Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese and molybdenum. The most rare thing is that milk is the best source of calcium for human body, and the ratio of calcium to phosphorus is very suitable, which is beneficial to the absorption of calcium. There are at least 100 complex species, and the main components are water, fat, phospholipids, protein, lactose and inorganic salts.
Milk is people's favorite nutritious food. However, milk contains more fat, and the fat content per100g of milk is more than 4g. This fat content is not good for those who are obese and have high blood fat. In the absence of skim milk, you can skim it yourself to make skim milk. After the fresh milk is boiled with low fire, keep it away from the fire source and let it cool. After forming a film (cream) on the surface of milk, peel it off gently. Then the milk is boiled, cooled, and the film is removed, and this is repeated several times until there is no conjunctiva on the surface of the milk after cooling. In this way, the fat is removed and it becomes skim milk.
