The data show that milk should not be drunk with ice, because after milk is frozen, the fat in milk is separated from protein, the taste is obviously weakened, and the nutrients are not easily absorbed; There is also some data that milk should not be boiled. If the temperature is too high, protein in milk will change from sol state to gel state, which will lead to precipitation and affect the quality of dairy products.

It is best to drink the milk after disinfection and sterilization fresh, and it can be drunk within the shelf life, and there is no need to heat it before drinking. If some people's stomachs are not suitable for eating cold, or like drinking hot milk, they can heat the milk properly, but the temperature should not be too high to boil, so as not to cause the loss of nutrients. It is generally recommended to heat to below 75℃.
