The nutritional value of general milk will not decrease, and it is not recommended to continue drinking pure milk if it is not properly preserved. Pro-milk refers to milk close to the shelf life. If properly preserved, it will generally not deteriorate. The nutritional value is the same as that of fresh pure milk, and it can be drunk continuously. Under good preservation conditions, there is no difference in nutritional value between the temporary milk and fresh milk, and the temporary milk still contains nutrients such as protein and fat.

Protein and other nutrients in milk will usually precipitate and deteriorate if the milk is improperly preserved and placed in a high-heat environment for a long time, so it is not recommended to continue drinking at this time. It is recommended to buy milk with a new date as far as possible, and some milk has a short shelf life. Check the date carefully when buying to avoid buying expired food.

Precautions for purchasing and storing temporary food:

1. Frozen prepackaged foods, such as ice cream, quick-frozen dumplings, quick-frozen dumplings, etc. It requires high storage conditions, most of which are at-65438 08℃. Pay attention to the preservation conditions to avoid deterioration after purchase.

2. Foods with less water content such as lotus root starch, oatmeal and melon seeds generally have a long shelf life and are not easily contaminated by microorganisms. However, the consumption cycle of this kind of food is relatively long, so it is necessary to pay attention to sealing it after opening and eating it as soon as possible.

3. Microorganisms are not easy to survive in foods with high sugar content, so foods such as honey, candy and preserves have long shelf life and are not easy to be contaminated by microorganisms. However, if it gets wet, it will not only affect the taste, but also shorten the shelf life, so it should be stored in a closed and low-temperature environment.
