Fresh milk and pure milk are two different kinds of milk products. Their differences lie in the processing methods and ingredients.
Fresh milk is raw milk directly extracted from cows. Its ingredients include protein, fat, lactose, vitamins and minerals. Fresh milk has a strong taste and delicious taste, but it is easy to be contaminated by bacteria because it has not been sterilized, so it needs to be drunk in a short time or stored in a low-temperature environment.
Pure milk is pasteurized at high temperature, which can effectively kill bacteria and viruses and ensure the safety of milk. The composition of pure milk is similar to that of fresh milk, but its fat content and nutritional composition can be adjusted through processing, for example, some fat can be removed to make skim milk, and vitamin D can be added to make fortified milk.
In general, the difference between fresh milk and pure milk lies in the handling method and safety. Fresh milk tastes good, but needs to be drunk in a short time or stored in a low temperature environment; Pure milk is sterilized at high temperature to ensure the safety of milk, but the taste may be slightly inferior to fresh milk.
