What are the correct methods for storing shiitake mushrooms?

1. Dry storage. Shiitake mushrooms are highly absorbent and not easy to store; when their moisture content is high, they are prone to oxidative spoilage and mold. Therefore, shiitake mushrooms must be dried before storage. An appropriate amount of lump lime or dry charcoal and other moisture-absorbing agents must be placed in the storage container to prevent moisture from returning.

2. Low-temperature storage. Shiitake mushrooms must be stored in a cool, ventilated place; if conditions permit, the container holding the shiitake mushrooms can be sealed and then placed in a refrigerator or cold storage for storage.

3. Light-proof storage. The infrared rays in light will raise the temperature of shiitake mushrooms, and ultraviolet rays will trigger photochemical reactions, thereby accelerating the spoilage of shiitake mushrooms. Therefore, shiitake mushrooms must be kept from being stored under strong light, and at the same time, packaging with light-transmitting materials should also be avoided.

4. Sealed storage. Oxidation reaction is an unavoidable process in the deterioration of shiitake mushrooms; if the oxygen supply is cut off, their oxidative spoilage can be inhibited. Sealed containers such as iron cans and ceramic jars can be used to store shiitake mushrooms, and the containers should be lined with food bags. The container opening should be opened as little as possible; when sealing, the air in the lining bag should be expelled, and if conditions permit, oxygen-extraction nitrogen-filled bags can be used for storage.

5. Separate storage. Shiitake mushrooms have extremely strong adsorption capacity and must be stored separately, that is, the container holding shiitake mushrooms must not be mixed with other items, and the warehouse storing shiitake mushrooms should not be mixed with other materials. In addition, containers that emit odors or containers that have absorbed foreign odors must not be used to store shiitake mushrooms.
