Heating milk does reduce the nutritional value of milk. Many nutrients in milk, such as vitamins, protein and bioactive substances, are sensitive to high temperature and are easily destroyed during heating.
The higher the heating temperature, the longer the heating time and the more serious the damage. In particular, some friends will pour milk into a pot and boil it directly, or put it in a microwave oven to heat it at high temperature, which will greatly reduce the nutritional value of milk. Experiments show that once the milk is heated above 60℃, the nutrients begin to be destroyed.
When heated above 100℃, many protein components will undergo denaturation reaction, and a large number of vitamins will be lost. In particular, the bioactive components, which can be called milk essence, are easily destroyed after intense heating. Sacrificing nutrition for taste, drinking "dead milk" without bioactive substances is not worth the candle.
