What is the difference between raw milk and fresh milk?

At present, there are many kinds of milk on the market. In fact, there are only two kinds of milk: fresh milk and long milk. In terms of processing technology, fresh milk is pasteurized and long-acting milk is sterilized at ultra-high temperature. The main difference between them is that pasteurization is an advanced method of fresh milk processing at present, which can not only preserve the nutrients in fresh milk, but also kill harmful bacteria in milk, making the processed milk delicious and pure; Although ultra-high temperature sterilization can also kill harmful bacteria in milk, it also destroys the nutrients in milk, which is not as good as fresh milk. From the perspective of consumption, the United States, Japan and other developed countries in Europe and Asia sell almost all fresh milk in the market. Therefore, fresh milk is also the inevitable trend of milk consumption in the future.
