United States Standards

for Grades of Frozen 

Mixed Vegetables

Effective August 29, 2013
This is the third issue, as amended, of the United States Standards for Grades of 

Frozen Mixed Vegetables published in the FEDERAL REGISTER of July 30, 2013 

(78 FR 45907) to become effective August 29, 2013. This issue supersedes the second

issue, which has been in effect since May 24, 1954. 

Voluntary U.S. grade standards are issued under the authority of the Agricultural 

Marketing Act of 1946, which provides for the development of official U.S. grades to 

designate different levels of quality. These grade standards are available for use by 

producers, suppliers, buyers, and consumers. As in the case of other standards for 

grades of fresh and processed fruits and vegetables, these standards are designed to 

facilitate orderly marketing by providing a convenient basis for buying and selling, for 

establishing quality control programs, and for determining loan values. 

The U.S. grade standards, grading manuals, handbooks or instructions for inspection of 

several fresh and processed fruits and vegetables are available on the internet and 

upon request at the address below. These manuals or instructions contain detailed 

interpretations of the grade standards and provide step-by-step procedures for grading 

the product. 

Grade standards are issued by the Department after careful consideration of all data 

and views submitted, and the Department welcomes suggestions which might aid in 

improving the standards in future revisions. Comments may be submitted to, and 

copies of standards and grading manuals obtained from:

§52.2131 Product description.

Frozen mixed vegetables consist of three or more succulent vegetables, properly 

prepared and properly blanched; may contain vegetables (such as, small pieces of 

sweet red peppers or sweet green peppers) added as garnish; and are frozen and 

maintained at temperatures necessary for the preservation of the product.

§52.2132 Kinds and styles of basic vegetables.

It is recommended that frozen mixed vegetables, other than small pieces of vegetables 

added as garnish, consist of the following kinds and styles of vegetables as basic 

vegetables: 

(a) Beans, green or wax: Cut styles, predominantly of 1/2 inch to 1-1/2 inch cuts;

§52.2134 Grades of frozen mixed vegetables.

(a) U.S. Grade A is the quality of frozen mixed vegetables in which each basic 

vegetable possesses similar varietal characteristics; in which all vegetables 

possess a good color, are practically free from defects, possess a good 

character, possess a good flavor and odor; and that score not less than 90 points 

when scored in accordance with the scoring system outlined in this subpart.

(b) U.S. Grade B is the quality of frozen mixed vegetables in which each basic 

vegetable possesses similar varietal characteristics; in which all vegetables 

possess a reasonably good color, are reasonably free from defects, possess a 

reasonably good character, possess a good flavor and odor; and that score not 

less than 80 points when scored in accordance with the scoring system outlined 

in this subpart.

(c) U.S. Grade C is the quality of frozen mixed vegetables in which each basic 

vegetable possesses similar varietal characteristics; in which all vegetables 

possess a fairly good color, are fairly free from defects, possess a fairly good 

character, possess a fairly good flavor and odor; and that score not less than 70 

points when scored in accordance with the scoring system outlined in this 

subpart.

(d) Substandard is the quality of frozen mixed vegetables that fail to meet the 

requirements of U.S. Grade C.

§52.2135 Ascertaining the grade.

(a) The grade of frozen mixed vegetables is ascertained by considering the factors 

of similar varietal characteristics and flavor and odor which are not scored and 

the respective ratings for the factors of color, absence of defects, and character 

which are scored.

(b) The relative importance of each factor which is scored is expressed numerically 

on the scale of 100. The maximum number of points that may be given such 

factors are:

(c) The scores for the factors of color, absence of defects, and character (with 

respect to each individual vegetable prior to cooking) are determined immediately 

after thawing so that the product is sufficiently free from ice crystals to permit 

proper handling as individual units, and representative samples of the product 

are cooked to ascertain tenderness of the frozen mixed vegetables, collectively, 

before final evaluation of the score for character. Flavor and odor are also 

ascertained on the cooked product.

(d) Good flavor and odor means that the product and each basic vegetable after 

cooking has a good, characteristic normal flavor and odor, free from 

objectionable flavors and objectionable odors of any kind.

(e) Fairly good flavor and odor means that the product after cooking may be 

lacking in good flavor and odor but is free from objectionable flavors and 

objectionable odors of any kind.

§52.2136 Ascertaining the rating for the factors which are scored.

The essential variations within each factor which is scored are so described that the 

value may be ascertained for each factor and expressed numerically. The numerical 

range within each factor which is scored is inclusive (for example, 17 to 20 points 

means 17, 18, 19, or 20 points).

§52.2137 Color.

