(a) Active Dry Yeast is yeast which has been dried in such a manner as to preserve a large portion of its fermenting power. It must contain no added cereal or filler and must contain not less than 15 billion live yeast cells per gram.(b) Brewers Dried Yeast is the dried, non-fermentative, non-extracted yeast of the botanical classification Saccharomyces resulting as a by-product from the brewing of beer and ale. It must contain not less than 35 percent crude protein. It must be labeled according to its crude protein content.(c) Brewers Liquid Yeast is the non-fermentative, non-extracted yeast of the botanical classification Saccharomyces resulting as a by-product from the brewing of beer and ale. It must contain not less than 35 percent crude protein on a dry weight basis. The guaranteed analysis shall include the maximum moisture.(d) Grain Distillers Dried Yeast is the dried, non-fermentative yeast of the botanical classification Saccharomyces resulting from the fermentation of grains and yeast, separated from the mash, either before or after distillation. It must contain not less than 40 percent crude protein.(e) Hydrolyzed Yeast is a concentrated, non-extracted, partially soluble, yeast digest. Solubilization is accomplished by enzymatic hydrolysis of whole Saccharomyces cerevisiae cells. Salts may be added as processing aids in accordance with good manufacturing practices. It must not contain less than 35 percent crude protein.(f) Irradiated Dried Yeast, Irradiated [Specify] Dried Yeast is the dried, non-fermentative yeast which has been subjected to ultraviolet rays in order to produce anti-rachitic potency. When Irradiated Dried Yeast or Irradiated [Specify] Dried Yeast is used as an ingredient of proprietary feeds for four-footed animals, the name may be followed by a parenthetical phrase (Source of Vitamin D2).(g) Molasses Hydrolyzed Yeast is a concentrated, non-extracted, partially soluble yeast digest. Yeast cells are sourced from the fermentation of molasses for ethanol production. Solubilization is accomplished by enzymatic hydrolysis of whole Saccharomyces cerevisiae cells. Salts may be added as processing aids in accordance with good manufacturing practices. It must not contain less than 30 percent crude protein.(h) Molasses Yeast Condensed Solubles is obtained by condensing to a syrup consistency the broth remaining after the removal of baker's yeast cells propagated on molasses.(i) Primary Dried Yeast or Dried Yeast is the dried, non-fermentative yeast of the botanical classification Saccharomyces which has been separated from the medium in which propagated. It must consist of yeast cells with no fillers and contain not less than 40 percent crude protein.(j) Scheffersomyces stipitis Dried Yeast is the dried, non-viable yeast of the botanical classification Scheffersomyces stipitis that has been grown on thin stillage from the ethanol production process from the fermentation of a grain or grain mixture, and is separated by centrifugation from the media on which it was propagated. The product is produced in accordance with good manufacturing practices to control the potential for mycotoxin and other contaminants. The product is intended as a source of protein in cattle, sheep, goat, and swine feeds at levels up to 15 percent. It must contain not less than 40 percent crude protein. The label shall include guarantees for minimum crude protein and crude fat and maximum sulfur contents. Non-protein nitrogen content must be guaranteed when added.(k) Torula Dried Yeast or Candida Dried Yeast is the dried, non-fermentative yeast of the botanical classification (torulopsis) Candida utilis (formerly Torulopsis utilis) which has been separated from the medium in which propagated. It must contain not less than 40 percent crude protein.(l) Yeast Culture is the dried product composed of yeast (Saccharomyces cerevisiae and/or Kluyveromyces marxianus) and the media on which it was grown, dried in such a manner as to preserve the fermenting activity of the yeast. The media must be stated on the label. No reference to media in main ingredient listing is required when yeast culture forms a component of a proprietary mixed feed.(m) Yeast Extract is the concentrated solubles of mechanically ruptured cells of a selected strain of the yeast, Saccharomyces cerevisiae. It may be dried or concentrated. It must contain not less than nine (9) percent crude protein.Cal. Code Regs. Tit. 3, § 2809
