For milk stored in the refrigerator for a long time, supercooling is easy to cause gastrointestinal discomfort, so it can be heated properly. However, it should be noted that the longer the heating time and the higher the temperature, the vitamins and lactose contained in milk will be destroyed, thus reducing the nutritional value of milk. Generally speaking, milk can be directly heated by microwave oven, boiling pot, etc. Or it can be heated by water.
