Dry storage: Mushrooms have strong water absorption. When the water content is high, they are prone to oxidation and deterioration, and may also become moldy. Therefore, shiitake mushrooms must be dried before storage. An appropriate amount of hygroscopic agents such as lump lime or dry charcoal must be placed in the storage container to prevent moisture return.

Low-temperature storage: Mushrooms must be stored in a low-temperature and ventilated place. If possible, the container containing the mushrooms can be sealed and stored in a refrigerator or cold storage.

Store away from light: The infrared rays in the light will heat up the mushrooms, and the ultraviolet rays will trigger photochemical reactions, thus accelerating the deterioration of the mushrooms. Therefore, it is necessary to avoid storing mushrooms under strong light and avoid packaging them with light-transmitting materials.

Sealed storage: Oxidation reaction is a necessary process for the qualitative change of mushrooms. If the oxygen supply is cut off, its oxidative deterioration can be inhibited. Mushrooms can be stored in sealable containers such as tin cans and ceramic jars, and the containers should be lined with food bags. The container opening should be opened as little as possible, and the air in the lining bag should be discharged when sealing. If possible, it can be stored in oxygen-exhausted and nitrogen-filled bags.
