Fresh milk is more nutritious.

The difference between fresh milk and pure milk is: different sterilization temperatures, different shelf life, and different nutritional losses.

1. The sterilization temperatures are different. Fresh milk is also called pasteurized milk. It adopts continuous mild heating pasteurization method. The sterilization temperature is relatively low, usually 63 to 85 degrees Celsius. It can kill all pathogenic bacteria and ensure the safety of milk. Pure milk is sterilized by instant high temperature, reaching a temperature of 135 to 150 degrees Celsius, which can kill all microorganisms in the milk.

2. The shelf life is different. Fresh milk is always inseparable from the refrigerated storage environment of 0 to 10 degrees Celsius, that is, it must be stored in the refrigerator. The shelf life is short, only 2 to 7 days; pure milk has a longer shelf life, up to 2 to 12 days at room temperature. months.

3. Nutritional losses are different. Due to the low sterilization temperature of fresh milk, the nutrients of the milk can be relatively intact; while the nutrients in pure milk are lost more. Extended information

Drinking milk is mainly to obtain high-quality protein and nutrients such as calcium, phosphorus, and vitamin D from milk. Among them, protein is one of the important criteria to consider whether milk is of high quality. According to national standards, the protein content of milk should be no less than 2.8%. The protein content requirement of milk drinks is not less than 1.0%.

Therefore, milk and milk drinks can be distinguished from protein. It can also be seen from the ingredient list that the first ingredient list of milk drinks is "water and white sugar", while for real milk, the first ingredient should be "milk".
