Fresh auricularia auricula can be stored in the refrigerator for 3 ~ 7 days, because the temperature of the freezer is usually between 3 ~ 10℃. At this temperature, although all kinds of fungi and bacteria can still survive, their activity ability is greatly reduced, and their reproduction speed will become slow, which will not affect the fresh fungus in a short time, so the fresh fungus can still be stored in the refrigerator for a long time.

There is a protective film on the surface of the eggshell to prevent bacteria from entering the egg. If you wash eggs, it will destroy the film, make it easier for bacteria to enter and accelerate the deterioration of eggs.

Precautions for food preservation in refrigerator

Some foods will rot faster in the refrigerator, such as immature tropical fruits. Tropical fruits are usually picked when they are immature and then ripened by their own ethylene, but low temperature will inhibit the release of ethylene. Therefore, if they are not mature, they will mature more slowly and may be frostbitten and rotted.

Vegetables and fruits should be stored separately. Vegetables can stay in the refrigerator for a short time and usually start to go bad after a few days, and many fruits can release ethylene, such as apples, bananas, mangoes and avocados. Although the low temperature environment can inhibit the release of some ethylene, it is too difficult to keep vegetables fresh for a long time, so these ethylene will still accelerate the decay of vegetables.
