The maximum drink is 1000ml, and the minimum is 500ml, and milk is known as "the closest food to perfection", and it is also known as "white blood". In recent years, with the improvement of people's living standards, Chinese consumers' awareness of drinking milk for fitness and calcium supplementation has gradually increased. Especially for women, drinking more milk can also play a role in moisturizing the skin.

Experts unanimously said: "Fresh milk should be the first choice for choosing milk".

As we all know, fresh milk is a liquid food with the most complete nutrients and the highest nutritional value after human breast milk. Fresh milk is rich in protein, fat, amino acids, sugars, salts, calcium, phosphorus, iron and other macro, trace vitamins, enzymes and antibodies, etc., which are most easily digested and absorbed by the human body.

One is fresh milk (short shelf life) and the other is room temperature milk (long shelf life). According to its processing technology, fresh milk is pasteurized, and room temperature milk is sterilized by ultra-high temperature. The main difference between the two is that pasteurization is a relatively advanced method of fresh milk processing, which can not only preserve the nutrients in fresh milk, but also kill the harmful bacteria in the milk, so that the processed milk is delicious and pure; UHT treated milk has a long shelf life, but this process kills all microorganisms, killing the harmful bacteria in the milk at the same time, to some extent, it also destroys the nutrients in the milk, and its nutrients are not as good as fresh milk.
