What is the composition of milk?
Milk is one of the favorite foods in people's daily life. Its main components are water, fat, phospholipids, protein, lactose, inorganic salts and so on. It is rich in nutrients and minerals.

Among more than 20 kinds of amino acids, there are 8 kinds of amino acids necessary for human body. Milk protein is completely protein, and the digestibility is as high as 98%. Milk fat is the best quality fat. Its digestibility is above 95%, and it contains a lot of fat-soluble vitamins. Lactose in milk is galactose and lactose, which are the most easily digested and absorbed sugars.

Minerals and trace elements in milk are dissolved, and the contents of various minerals, especially calcium and phosphorus, are appropriate and easy to digest and absorb.

Introduction:

1. Milk should not be directly exposed to the sun.

Vitamin B, vitamin C and other substances in milk will soon disappear after being exposed to the sun. Even if it is only exposed to very weak sunlight, the content of vitamin B will be reduced by at least half after more than 6 hours. In addition, containers for storing milk should not be transparent and kept in a cool and dark place.

Second, milk can't be frozen.

Milk can be stored indoors at room temperature or in the refrigerator, but not in the frozen layer of the refrigerator. Because after the milk is frozen, substances such as fat and protein will be separated, casein will coagulate in granular form, the taste will become weak, and the nutrients will not be easily absorbed by the human body.
