must meet the specifications and identity in the appropriate FCC monograph.
FDA reviewed the data and information in the petition and other available relevant material and determined the use of calcium carbonate to color hard and soft candy, mints, and chewing gum at GMP levels is safe. We further conclude that the additive will achieve its intended technical effect and is suitable for the petitioned uses. We note that these uses do not extend to chocolate or the chocolate portion of candy because the standards of identity for chocolate do not allow for the addition of color additives (see 21 CFR 163.123, 163.124, 163.130, 163.135, 163.140, 163.145, 163.153, 163.155). Based on the available information, we are amending the color additive regulations in part 73 as set forth in this document. In addition, based on the factors listed in 21 CFR 71.20(b), we conclude that certification of calcium carbonate to color hard and soft candy, mints, and chewing gum is not necessary for the protection of public health (Ref. 1).
We previously considered the environmental effects of this rule, as stated in the October 7, 2016, Federal Register notice of petition for CAP 6C0307 (81 FR 69740). We stated that we had determined, under 21 CFR Start Printed Page 5155725.32(k), that this action “is of a type that does not individually or cumulatively have a significant effect on the human environment” such that neither an environmental assessment nor an environmental impact statement is required. We have not received any new information or comments that would affect our previous determination.
Our review of this petition was limited to section 721 of the FD&C Act. This final rule is not a statement regarding compliance with other sections of the FD&C Act. For example, section 301(ll) of the FD&C Act (21 U.S.C. 331(ll)) prohibits the introduction or delivery for introduction into interstate commerce of any food that contains a drug approved under section 505 of the FD&C Act (21 U.S.C. 355), a biological product licensed under section 351 of the Public Health Service Act (42 U.S.C. 262), or a drug or biological product for which substantial clinical investigations have been instituted and their existence has been made public, unless one of the exemptions in section 301(ll)(1) to (ll)(4) of the FD&C Act applies. In our review of this petition, we did not consider whether section 301(ll) of the FD&C Act or any of its exemptions apply to food containing this color additive. Accordingly, this final rule should not be construed to be a statement that a food containing this color additive, if introduced or delivered for introduction into interstate commerce, would not violate section 301(ll) of the FD&C Act. Furthermore, this language is included in all color additive final rules that pertain to food and therefore should not be construed to be a statement of the likelihood that section 301(ll) of the FD&C Act applies.
