TESTING OF MILK ON THE BASIS OF PROTEIN
Part 1525.2610 - PROCEDURE

Milk, which may be warmed or pasteurized or both and which may be clarified or homogenized or both, is mixed with an acidifying agent prescribed by part 1525.2640. Salt may also be added. Sufficient rennet (with or without purified calcium chloride in a quantity of not more than 0.02 percent, calculated as anhydrous calcium chloride, of the weight of the milk) may be added to set the milk. The mixture is heated until a temperature of about 180 degrees Fahrenheit is reached and it is held near that temperature until the curd separates. The curd is removed by skimming or the whey is drained or siphoned off. The curd is placed in perforated containers to permit further drainage. The containers may be placed in cold water for cooling. They are then removed from the water for further drainage. Additional curd may be obtained from the whey by the further addition of an acidifying agent prescribed by part 1525.2640 or by further heating or both. The curd may be whipped or beaten to obtain a finer texture.
