Canned mushrooms, as defined in the definitions and standards of identity for canned vegetables (21 CFR 51.990) issued pursuant to the Federal Food, Drug, and Cosmetic Act, means the product prepared from the sound, succulent, fresh mushroom by proper trimming, washing, and sorting and is packed with the addition of water in hermetically sealed containers and sufficiently processed by heat to assure preservation of the product. Salt, or monosodium glutamate, or both may be added in a quantity sufficient to season the product. Ascorbic acid (Vitamin C) may be added in a quantity not to exceed 37.5 milligrams for each ounce of drained weight of mushrooms.

Styles of canned mushrooms.

(a) Whole is the style of canned mushrooms that consists of the caps with attached stems which are more than 1/8 inch in length when measured from the underside of the cap to the cut end of the stem.

(b) Buttons is the style of canned mushrooms that consists of the caps with attached stems which are cut transversely below the veil so that in 85 percent or more, by count, of the units the attached stem when measured from the underside of the cap to the cut end of the stem does not exceed 1/8 inch in length; and in the remaining units none of the attached stems may be more than 1/4 inch in length.

(c) Sliced whole is the style of canned mushrooms that consists of units which have been sliced from whole mushrooms so that in 80 percent or more, by weight, of all the units the direction of the slice is approximately parallel to the longitudinal axis of the stem; and not more than 5 percent, by weight of all the units may be detached portions of stems.

(d) Random sliced whole is the style of canned mushrooms that consists of units which have been sliced from whole mushrooms in a random manner so that the direction of the slice may materially deviate from approximately parallel to the longitudinal axis of the stem; and not more than 15 percent, by weight of all the units may be detached portions of stem.

(e) Sliced buttons is the style of canned mushrooms that consists of units which have been sliced from button mushrooms so that in 90 percent or more, by weight, of all the units the direction of the slice is approximately parallel to the longitudinal axis of the stem.
