Can fresh milk be frozen

Can fresh milk be frozen? This question needs to be studied carefully, because almost every household drinks fresh milk, so the way we preserve fresh milk is of course to use the freezing method. Then, will the nutrition of fresh milk disappear after freezing, or will there be any bad effects after freezing fresh milk? Fresh milk tastes better after freezing, but can fresh milk be frozen?

Can fresh milk be frozen? Before answering this question, we must first understand what fresh milk is. Fresh milk is fresh milk. Fresh milk is rich in protein and a variety of trace elements needed by our human body. Drinking fresh milk regularly can supplement the body's nutrition.

Milk, one of the oldest natural beverages, is known as "white blood" and its importance to the human body can be imagined. As the name suggests, it is milk squeezed out from female cows. In different countries, milk is divided into different grades. Currently, the most common ones are whole fat milk, low fat milk and skim milk. There are quite a lot of additives in milk on the market, such as high-calcium low-fat milk, which emphasizes the addition of calcium.

The inorganic salts in milk are also called minerals. Milk contains cations such as Ca2+, Mg2+, K+, Fe3+ and anions such as PO43-, SO42-, Cl-; in addition, there are trace elements I, Cu, Zn, Mn, etc. Calcium in nature exists in a chemical state. Only after it is passively absorbed by plants to form biologically active calcium can it be better absorbed and utilized by the human body. Milk is rich in active calcium and is one of the best sources of calcium for humans. One liter of fresh milk contains about 1,250 mg of active calcium, which ranks first among many foods. It is about 101 times that of rice, 75 times that of lean beef, and 110 times that of lean pork. Not only is it high in content, but the lactose in it [2] can also promote the absorption of calcium by the human intestinal wall. The absorption rate is as high as 98%, thereby regulating the metabolism of calcium in the body, maintaining serum calcium concentration, and promoting bone calcification. Good absorption is especially important for calcium supplementation. Therefore, the statement that “milk can supplement calcium” has scientific basis.

For middle-aged and elderly people, milk has another big benefit, that is, compared with many animal proteins with high cholesterol, the cholesterol content in milk is lower (milk: 13 mg/100 g; lean meat: 77 mg/100 g). It is worth mentioning that certain ingredients in milk can inhibit the amount of cholesterol produced by the liver, so that milk can also have the effect of lowering cholesterol.

Above we introduced what fresh milk is. We know that fresh milk is fresh milk. Our daily way of preserving fresh milk is to freeze it. However, freezing fresh milk is not scientific because freezing fresh milk can easily change the properties of the protein in it and cause the fat to stratify, making it difficult for the human body to absorb.
