§ 133.148   Hard grating cheeses.

　　（a） The cheeses for which definitions and standards of identity are prescribed by this section are hard grating cheeses for which specifically applicable definitions and standards of identity are not prescribed by other sections of this part. They are made from milk and the other ingredients specified in this section, by the procedure set forth in paragraph （b） of this section. They contain not more than 34 percent of moisture, and their solids contain not less than 32 percent of milkfat, as determined by the methods prescribed in §133.5 （a）, （b）, and （d）. Hard grating cheeses are cured for not less than 6 months.

　　（b） Milk, which may be pasteurized or clarified or both, and which may be warmed, is subjected to the action of harmless lactic-acid-producing bacteria or other harmless flavor-producing bacteria, present in such milk or added thereto. Sufficient rennet, rennet paste, extract of rennet paste, or other safe and suitable milk-clotting enzyme that produces equivalent curd formation, singly or in any combination （with or without purified calcium chloride in a quantity not more than 0.02 percent, calculated as anhydrous calcium chloride, of the weight of the milk） is added to set the milk to a semisolid mass. Harmless artificial coloring may be added. The mass is cut into small particles, stirred, and heated. The curd is separated from the whey, drained, shaped into forms, pressed, salted, and cured. The rind may be colored or rubbed with vegetable oil or both. A harmless preparation of enzymes of animal or plant origin capable of aiding in the curing or development of flavor of hard grating cheese may be added during the procedure, in such quantity that the weight of the solids of such preparation is not more than 0.1 percent of the weight of the milk used.

　　（c） For the purposes of this section, the word “milk” means cow's milk or goat's milk or sheep's milk or mixtures of two or all of these. Such milk may be adjusted by separating part of the fat therefrom or （in the case of cow's milk） by adding one or more of the following: Cream, skim milk, concentrated skim milk, nonfat dry milk; （in the case of goat's milk） the corresponding products from goat's milk; （in the case of sheep's milk） the corresponding products from sheep's milk; water in a quantity sufficient to reconstitute any such concentrated or dried products used.

　　（d） Safe and suitable antimycotic agent（s）, the cumulative levels of which shall not exceed current good manufacturing practice, may be added to the surface of the cheese.

　　（e） The name of each hard grating cheese for which a definition and standard of identity is prescribed by this section is “Hard grating cheese”， preceded or followed by:

　　（1） The specific common or usual name of such hard grating cheese, if any such name has become generally recognized therefor; or

　　（2） If no such specific common or usual name has become generally recognized therefor, an arbitrary or fanciful name that is not false or misleading in any particular.

　　（3） When milk other than cow's milk is used, in whole or in part, the statement “made from ___”， the blank being filled in with the name or names of the milk used, in order of predominance by weight.

　　（f） 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, except that:

　　（1） When milk other than cow's milk is used, in whole or in part, the common or usual name of each such milk ingredient shall be declared in order of predominance by weight; and

　　（2） Enzymes of the animal, plant, or microbial origin may be declared as “enzymes”。
