The fungus is tested to see if it produces aflatoxin after soaking for a long time.

Biotoxins such as penicillins as well as nitrites.

By testing the content of biotoxins and nitrites in the fungus, it is judged whether it can still be eaten.

Shelf life of dried fungus:

Dried fungus has a shelf life and can generally be stored for about two years. The content of fat and protein in fungus is relatively low, and it is not easy to cause the reproduction of bacteria after drying, and it will not produce peculiar smell due to oil oxidation. When storing fungus, it is necessary to put it in an airtight jar or sealed bag, and the isolation of oxygen can delay oxidation and prevent moisture, thereby prolonging the storage time.

Dried fungus does not need to be refrigerated or frozen, and is generally placed in a cool, dry place.
