Grades of Canned Succotash SOURCE: $ 52.6001 to 52.6009 appear at 32 F.R. 7580, May 24, 1967, unless otherwise noted.

PRODUCT DESCRIPTION, GRADES

[blocks in formation]
[blocks in formation]

U.S. Grade C or U.S. Standard canned succotash consists of cream-style or whole-grain sweet corn and lima or snap beans which meet the requirements of U.S. Grade C or U.S. Standard for the respective canned or frozen commodities. If tomatoes are an ingredient, they must meet the requirements of U.S. Grade C canned tomatoes for color and absence of defects.

§ 52.6005 Grade D or Substandard.

Grade D or Substandard canned succotash is succotash that fails to meet the requirements of U.S. Grade C or U.S. Standard.

PROPORTION OF INGREDIENTS

§ 52.6006 Proportion of ingredients.

(a) Federal certificates of grade shall indicate the approximate percentage of ingredients found upon examination. If whole-grain style corn is an ingredient, the percentage of ingredients shall be based on drained weight; otherwise, the percentage of ingredients shall be based on net weight.

(b) The following mixtures of vegetables in canned succotash shall conform with the proportions indicated in Table No. I:

Cream-style corn and snap beans.

Cream-style corn and lima beans (fresh or frozen).

Cream-style corn and lima beans (dry, "soaked")

Cream-style corn, snap beans, and to

matoes.

Cream-style corn, lima beans (fresh or frozen), and tomatoes.

FILL OF CONTAINER, DRAINED WEIGHT

METHOD

§ 52.6007 Recommended fill of container.

The container shall be filled with succotash as full as practicable without impairment of quality. The product and packing medium shall occupy not less than 90 percent of the total volume capacity of the container.

§ 52.6008 Method for ascertaining drained weight.

Drained weights of canned succotash containing whole-grain corn are determined by emptying the contents of the container upon a circular sieve of proper diameter, containing eight meshes to the inch (0.097-inch perforations) and allowing to drain for 2 minutes. A sieve 8 inches in diameter is used for No. 22 cans and smaller, and a sieve 12 inches in diameter is used for No. 10 cans.
