The shelf life of pasteurized milk in the market is 5 days, 10 and 15 days. The common misunderstanding of this concern is that the longer the shelf life, the better the product. In fact, the shorter the shelf life of dairy products, the higher the nutritional value of products. As far as the sterilization methods of dairy products are concerned, they are basically divided into two categories according to the process: 1) pasteurized milk: the common pasteurized milk. As the name implies, it is pasteurized milk. "Pasteurization" is to kill pathogenic bacteria in milk for a long time at low temperature and keep bacteria beneficial to human body. However, because this method can not eliminate all microorganisms in milk, the product needs to be refrigerated, and the shelf life is short, usually only a few days. 2) Sterilize milk (ultra-high temperature instant sterilizer): use high temperature to kill all bacteria in milk. Because there are no microorganisms in milk, it can be stored at room temperature, and the shelf life is relatively long, generally up to more than 3 months. No matter what sterilization method is adopted, nutrients will be lost. For milk, heating mainly destroys water-soluble vitamins and protein. It was found that about 10% of B vitamins and 25% of vitamin C were lost during heating. Generally, the deeper the heating, the more these nutrients are lost. There is a kind of whey protein with high nutritional value in milk, and heating will also cause certain losses. The experiment shows that about 10% of whey protein is denatured during pasteurization, while 70% of whey protein may be denatured in milk sterilized by ultra-high temperature sterilizer. Therefore, pasteurized pasteurized milk has higher nutritional value. In terms of shelf life, the shorter the shelf life of milk, the less the loss of nutrients.
