(a) U.S. Grade A (or U.S. Fancy) is the quality of frozen broccoli that:

(1) Meets the following prerequisites (with deviants as specified in § 52.641 (a));

(i) Has similar varietal characteristics;

(ii) Has a good flavor and odor; (iii) Is practically free from grit or silt;

(iv) Has a good, bright, overall color appearance;

(v) With respect to the styles of cuts, chopped, and pieces; has individual buds that are at least reasonably well developed; and

(2) Meets the requirements for the various quality factors in Table V (or V Alternate), VI, VII as applicable for the style.

(b) U.S. Grade B or (U.S. Extra Standard) is the quality of frozen broccoli that:

(1) Meets the following prerequisites (with deviants as specified in § 52.641 (a));

(i) Has similar varietal characteristics;

(ii) Has at least a fairly good flavor and odor;

(iii) Has no more than a trace of grit

or silt;

(iv) Has at least a reasonably good overall color appearance which may be slightly dull;

(v) With respect to the styles of cuts, chopped, or pieces; may have poorly developed buds that do not materially affect the appearance of the product; and

(2) Meets requirements for the various quality factors in Table V (or V Alternate), VI, or VII as applicable for the style.

(c) Substandard is the quality of frozen broccoli that fails to meet the requirements for U.S. Grade B.

§ 52.637 Factors of quality and grade compliance.

(a) The grade of a lot of frozen broccoli is based on compliance with the prerequisites specified in § 52.636 and with requirements for the following quality factors:

(1) Color;

(2) Uniformity of size;

(3) Detached fragments;

(4) Loose leaves or pieces of leaves; (5) Damaged; broken; blemished; (6) Trimming, with respect to the styles of spears and short spears; (7) Development; (8) Fiber; and

(9) Harmless extraneous material.

AND LOT COMPLIANCE

§ 52.638 Sample size.

(a) General. The sample size to determine compliance with requirements of these standards shall be specified in the sampling plans and procedures in the "Regulations Governing Inspection of Processed Fruits and Vegetables and Related Products (§§ 52.1-52.83), for Lot Inspection or On-Line-Inspection, as applicable.

(b) Deviants. The acceptance numbers for deviants specified in the sampling plans cited in paragraph (a) of this section apply only to the prerequisite factors specified for the grade in § 52.636. They do not apply to the quality factors covered by the sampling plans in § 52.637.

§ 52.639 Determining proportions of head material and leaf material. (a) Method. The percent, by weight, of head material and leaf material in

cut and chopped broccoli may be determined as follows:

(1) Equipment needed.

(i) 250 ml beaker.

(ii) Gram scale, or other suitable scale graduated to 0.1 ounce.

(iii) Laboratory tweezers, scalpel, or other instrument suitable for separating the stem material, leaf material, and head material.

(iv) Flat grading tray.

(2) Procedure.

(i) Thoroughly mix sample unit to be tested if sample unit is not the entire contents of the container.

(ii) Weigh approximately 50 grams (134 ounces) in the case of chopped product in a previously tarred 250 ml beaker.

(iii) In the case of cut style weigh 283 grams (10 ounces) of product in a suitable previously tarred container.

(iv) Spread the weighed product out on a flat grading tray.

(v) Separate the stem material from the head and leaf material; weigh the stem material, and record.

(vi) Separate the leaf material from the head material; weigh each separately and record.

(vii) The weight of the head material 'divided by the sum of the weights of the stem, head, and leaf materials multiplied by 100 is the percent, by weight, of head material.

(viii) The weight of leaf material divided by the sum of the weights of the stem, head, and leaf materials multiplied by 100 is the percent, by weight, of leaf material.

§ 52.640 Lot acceptance for style.

(a) Spears; short spears. A lot of frozen broccoli is considered as meeting the style requirements for spears or short spears as applicable, if the defects permitted and the AL value specified in Table I or Table I Alternate are not exceeded.

(b) Cuts; chopped.

(1) Head material; Leaf material-A lot of frozen broccoli is considered as meeting the style requirements for cuts or chopped for head material and leaf material; Provided, That:

(i) The average of all the sample units in the sample does not exceed 25 percent, by weight, of leaf material; and

(ii) The average of all the sample units in the sample is not less than 25 percent, by weight, of head material; and

(iii) No single sample unit contains less than 15 percent by weight, of head material, or more than 35 percent, by weight, of leaf material.

(2) Length-The AL values and/or the cumulative acceptance numbers for the defects permitted, specified in Table II or III as applicable, are not exceeded. § 52.641 Lot acceptance for quality.

A lot of frozen broccoli is considered as meeting the requirements for quality if: (a) The number of deviants for the prerequisites specified for the applicable grade in § 52.636 does not exceed the acceptance number specified in the sampling plans in the "Regulations Governing Inspection of Processed Fruits and Vegetables and Related Products" (§§ 52.1-52.83); and

(b) The AL values and/or the cumulative acceptance numbers for the defects permitted for the applicable defect classifications specified in Tables V (or V Alternate), VI, and VII are not exceeded.
