Cottage cheese is a concentrated processing of semi-finished yogurt, which is a fresh cheese. The craftsmanship is unique in that it heats the milk at a higher temperature and uses the yogurt strain as a starter to solidify the milk, which is then prepared according to the traditional cheese making method. Compared with yogurt, cottage cheese contains less water (75% to 80%) and more protein (12% to 15%) and contains a large amount of active lactic acid bacteria.

Operation points
Raw milk acceptance and heat treatment
Raw milk must be fresh, free of undesirable flavors, free of antibiotics and other impurities. The grease content is required to be 3%, and the total milk solids content is not less than 8.5%. The qualified raw milk is pasteurized, heated at a temperature of 80 ° C to 85 ° C, and cooled to 45 ° C.
curd
The starter was added to the raw milk cooled to the inoculation temperature in a ratio of 3%, stirred uniformly, and fermented at a temperature of 42 ° C for 2.5 hours to 3 hours, and when the pH was 4.6, a curd was formed.
Coagulum recovery
After the clot was formed, the suspected milk was cut into small squares of 2 cm square with a 2 cm stainless steel wire cutter. Lightly squeezed under cooling conditions to achieve a water content of the product of 75% to 80%; can also be used in the traditional "blanching" manufacturing method, that is, the suspected milk is cut and then heated a second time, the heating temperature is 47 ° C. Gently stir while heating to promote whey discharge and prevent particles from sticking to each other. At the end of the process, the curd granules continue to shrink and dehydrate, and when the granules harden, the whey is discharged. The cottage cheese produced by this method has a similar structure to that of cottage cheese.
Packed at a lower temperature of about 15 ° C, the curd granules are filtered out of water and then uniformly stirred with the prepared salt and seasonings, placed in a cheese mold or a plastic box, and stored in a cold storage as a finished product.
