for Grades of Frozen Mixed Vegetabl es

Effective August 29 , 2013This 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 2 4 , 19 5 4

.

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 qual ity. 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 pr oviding a convenient basis for buying and selling, for establishing quality control programs, and for determining loan values.

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

several fresh and processed fruits and v egetables are available on the i nternet 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 manual s obtained from:

(c) Five vegetables. A mixture of five basic vegetables in which none of the vegetables is less than 8 percent by weight nor more than 30 percent by weight of all the frozen mixed vegetables.United States Standards for Grades of Frozen Mixed Vegetables ( August 29 , 2013 )

3 §52.2134 Grades of frozen mixed vegetables.

(a) U.S. Grad e 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 odo r; 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 w hich 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

ch aracter, 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

4 (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 f or 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 object ionable 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 fa ctors 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 exa mple, 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

§52.2140 Explanation of terms and analyses.

(a) The proportion of ingredients are determined on the thawed vegetab les 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 fort h 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).
