Food should not be mixed together. In order to maintain hygiene, it is best to pack the food home according to the types and use clean and sealed containers to avoid cross-contamination and secondary pollution.

2. Pack the food and cool it before putting it in the refrigerator.

After the hot food suddenly enters the low temperature environment, the food center is prone to qualitative change. The hot air brought by the food will cause the condensation of water vapor, promote the growth of mold, and lead to food mildew.

Packaged food should not be stored for a long time.

Generally speaking, heating at 100℃ can kill some bacteria, viruses and parasites in a few minutes. However, if food is stored for too long, the bacteria in food will release chemical toxins, and there is nothing you can do to heat these toxins.

4. The packaged food must be heated before eating!

Because the temperature in the refrigerator can only inhibit the reproduction of bacteria, but can not completely kill bacteria. If it is not thoroughly heated before eating, it will easily cause intestinal diseases after eating. If it is not heated before eating, it will cause discomfort after eating, such as dysentery or diarrhea.