(a) General. The factor of color refers to the general brightness of all the combined 

vegetables and to the colors of lima beans, if a component in the mixture, as 

follows:

(1) Green with respect to thin-seeded types (with skins removed), such as 

Henderson Bush and Thorogreen varieties, and with respect to thickseeded types (with skins on), such as Fordhook variety, means that the color 

of not less than 50 percent of the surface area of the individual lima bean 

possesses as much or more green color as Lima Bean Green in U.S. Color 

Standards for Frozen Lima Beans. 

(2) Green with respect to thick-seeded Baby Potato type (with skins on), such 

as Baby Potato, Baby Fordhook, and Evergreen varieties, means that the 

color of not less than 50 percent of the surface area of the individual lima bean 

possesses as much or more green color as Lima Bean Green in U.S. Color 

Standards for Frozen Lima Beans. 
United States Standards for Grades of Frozen Mixed Vegetables (August 29, 2013)

5

(3) White for the respective varietal types (with skins removed or with skins 

on, as the case may be) means that more than 50 percent of the surface area of 

the individual lima bean possesses less green color than Lima Bean White in 

U.S. Color Standards for Frozen Lima Beans.

(b) "A" classification. Frozen mixed vegetables which possess a good color may 

be given a score of 18 to 20 points. Good color means that the combined basic 

vegetables as a mass and the individual basic vegetables are bright and 

characteristic of young or tender vegetables that have been properly prepared 

and properly processed; that any pieces of vegetable material used for garnish 

are reasonably bright; and that lima beans, if present, possess a bright typical 

color for the varietal type and meet the following additional color requirements for 

the respective types:

(1) Thin-seeded type (with skins removed); Thick-seeded Baby Potato type 

(with skins on). 90 percent or more, by count, of all the lima beans are green; 

and the balance may be lighter in color or may be white or combinations thereof.

(2) Thick-seeded type (with skins on). 85 percent or more, by count, of all the lima 

beans are green; and the balance may be lighter in color but not more than 5 

percent, by count, of all the lima beans may be white.

(c) "B" classification. If the frozen mixed vegetables possess a reasonably good 

color, a score of 16 or 17 points may be given. Frozen mixed vegetables that 

fall into this classification shall not be graded above U.S. Grade B, regardless of 

the total score for the product (this is a limiting rule). Reasonably good color

means that the combined basic vegetables as a mass and the individual basic 

vegetables are reasonably bright and characteristic of reasonably young or 

reasonably tender mixed vegetables that have been properly prepared and 

properly processed; that any pieces of vegetable material used for garnish may 

be only fairly bright but are not off color for any reason; and that lima beans, if 

present, possess a reasonably bright typical color for the varietal type and meet 

the following additional color requirements for the respective types:

(1) Thin-seeded type (with skins removed); Thick-seeded Baby Potato type 

(with skins on). 65 percent or more, by count, of all the lima beans are green; 

and the balance may be lighter in color or may be white or combinations thereof.

(2) Thick-seeded type (with skins on). 60 percent or more, by count, of all the lima 

beans are green; and the balance may be lighter in color but not more than 5 

percent, by count, of all the lima beans may be white.
United States Standards for Grades of Frozen Mixed Vegetables (August 29, 2013)

(d) "C" classification. If the frozen mixed vegetables possess a fairly good color, 

a score of 14 or 15 points may be given. Frozen mixed vegetables that fall into 

this classification shall not be graded above U.S. Grade C, regardless of the total 

score for the product (this is a limiting rule). Fairly good color means that the 

combined basic vegetables as a mass and the individual basic vegetables are 

fairly bright and characteristic of mixed vegetables that have been properly 

prepared and properly processed; that any pieces of vegetable material used for 

garnish may be only fairly bright but are not off color for any reason; and that lima 

beans, if present, possess a fairly bright typical color for the varietal type and 

meet the following additional color requirements for the respective types:

(1) Thin-seeded type (with skins removed); Thick-seeded Baby Potato type 

(with skins on). More than 35 percent, by count, of all the lima beans are lighter 

than green including lima beans that may be white.

(2) Thick-seeded type (with skins on). More than 40 percent, by count, of all the 

beans are lighter than green but no more than 20 percent, by count, of all the 

lima beans may be white.

(e) "SStd" classification. If the frozen mixed vegetables fail to meet the 

requirements of paragraph (d) of this section, a score of 0 to 13 points may be 

given. Frozen mixed vegetables that fall into this classification shall not be 

graded above Substandard, regardless of the total score for the product (this is 

a limiting rule).

§52.2138 Absence of defects.

(a) General. The factor of absence of defects refers to the degree of freedom from 

harmless extraneous vegetable materials, slightly damaged units, moderately 

damaged units, seriously damaged units, and any other defects which detract 

from the appearance or edibility of the product.

(1) Harmless extraneous vegetable material means any vegetable substance 

other than from any of the basic vegetables or garnish and any portions of the 

basic vegetables which are normally removed in preparation for processing. 

