The protein content of dried mushrooms is low after air drying, so long as the water content is low enough, it will not cause a large number of bacteria to multiply. The fat content is also low, and unpleasant smells such as spicy taste will not appear due to oxidative rancidity. However, during the storage of this kind of dry goods, vitamins and other nutrients will be slowly oxidized, so they need to be stored in sealed bags or cans.

Oxygen-free environment can delay oxidation reaction and help prevent moisture absorption and deterioration. Dried mushrooms can be stored in a cool, ventilated and dry environment, and the shelf life can reach two years without being put in a refrigerator. As long as the dried mushrooms are not mildewed and dry, they can be eaten.
