(a) (A) classification. Canned blueberries that possess a very good color may be given a score of 18 to 20 points. "Very good color" means a practically uniform, bright, dark blue-purple color typical of blueberries which had been properly processed from well-matured blueberries.

(b) (B) classification. If the canned blueberries possess a good color, a score of 16 or 17 points may be given. Canned blueberries that fall into this classification shall not be graded above U. S. Grade B or U. S. Choice, regardless of the total score for the product (this is a limiting rule). "Good color" means a reasonably uniform, dark blue-purple color typical of blueberries which had been properly processed from reasonably well-matured blueberries.

(c) (C) classification. If the canned blueberries possess a fairly good color, a score of 14 or 15 points may be given. Canned blueberries that fall into this classification shall not be graded above

U. S. Grade C or U. S. Standard, regardless of the total score for the product (this is a limiting rule). "Fairly good color" means a blue-purple color typical of blueberries which had been properly processed and which are not off color for any reason.

Canned

(d) (SStd) classification. blueberries that fail to meet the requirements of paragraph (c) of this section may be given a score of 0 to 13 points and shall not be graded above U. S. Grade D or Substandard, regardless of the total score for the product (this is a limiting rule).

§ 52.590 Absence of defects.

(a) General. The factor of absence of defects refers to the degree of freedom from harmless extraneous material (such as leaves and large stems); from clusters; from cap stems; from undeveloped berries, or edible berries other than blueberries; and from berries damaged by insect, pathological, or any other injury.

(1) "Cap stems" are small stems which attach berries to the branch and means single cap stems or joined double cap stems with or without berries attached.

(2) A "cluster" means three or more joined cap stems with or without berries attached.

(3) "Undeveloped berries" are mummified berries with wrinkled or tough skins or which may be pathologically defective.

(b) (A) classification. Canned blueberries that are practically free from defects may be given a score of 36 to 40 points. "Practically free from defects" means that the canned blueberries are reasonably free from cap stems and for each 20 ounces of net weight, or the equivalent thereof, there may be present:

(1) Not more than a total of 2 whole leaves or large stems, provided such whole leaves and any other portions of leafy material do not exceed 2 square inch;

(2) Not more than 5 berries that are undeveloped or edible berries other than blueberries or berries that are damaged; and

(3) In native (or wild) type, not more than an average of 12 clusters in all containers comprising the sample, provided there are no more than 16 clusters in any single container; or

(4) In cultivated type, not more than 4 clusters.

(c) (B) classification. If the canned blueberries are reasonably free from defects, a score of 32 to 35 points may be given. Canned blueberries that fall into this classification shall not be graded above U. S. Grade B or U. S. Choice, regardless of the total score for the product (this is a limiting rule). "Reasonably free from defects" means that the canned blueberries are reasonably free from cap stems and for each 20 ounces of net weight, or the equivalent thereof, there may be present:

(1) Not more than a total of 4 whole leaves or large stems, provided such whole leaves and any other portions of leafy material do not exceed 34 square inch;

(2) Not more than 8 berries that are undeveloped or edible berries other than blueberries or berries that are damaged; and

(3) In Native (or wild) type, not more than an average of 20 clusters in all containers comprising the sample, provided there are no more than 28 clusters in any single container; or

(4) In Cultivated type, not more than 8 clusters.

(d) (C) classification. If the canned blueberries are fairly free from defects, a score of 28 to 31 points may be given. Canned blueberries that fall into this classification shall not be graded above U. S. Grade C or U. S. Standard, regardless of the total score for the product (this is a limiting rule). "Fairly free from defects" means that the canned blueberries are fairly free from cap stems and for each 20 ounces of net weight, or the equivalent thereof, there may be present:

(1) Not more than a total of 6 whole leaves or large stems, provided such whole leaves and any other portions of leafy material do not exceed 1 square inch;

(2) Not more than 10 berries that are undeveloped or edible berries other than blueberries or berries that are damaged; and

(3) In Native (or wild) type, not more than an average of 28 clusters in all containers comprising the sample, provided there are no more than 40 clusters in any single container; or

that are practically free from defects; that possess a good character; that possess a normal flavor and odor; and are of such quality with respect to color as to score not less than 90 points when scored in accordance with the scoring system outlined in this subpart.

(b) "U. S. Grade B" or "U. S. Choice" is the quality of frozen blueberries that possess similar varietal characteristics; that possess a good color; that are reasonably free from defects; that possess a reasonably good character; that possess a normal 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" or "U. S. Standard" is the quality of frozen blueberries that possess similar varietal characteristics; that possess a fairly good color; that are fairly free from defects; that possess a fairly good character; that possess a normal flavor and odor; and that score not less than 70 points when scored in accordance with the scoring system outlined in this subpart.

(d) "U. S. Grade D" or "Substandard” is the quality of frozen blueberries that fail to meet the requirements of U. S. Grade C or U. S. Standard.

FACTORS OF QUALITY

§ 52.614 Ascertaining the grade.

(a) The grade of frozen blueberries may be ascertained by considering, in conjunction with the requirements of the respective grade, the respective ratings for the factors of color, absence of defects, and character.

[blocks in formation]

(c) The scores for the factors of color, absence of defects, and character of frozen blueberries are determined when the product is sufficiently free from ice crystals to permit handling of the blueberries.

(d) "Normal flavor and odor" means that the product is free from objectionable flavors and objectionable odors of any kind.

§ 52.615 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 such factors and expressed numerically. The numerical range within each factor which is scored is inclusive (for example, "18 to 20 points" means 18, 19, or 20 points).

§ 52.616 Color.

(a) (A) classification. Frozen blueberries that possess a very good color may be given a score of 18 to 20 points. "Very good color" means that the blueberries possess a practically uniform, bright, dark blue-purple color typical of properly matured berries for the variety and that there may be present not more than 5 percent by count of berries that possess a red-purple color. Frozen blueberries that are undercolored (not at least red-purple color) or that have a definite green cast are considered "green berries." (See § 52.617 (a).)

(b) (B) classification. If the frozen blueberries possess a good color, a score of 16 or 17 points may be given. "Good color" means that the blueberries possess a reasonably uniform, dark blue-purple color typical of reasonably well-matured berries for the variety and that there may be present not more than 10 percent by count of berries that possess a red-purple color. Frozen blueberries that are under-colored (not at least redpurple color) or that have a definite green cast are considered "green berries." (See § 52.617 (a).)

(c) (C) classification. If the frozen blueberries possess a fairly good color, a score of 14 or 15 points may be given. Frozen blueberries that fall into this classification shall not be graded above U. S. Grade C or U. S. Standard, regardless of the total score for the product (this is a limiting rule). "Fairly good color" means that the blueberries may be moderately variable in color, but are not definitely dull or off color, and there may be present not more than 20 percent by count of berries that possess a red-purple color. Frozen blue berries that are undercolored (not at least red-purple color) or that have a definite green cast are considered "green berries." (See § 52.617 (a).)

(d) (SStd) classification. Frozen blueberries that fail to meet the requirements of paragraph (c) of this section may be given a score of 0 to 13 points

and shall not be graded above U. S. Grade D or Substandard, regardless of the total score for the product (this is a limiting rule).
