21 C.F.R. § 155.120
(2) Optional color and varietal types and styles of pack. The optional color and varietal types and styles of the bean ingredient referred to in paragraph (a)(1) of this section are:
(ii) Optional varietal types—(a) Round. Beans having a width not greater than 1 1/2 times the thickness of the bean; or
(b) Flat. Beans having a width greater than 1 1/2 times the thickness of the bean.
(iii) Optional styles of pack—(a) Whole. Whole pods of any length.
(b) Shoestring or sliced lengthwise or French style. Pods sliced lengthwise.
(c) Cuts. Transversely cut pods not less than 19 mm (0.75 in) long as measured along the longitudinal axis, which may contain the shorter end pieces that result from cutting such pods.
(d) Short cuts. Pieces of pods cut transversely of which 75 percent, by count, or more are less than 19 mm (0.75 in) in length and not more than 1 percent by count are more than 32 mm (1 1/4 in) in length.
(e) Diagonal cuts. Pods cut in lengths as specified in paragraph (a)(2)(iii)(c) of this section, except the pods are cut at an angle approximately 45° to the longitudinal axis.
(f) Diagonal short cuts. Pods cut in lengths as specified in paragraph (a)(2)(iii)(d) of this section, except the pods are cut at an angle approximately 45° to the longitudinal axis.
(g) Mixture. Any mixture of two or more of the styles specified in paragraph (a)(2)(iii)(a) to (f), inclusive, of this section.
(3) Optional ingredients. In addition to the optional packing media listed in paragraph (a)(1) of this section and the optional types and styles of beans ingredient listed in paragraph (a)(2) of this section, the following safe and suitable optional ingredients may be used:
(4) Labeling.
(ii) The following shall be included as part of the name or in conjunction with the name of the food:
(a) A declaration of any flavoring that characterizes the product as specified in § 101.22 of this chapter.
(b) A declaration of any spice, seasoning, or garnishing that characterizes the product, e.g., “with added spice”, or, in lieu of the word “spice”, the common name of the spice, e.g., “seasoned with green peppers”.
(c) The words “vacuum pack” or “vacuum packed” when the weight of the liquid in the container, as determined by the method prescribed in paragraph (b)(2)(i) of this section is not more than 25 percent of the net weight, and the container is closed under conditions creating a high vacuum in the container.
(d) The name of the optional style of bean ingredient as set forth in paragraph (a)(2)(iii) of this section or, if a product consists of a mixture of such styles, the words “mixture of ” the blank to be filled in with the names of the styles present, arranged in the order of decreasing predominance, if any, by weight of such ingredients. If the product consists of whole beans and the pods are packed parallel to the sides of the container, the word “whole” may be preceded or followed by the words “vertical pack”, or if the pods are cut at both ends and are of substantially equal lengths, the words “asparagus style” may be used in lieu of the words “vertical pack”. If the product consists of short cuts or diagonal short cuts, a numerical expression indicating the predominate length of cut in the finished food may be used in lieu of the word “short”, e.g., “ 1/2 inch cut”.
(iii) The following may be included in the name of the food:
(a) The word “stringless” where the beans are in fact stringless.
(b) The name of the optional varietal type as specified in paragraph (a)(2)(ii) of this section, or the specific varietal name, e.g., “Blue Lake Green Beans”, or both.
(b) Quality.
(1) When tested by the method prescribed in paragraph (b)(2) of this section:
(2) Canned beans shall be tested by the following method to determine whether they meet the requirements of paragraph (b)(1) of this section:
(iii) Examine the drained material in the tray, weigh and record weight of blemished units, count and record the number of unstemmed units; and, in case the material consists of the optional ingredient specified in paragraph (a)(2)(iii) (c), (d) or (f) of this section, count and record the number of units which are less than 13 mm (0.50 in.) long. If the number of units per 340 g (12 oz.) is 240 or less, divide the number of units which are less than 13 mm (0.50 in.) by the drained weight recorded in paragraph (b)(2)(i) of this section and multiply by 340 to obtain the number of such units per 340 g (12 oz.) drained weight. If the number of units per 340 g (12 oz.) exceeds 240, divide the number of units less than 13 mm (0.50 in.) long by the total number of units and multiply by 100 to determine the percentage by count of the total units which are less than 13 mm (0.50 in.) long.
(a) Divide the weight of blemished units by the drained weight recorded in paragraph (b)(2)(i) of this section and multiply by 100 to obtain the percentage by weight of blemished units in the container.
(b) Divide the number of unstemmed units by the drained weight recorded in paragraph (b)(2)(i) of this section and multiply by 340 to obtain the number of unstemmed units per 340 g (12 oz.) of drained weight.
(vii) If strings have been removed for testing, as prescribed in paragraph (b)(2)(vi) of this section, test them as follows:
Fasten clamp, weighted to 250 g (8.8 oz.), to one end of the string, grasp the other end with the fingers (a cloth may be used to aid in holding the string), and lift gently. Count the string as tough if it supports the 250 g (8.8 oz.) weight for at least 5 seconds. If the string breaks before 5 seconds, test such parts into which it breaks as are 13 mm ( 1/2 in.) or more in length; and if any such part of the string supports the 250 g (8.8 oz.) weight for at least 5 seconds, count the string as tough. Divide the number of tough strings by the weight of the sample recorded in paragraph (b)(2)(v) of this section and multiply by 340 to obtain the number of tough strings per 340 g (12 oz.) drained weight.
(viii) Combine the deseeded pods with the trimmings reserved in paragraph (b)(2)(vi) of this section, and, if strings were tested as prescribed in paragraph (b)(2)(vii) of this section, add such strings broken or unbroken. Weigh and record weight of combined material. Transfer to the metal cup of a malted-milk stirrer and mash with a pestle. Wash material adhering to the pestle back into cup with 200 cc of boiling water. Bring mixture nearly to a boil, add 25 cc of 50 percent (by weight) sodium hydroxide solution and bring to a boil. (If foaming is excessive, 1 cc of capryl alcohol may be added.) Boil for 5 minutes, then stir for 5 minutes with a malted-milk stirrer capable of a no-load speed of at least 7,200 rpm. Use a rotor with two scalloped buttons shaped as shown in exhibit 1 as follows:

Transfer the material from the cup to a previously weighed 30-mesh monel metal screen having a diameter of about 9-10 cm (3 1/2 to 4 in.) and side walls about 2.5 cm (1 in.) high, and wash fiber on the screen with a stream of water using a pressure not exceeding a head (vertical distance between upper level of water and outlet of glass tube) of 152 cm (60 in.), delivered through a glass tube 7.6 cm (3 in.) long and 3 mm ( 1/8 in.) inside diameter inserted into a rubber tube of 6 mm ( 1/4 in.) inside diameter. Wash the pulpy portion of the material through the screen and continue washing until the remaining fibrous material, moistened with phenolphthalein solution, does not show any red color after standing 5 minutes. Again wash to remove phenolphthalein. Dry the screen containing the fibrous material for 2 hours at 100 °C, cool, weigh, and deduct weight of screen. Divide the weight of fibrous material by the weight of combined deseeded pods, trimmings, and strings and multiply by 100 to obtain the percentage of fibrous material.
(4) If the quality of the canned green beans or canned wax beans falls below the standard of quality prescribed by paragraph (b)(1) of this section, the label shall bear the general statement of substandard quality specified in § 130.14(a) of this chapter, in the manner and form therein specified; but in lieu of the words prescribed for the second line inside the rectangle the following words may be used, when the quality of canned green beans or canned wax beans falls below the standard in one only of the following respects:
