Fresh milk can be heated and drunk, and drinking a glass of milk before going to bed is good for sleep. The nutritional components of fresh milk are well preserved, and most common milk in supermarkets is long-acting milk, which has been sterilized at ultra-high temperature. You can boil the milk for a while, but if you cook it for too long, the nutrition in it will be destroyed. Generally, you should drink milk, preferably warm.

Matters needing attention in heating milk

When heating milk, the time should be as short as possible and the temperature should not be too high. Generally, milk is scalded with hot water of about 80 degrees 1 min. There is no packaging. Boil in boiling water. When heating milk, many people put bagged or boxed milk into boiling water, which saves trouble. Actually, this is not right.

The temperature of boiling water is kept at about 100 degrees. At high temperature, the nutrients in milk will change, resulting in the loss of nutrients. Whether it is bagged milk or boxed milk, the packaging is not resistant to high temperature. At the continuous high temperature, milk packaging boxes or bags will decompose, and some harmful substances will be decomposed, which will affect health.