Such materials include, but are not limited to, small pieces and large pieces as 

follows:

(i) A small piece of harmless extraneous vegetable material is any piece or unit 

of such material similar in shape and the equivalent in size or smaller than 3/16 

square inch of leafy material or loose pieces of pods from peas or lima beans, 

tough or woody stems of any size other than unstemmed units of green or wax 

beans, 1/4 inch cube of corn cob material, 1/2 square inch of corn husk, and 3/8

(e) "SStd" classification. If the frozen mixed vegetables fail to meet the 

requirements of paragraph (d) of this section, a score of 0 to 27 points may be 

given. Frozen mixed vegetables that fall into this classification shall not be 

graded above Substandard, regardless of the total score for the product (this is 

a limiting rule).

§52.2139 Character.

(a) General. The factor of character refers to the texture , the maturity, and the 

degree of development of the pods and seeds in green beans or wax beans; the 

tenderness of lima beans; the tenderness and the degree of freedom from stringy 

or coarse fibers in carrots; the tenderness and maturity or starchiness of the 

corn; the tenderness or maturity of the peas; and to the tenderness of the 

combined frozen mixed vegetables after cooking.

(b) Interpretation of terms. Unless indicated otherwise, the interpretation of the 

terms with respect to tenderness, texture, maturity, and development the 

individual vegetables prior to cooking are the same as those in the applicable 

United States Standards for Grades of the frozen product.

(c) "A" classification. Frozen mixed vegetables which collectively and individually 

possess a good character may be given a score of 36 to 40 points. Good 

character means that the combined vegetables after cooking are tender and that 

the individual vegetables prior to cooking meet the following requirements:

(1) Beans, green or wax. The bean pods and seeds possess a good character.

(2) Beans, lima. The lima beans, exclusive of white beans, are tender; and any 

white beans that may be present are tender or reasonably tender.

(3) Carrots. The units possess a tender texture.

(4) Corn. The kernels are no more advanced than the cream stage of maturity, 

have a reasonably tender texture, and are the equivalent of frozen whole-grain 

corn that would score not less than 43 points for the factor of Tenderness and 

Maturity as outlined in the United States Standards for Grades of Frozen Whole 

Kernel or Whole Grain Corn.

(5) Peas. The peas are reasonably tender and are the equivalent of frozen peas 

that would score not less than 34 points for the factor of Tenderness and 

Maturity as outlined in the United States Standards for Grades of Frozen Peas.

11

(d) "B" classification. If the frozen mixed vegetables, collectively and individually, 

possess a reasonably good character, a score of 32 to 35 points may be given. 

Frozen mixed vegetables that fall into this classification shall not be graded 

above U.S. Grade B, regardless of the total score for the product (this is a 

limiting rule). Reasonably good character means that the combined 

vegetables after cooking are reasonably tender and practically free from tough 

fibers and that the individual vegetables prior to cooking meet the following 

requirements:

(1) Beans, green or wax. The bean pods and seeds possess a reasonably good 

character.

limiting rule). Fairly good character means that the combined vegetables after 

cooking are fairly tender and reasonably free from tough fibers and that the 

individual vegetables prior to cooking meet the following requirements:

(1) Beans, green or wax. The bean pods and seeds possess a fairly good 

character.

(2) Beans, lima. The lima beans, including white beans that may be present, are 

fairly tender.

(3) Carrots. The units possess a reasonably tender texture.

(4) Corn. The kernels are fairly tender.

(5) Peas. The peas are fairly tender.

12

(f) "SStd" classification. If the frozen mixed vegetables, collectively or 

individually, fail to meet the requirements of paragraph (e) of this section, a score 

of 0 to 27 points may be given. Frozen mixed vegetables that fall into this 

classification shall not be graded above Substandard, regardless of the total 

score for the product (this is a limiting rule).

§52.2140 Explanation of terms and analyses.

(a) The proportion of ingredients are determined on the thawed vegetables by the 

following procedure:

(1) Separate and assemble from all the containers in the sample each of the basic 

vegetables;

(2) Weigh each basic vegetable thus composited to obtain the aggregate weight of 

each basic vegetable from all the containers in the sample;

(3) Add the aggregate weights of all the basic vegetables to obtain the grand total 

weight of all the basic vegetables from all containers in the sample; and then

(4) Calculate the percentage of each basic vegetable in the sample by dividing the 

aggregate weight of each basic vegetable by the grand total weight of all the 

basic vegetables.

§52.2141 Ascertaining the grade of a lot.

The grade of a lot of the processed product covered by these standards is determined 

by the procedures set forth in the Regulations Governing Inspection and 

Certification of Processed Fruits and Vegetables, Processed Products Thereof, 

and Certain Other Processed Food Products (§52.1 through §52.83).
