21 CFR 158.170 - Frozen peas.
prev | next
(1) Product definition. Frozen peas is the food in “package” form as that term is defined in § 1.20 of this chapter, prepared from the succulent seed of the pea plant of the species Pisum sativum L. Any suitable variety of pea may be used. It is blanched, drained, and preserved by freezing in such a way that the range of temperature of maximum crystallization is passed quickly. The freezing process shall not be regarded as complete until the product temperature has reached −18 °C (0 °F) or lower at the thermal center, after thermal stabilization. Such food may contain one, or any combination of two or more, of the following safe and suitable optional ingredients:
(2) Size specifications. If size graded, frozen peas shall contain not less than 80 percent by weight of peas of the size declared or of smaller sizes. The sample unit may not contain more than 20 percent by weight of peas of the next two larger sizes, of which not more than one quarter by weight of such peas may be of the larger of these two sizes, and may contain no peas larger than the next two larger sizes, if such there be. The following sizes and designations shall apply:
|Size designation||Round hole sieve size through which peas will pass|
|Extra small||Up to 7.5||0.295|
|Very small||Up to 8.2||.32|
|Small||Up to 8.75||.34|
|Medium||Up to 10.2||.40|
(3) Labeling. The name of the product is “peas”. The term “early”, “June”, or “early June” shall precede or follow the name in the case of smooth-skin or substantially smooth-skin peas, such as Alaska-type peas. Where the peas are of sweet green wrinkled varieties, the name may include the designation “sweet”, “green”, “wrinkled”, or any combination thereof. The label shall contain the words “frozen” or “quick frozen”. The name of the food shall include a declaration of any flavoring that characterizes the product as specified in § 101.22 of this chapter and a declaration of any condiment such as spices and mint leaves that characterizes the product, e.g., “Spice added”. Where a statement of pea size is made, such statement shall indicate either the size designation as specified in paragraph (a)(2) of this section or the applicable sieve size. However, the optional descriptive words “petite” or “tiny” may be used in conjunction with the product name when an average of 80 percent or more of the peas will pass through a circular opening of a diameter of 8.75 mm (0.34 in) or less for sweet green wrinkled peas and 8.2 mm (0.32 in) for smooth-skin or substantially smooth-skin peas, such as Alaska-type peas.
(4) Label declaration. Each of the ingredients used in the food shall be declared on the label as required by the applicable sections of parts 101 and 130 of this chapter.
(iii) Not more than 2 percent by weight seriously blemished peas, i.e., peas that are hard, shrivelled, spotted, discolored or otherwise blemished to an extent that the appearance or eating quality is seriously affected.
(iv) Not more than 15 percent by weight pea fragments, i.e., portions of peas, separated or individual cotyledons, crushed, partial or broken cotyledons and loose skins, but excluding entire intact peas with skins detached;
(v) Not more than 0.5 percent by weight, or more than 12 sq cm (2 sq in) in area, extraneous vegetable material, i.e., vine or leaf or pod material from the pea plant or other such material per sample unit as defined in paragraph (b) of this section.
(vi) The sum of the pea material described in paragraphs (b)(1) (i), (ii), (iii), and (iv) of this section shall not exceed 15 percent.
(vii) For peas that meet the organoleptic and analytical characteristics of sweet green wrinkled varieties:
(a) The alcohol-insoluble solids may not be more than 19 percent based on the procedure set forth in paragraph (b)(3) of this section.
(b) Not more than 15 percent by count of the peas may sink in a solution containing 16 percent salt by weight according to the brine flotation test set forth in paragraph (b)(4) of this section;
(viii) For smooth-skin or substantially smooth-skin varieties the alcohol insoluble solids may not be more than 23 percent based on the procedure set forth in paragraph (b)(3) of this section.
(ix) The quality of a lot shall be considered acceptable when the number of defectives does not exceed the acceptance number in the sampling plans set forth in § 158.3(f).
(2) The sample unit for determining compliance with the requirements of paragraph (b)(1) of this section other than those of paragraphs (b)(1)(vii)(a) and (b)(1)(viii) of this section, shall be 500 g (17.6 oz). For the determination of alcohol-insoluble solids as specified in paragraph (b)(3) of this section, the container may be the sample unit.
(a) One hundred parts of ethanol denatured with five parts of methanol volume to volume (formula 3A denatured alcohol), or
(b) A mixture of 95 parts of formula 3A denatured alcohol and five parts of isopropanol v/v.
(ii) Eighty percent alcohol (8 liters of extracting solutions, specified in paragraph (b)(3)(i) (a) or (b) of this section, diluted to 9.5 liters with water).
(v) Procedure—Transfer frozen contents of package to plastic bag; tie bag securely and immerse in water bath with continuous flow at room temperature. Avoid agitation of bag during thawing by using clamps or weights. When sample completely thaws, remove bag, blot off adhering water, and transfer peas to U.S. No. 8 sieve, using (20 cm.) size for container of less than 3 lb. net weight and (30.5 cm.) for larger quantities. Without shifting peas, incline sieve to aid drainage, drain 2 minutes. With cloth wipe surplus water from lower screen surface. Weigh 250 g. of peas into high-speed blender, add 250 g. of water and blend to smooth paste. For less than 250 g. sample, use entire sample with equal weight of water. Weight 20 g.±10 mg. of the paste into 250 ml. distillation flask, add 120 ml. of extracting solutions specified in paragraph (b)(3)(i) (a) or (b) of this section, and reflux 30 minutes on steam or water bath or hotplate. Fit into a buchner funnel a filter paper of appropriate size (previously prepared by drying in flatbottom dish for 2 hours in drying oven, covering, cooling in desiccator, and weighing). Apply vacuum to buchner funnel and transfer contents of beaker so as to avoid running over edge of paper. Aspirate to dryness and wash material on filter with 80 percent alcohol until washings are clear and colorless. Transfer paper and alcohol-insoluble solids to drying dish used to prepare paper, dry uncovered for 2 hours in drying oven, cover, cool in desiccator, and weigh at once. From this weight deduct weight of dish, cover, and paper. Calculate percent by weight of alcohol-insoluble solids.
(i) Explanation—The brine flotation test utilizes salt solutions of various specific gravities to separate the peas according to maturity. The brine solutions are based on the percentage by weight of pure salt (NaCl) in solution at 20 °C. In making the test the brine solutions are standardized to the proper specific gravity equivalent to the specified “percent of salt solutions at 20 °C” by using a salometer spindle accurately calibrated at 20 °C. A 250 ml glass beaker or similar receptacle is filled with the brine solution to a depth of approximately 50 mm. The brine solution and sample (100 peas per container) must be at the same temperature and should closely approximate 20 °C.
(ii) Procedure—After carefully removing the skins from the peas, place the peas into the solution. Pieces of peas and loose skins should not be used in making the brine flotation test. If cotyledons divide, use both cotyledons in the test and consider the two separated cotyledons as 1 pea; and, if an odd cotyledon sinks, consider it as one pea. Only peas that sink to the bottom of the receptacle within 10 seconds after immersion are counted as “peas that sink”.
(5) If the quality of the frozen peas falls below the standard prescribed in paragraph (b)(1) of this section, the label shall bear the general statement of substandard quality specified in the Code of Federal Regulations but in lieu of the words prescribed in the second line of the rectangle the following words may be used where the frozen peas fall below the standard in only one respect: “Below standard in quality ___”, the blank to be filled in with the specific reason for substandard quality as listed in the standard.
