In fact, the main raw material of pasteurized milk is fresh milk source. Fresh milk source is processed into milk by pasteurization. The so-called pasteurization method is to heat the milk source and its processed products to 68-70 degrees Celsius, then keep this temperature for half an hour, and then immediately cool it. If cooled to 4-5 degrees Celsius, it can kill many bacteria in the milk source. Pure milk is made by high-temperature sterilization of milk source. Because it is treated at high temperature, it will inevitably lose a lot of nutrients, resulting in the taste of pure milk is not as good as pasteurized fresh milk.
The difference between pasteurized fresh milk and pure milk is that the shelf life of pasteurized fresh milk will be relatively short, and the storage time is only about one week, and it should be under the condition of refrigeration; Because pure milk is a high-temperature sterilization method, it will be preserved for a long time, and the shelf life is about one month. If the two are better, Pap milk will be better, but everyone has different tastes. You can buy any milk you like.
