§133.164 纽伏特干�?Nuworld cheese)

　　（a� De scription. �?� Nuworld cheese is the food prepared by the procedure set forth in paragraph （a）（2� of this section or by any other procedure which produces a finished cheese having the same physical and chemical properties. It is characterized by the presence of creamy-white mold, a white mutant of Penicillium roquefortii, throughout the cheese. The minimum milkfat content is 50 percent by weight of the solids and the maximum moisture content is 46 percent by weight, as determined by the methods described in ��133.5. The dairy ingredients used may be pasteurized. Nuworld cheese is at least 60 days old.

　　�?� One or more of the dairy ingredients specified in paragraph （b）（1� of this section may be warmed and is subjected to the action of a lactic acid-producing bacterial culture. One or more of the clotting enzymes specified in paragraph （b）（2� of this section is added to set the dairy ingredients to a semisolid mass. The mass is cut into smaller portions and allowed to stand for a time. The mixed curd and whey is placed into forms permitting further drainage. While being placed in forms, spores of a white mutant of the mold Penicillium roquefortii are added. The forms are turned several times during drainage. When sufficiently drained, the shaped curd is removed from the forms and salted with dry salt or brine. Perforations are then made in the shaped curd and it is held at a temperature of approximately 50 ��F at 90 to 95 percent relative humidity, until the characteristic mold growth has developed. During storage, the surface of the cheese may be scraped to remove surface growth of undesirable microorganisms. One or more of the other optional ingredients specified in paragraph （b）（3� of this section may be added during the procedure.

　　（b� Optional ingredients. The following safe and suitable ingredients may be used:

　　�?� Dairy ingredients. Milk, nonfat milk, or cream, as defined in ��133.3, used alone or in combination.

　　�?� Clotting enzymes. Rennet and/or other clotting enzymes of animal, plant, or microbial origin.

　　�?� Other optional ingredients. （i� Blue or green color in an amount to neutralize the natural yellow color of the curd.

　　（ii� Calcium chloride in an amount not more than 0.02 percent （calculated as anhydrous calcium chloride� of the weight of the dairy ingredients, used as a coagulation aid.

　　（iii� Enzymes of animal, plant, or microbial origin, used in curing or flavor development.

　　（c� Nomenclature. The name of the food is ��nuworld cheese��、�/p>

　　（d� 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:
