§ 52.2044 Types of packs of canned sweetpotatoes.

In addition to styles, canned sweetpotatoes are usually processed as any one of the following types of packs:

(a) In a liquid packing medium.

(b) "Vacuum-pack (without packing media)."

(c) "Solid-pack" (or "dry-pack"). § 52.2045 Grades of canned sweetpota

toes.

(a) "U.S. Grade A" or "U.S. Fancy" is the quality of canned sweetpotatoes that possess a good color; that are practically uniform in shape and size or possess good consistency, as applicable; that are practically free from defects; that possess a good character; that possess a normal flavor and odor; and that score not less than 85 points when scored in accordance with the scoring system outlined in this subpart.

(b) "U. S. Grade C" or "U. S. Standard" is the quality of canned sweetpotatoes 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 are of such quality with respect to shape and size or consistency as to score not less than 70 points when scored in accordance with the scoring system outlined in this subpart.

(c) "U.S. Grade D" or "Substandard" is the quality of canned sweetpotatoes that fail to meet the requirements of "U. S. Grade C" or "U. S. Standard."

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 purposes of these grades. It is recommended that each container be filled as full as practicable with sweetpotatoes and that the product and packing medium, if any, occupy not less than 90 percent of the volume of the container. § 52.2048 Recommended minimum drained weight.

(a) The minimum drained weight recommendations in Table I of this section are not incorporated in the grades of the finished product since drained weight, as such, is not a factor of quality for the purposes of these grades.

(b) The drained weight recommendations in Table I of this section are not applicable to canned sweetpotatoes packed as "vacuum-pack (without packing media)" or as "solid-pack" (or "dry-pack").

(c) The drained weight of canned sweetpotatoes 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 (0.0937-inch±3%, square openings) so as to distribute the product evenly, inclining the sieve

acteristic color (either yellow or golden) and that there may be reasonable variations of such characteristic color in the units, in each unit, or in the mass.

(b) (C) classification. If the canned sweetpotatoes possess a fairly good color, a score of 14 to 16 points may be given. Canned sweetpotatoes 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 color may be variable in the units, in each unit, or in the mass and that the color may be slightly dull but is not offcolor.

(c) (SStd) classification. Canned sweetpotatoes that fail to meet the requirements of paragraph (b) 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).

§ 52.2052

Shape and size or consistency.

(a) (A) classification. Whole and pieces (whether packed singly or in combination) packed in a liquid packing medium or as "vacuumpack (without packing media)" that are practically uniform in shape and size may be given a score of 17 to 20 points; and canned sweetpotatoes packed as "solid-pack" (or "dry-pack") that possess a good consistency may be given a score of 17 to 20 points. "Practically uniform in shape and size" and "good consistency" have the following meanings with respect to the following styles and types of packs of canned sweetpotatoes:

(1) Whole and pieces (whether packed singly or in combination) in a liquid packing medium or “vacuum-pack (without packing media)." "Practically uniform in shape and size" means that the units of a single style may vary moderately in shape and that the weight of the largest unit, irrespective of style, is not more than three times the weight of the second smallest unit, irrespective of style.

(2) Whole, pieces, and mashed (whether packed singly or in combination) packed as "solid-pack” (or “drypack"). "Good consistency" means that the sweetpotatoes possess a stiff consistency which may show a slight separation of free liquid.

(b) (C) classification. If whole and pieces (whether packed singly or in combination) packed in a liquid packing me

dium or as "vacuum-pack (without packing media)" are fairly uniform in shape and size, a score of 14 to 16 points may be given; or if the canned sweetpotatoes packed as "solid-pack" (or "dry-pack") possess a fairly good consistency, a score of 14 to 16 points may be given. Canned sweetpotatoes 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 uniform in shape and size" and "fairly good consistency" have the following meanings with respect to the following styles and types of packs of canned sweetpotatoes:

(1) Whole and pieces (whether packed singly or in combination) in a liquid packing medium or “vacuum-pack (without packing media)." "Fairly uniform in shape and size" means that the units of a single style may vary considerably in shape and that the weight of the largest unit, irrespective of style, is not more than four times the weight of the second smallest unit, irrespective of style.

(2) Whole, pieces, and mashed (whether packed singly or in combination) packed as "solid-pack (or "drypack"). "Fairly good consistency" means that the sweetpotatoes possess a thick consistency but may not be free flowing.

(c)

(SStd) classification. Canned sweetpotatoes that fail to meet the requirements of paragraph (b) of this section may be given a score of 0 to 13 points and 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).

(a) General. The factor of absence of defects refers to the degree of freedom from particles of peel, secondary rootlets, untrimmed fibrous ends, discolored areas, or from other defects.

(b) (A) classification. Canned sweetpotatoes that are practically free from defects may be given a score of 34 to 40 points. "Practically free from defects" means that the product contains not more than a slight amount of particles of peel, secondary rootlets, untrimmed fibrous ends, discolored areas, or other defects which do not affect materially the appearance or the edibility of the product.

(c) (C) classification. If the canned sweetpotatoes are fairly free from de

fects, a score of 28 to 33 points may be given. Canned sweetpotatoes 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 particles of peel, secondary rootlets, untrimmed fibrous ends, discolored areas, or other defects may be definitely noticeable but are not so prominent as to affect seriously the appearance or the edibility of the product.

(d) (SStd) classification. Canned sweetpotatoes that fail to meet the requirements of paragraph (c) of this section may be given a score of 0 to 27 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).

(a) General. The factor of character refers to the texture and condition of the flesh, the degree of freedom from tough or coarse fibers, the tenderness of the canned sweetpotatoes, and the tendency of sweetpotatoes packed in a liquid packing medium or as "vacuum-pack (without packing media)" to retain their apparent original conformation and size without disintegration.

(b) (A) classification. Canned sweetpotatoes that possess a good character may be given a score of 17 to 20 points. "Good character" has the following meanings with respect to the following styles and types of packs of canned sweetpotatoes:

(1) Whole and pieces (whether packed singly or in combination) in a liquid packing medium or "vacuum-pack (without packing media)." "Good character" means that the units possess a uniformly smooth texture, are practically free from tough or coarse fibers, and may be soft to firm but hold their apparent original conformation and size without material distintegration.

(2) Whole, pieces, and mashed packed as "solid-pack” (or “dry-pack”). "Good character" means that any units present possess a uniformly smooth texture, are practically free from tough or coarse fibers, and may be soft to firm and that any mashed sweetpotatoes present possess a uniformly smooth texture, practically free from tough or coarse fibers.
