Boil fresh milk by pasteurization. Does not destroy the nutrients in fresh milk.

Please check the disinfection principle of Pasteur yourself.

Operating steps:

The first method: heat the milk to 62~65℃ and keep it for 30 minutes. This method can kill all kinds of growth-type pathogenic bacteria in milk, and the sterilization efficiency can reach 97.3%~99.9%. After disinfection, only some thermophilic bacteria, thermotolerant bacteria and spores remain, but most of these bacteria are lactic acid bacteria, which are not only harmless to people, but also beneficial to health.

The second method is to heat the milk to 75 ~ 90℃ 15 ~ 16 seconds, which has shorter sterilization time and higher working efficiency. But the basic principle of sterilization is that it can kill pathogenic bacteria. If the temperature is too high, more nutrients will be lost.
