(b) “U. S. Grade B” or “U. S. Choice" is the quality of canned berries that possess similar varietal characteristics; that possess a reasonably good color; that are reasonably uniform in size; that are reasonably free from defects; that possess a reasonably good character; that possess a normal flavor and odor; and that for those factors which are scored in accordance with the scoring system outlined in this subpart, the total score is not less than 80 points: Provided, That the canned berries may be fairly uniform in size if the total score is not less than 80 points.

(c) "U. S. Grade C” or “U. S. Standard” is the quality of canned berries that possess similar varietal characteristics; that possess a fairly good color; that may be fairly uniform in size; that are fairly free from defects; that possess a fairly good character; that possess a normal flavor and odor; and that when scored in accordance with the scoring system outlined in this subpart, the total score is not less than 70 points.

(d) “Substandard" is the quality of canned berries that fail to meet the requirements of U. S. Grade C or U. S. Standard. LIQUID MEDIA, FILL OF CONTAINER, AND

DRAINED WEIGHTS $ 52.553 Recommended designations of

liquid media and Brix measurements

for canned berries. "Cut-out" requirements for liquid media in canned berries are not incorporated in the grades of the finished product since sirup or any other liquid medium, as such, is not a factor of quality for the purpose of these grades. The recommended "cut-out" Brix measurement, as applicable, for the respective designations are as follows: Designations of Liquid Media and Brit

Measurements "Extra heavy sirup": 24° or more, but not more than 35o Brix.

"Heavy sirup": 19° or more, but less than 24° Brix.

"Light sirup": 14° or more, but less than 19° Brix.

"Slightly sweetened water": Less than 14° Brix.

"In water”: Packed in water.

8 52.554 Recommended fill of

tainer. The recommended fill of container is not incorporated in the grades of the finished product since fill of container, as such, is not a factor of quality for the purpose of these grades. It is recommended that each container of canned berries be filled with berries as full as practicable without impairment of quality and that the product and packing medium occupy not less than 90 percent of the volume of the container. $ 52.555 Recommended minimum

drained weight. The minimum drained weight recommendations are not incorporated in the grades of the finished product since drained weight, as such, is not a factor of quality for the purpose of these grades. The drained weight of canned berries is determined by emptying the contents upon a United States Standard No. 8 circular sieve of proper diameter containing 8 meshes to the inch (0.0937 inch, 53%, square openings) so as to distribute the product evenly, inclining the sieve slightly to facilitate drainage, and allowing to drain for two minutes. The drained weight (or drained berries) is the weight of the sieve and the berries less the weight of the dry sieve. A sieve 8 inches in diameter is used for the equivalent of No. 3 size cans (404 X 414) and smaller, and a sieve 12 inches in diameter is used for containers larger than the equivalent of the No. 3 size can. $ 52.556 Compliance with recom

mended drained weights. Compliance with the recommended drained weights for canned berries 18 determined by averaging the drained weights from all containers which are representative of a specific lot and such lot is considered as meeting the recommendations, if: The averaged drained weight from all the containers meets the recommended drained weight; onehalf or more of the containers meet the recommended drained weight; and the drained weights from the containers which do not meet the recommended drained weight are within the range of variability for good commercial practices.

water. Water pack (packed in

water).

(b) “Brix" means the de rees Brix of the liquid from canned blueberries when tested with a Brix hydrometer calibrated at 20 degrees C. (68 degrees F.). If the liquid is tested at a temperature other than 20 degrees C. (68 degrees F.) the applicable temperature correction shall be made to the reading of the scale as prescribed in the "Oficial Methods of

Analysis of the Association of Oficial Agricultural Chemists.” The degrees Brix of the liquid from canned blueberries may be determined by any other method which gives equivalent results. $ 52.585 Recommended fill of

container. The recommended fill of container is not incorporated in the grades of the finished product since fill of container, as such, is not a factor of quality for the purpose of these grades. It is recommended that each container of canned blueberries be filled with blueberries as full as practicable without impairment of quality and that the product and packing medium occupy not less than 90 percent of the volume of the container. $ 52.586 Recommended minimum

drained weight. The minimum drained weight recommendations are not incorporated in the grades of the finished product since drained weight, as such, is not a factor of quality for the purpose of these grades. The drained weight of canned blueberries is determined by emptying the contents of the container upon a United States Standard No. 8 circular sieve of proper diameter containing 8 meshes to the inch (0.0937inch, +3%, square openings) so as to distribute the product evenly, inclining the sieve slightly to facilitate drainage, and allowing to drain for two minutes. The drained weight (or drained blueberries) is the weight of the sieve and the blueberries less the weight of the dry sieve. A sieve 8 inches in diameter is used for the equivalent of No. 3 size cans (404 x 414) and smaller, and a sieve 12 inches in diameter is used for containers larger than the equivalent of the No. 3 size can.
