The difference between milk and fresh milk is whether it has been processed or not.

There is only one word difference between fresh milk and fresh milk, but in fact, the difference is quite big. The biggest difference is whether it has been processed or not. Fresh milk usually refers to the most primitive milk that has just been squeezed from the breast of a cow. Without any processing, there will be some bacteria in it.

generally speaking, you can't drink it directly, and you need to heat and boil it before you can drink it. Fresh milk has one more processing procedure than fresh milk, that is, sterilization. The common methods are pasteurization and ultra-high temperature sterilization, but it can't be separated from cows for more than 24 hours. If it exceeds this time, it can't be said to be qualified fresh milk in general.

storage method of milk:

1. Fresh milk should be placed in a cool place immediately after it is taken, preferably in the refrigerator.

2. Avoid exposure to sunlight or light to reduce the loss of vitamins in milk.

3. When the milk is placed in the refrigerator, pay attention to cover the bottle cap to avoid the odor.

4. After the milk is poured into other containers, it must not be returned to the original bottle until it is finished. You can put the lid back in the refrigerator, but remember to drink it as soon as possible.

5, milk should not be frozen, freezing will damage the quality of milk.
