Once the shelf life of pure milk has passed, the ingredients in it may change, which may lead to adverse consequences such as acute gastroenteritis and food poisoning after drinking. Pay attention to maintaining good living habits and avoid eating expired drugs or food.

The quality of pure milk is generally good during the shelf life. After the shelf life, the antiseptic function usually disappears, and the nutrients in milk will gradually disappear. Even in winter, it is impossible to completely inhibit the growth of bacteria and mold.

After drinking spoiled pure milk, the nutrients in it cannot be absorbed, and bacteria and molds may enter the gastrointestinal tract, which may easily induce acute gastroenteritis, cause nausea and vomiting, and may also lead to discomfort such as dizziness, headache and diarrhea, which may cause serious harm to health.

Preservation method of pure milk

1. Fresh milk should be put in a cool place immediately, preferably in the refrigerator.

2. Don't expose the milk to sunlight or direct light. Sunlight and light will destroy several vitamins in milk and make it lose its flavor.

3. Pour milk into cups, teapots and other containers. If you haven't finished eating, cover it and put it back in the refrigerator. Never pour it back into the original bottle.

The milk should be put in the refrigerator, and the bottle cap should be covered to prevent other odors from entering the milk.

5. Too cold also has a bad effect on milk. If milk freezes into ice, its quality will be damaged. So don't freeze the milk, just put it in the refrigerator.

6. After the milk is retrieved, if you don't drink it immediately, you can put it in the refrigerator. Before storage, clean and dry the bag to prevent surface dust from polluting other foods, and don't open your mouth to prevent milk from absorbing odor.

7. The best temperature for milk preservation is 2-8 degrees.
