What is the longest shelf life of black fungus

Dried fungus can usually be stored for 1-2 years under sealed and dark conditions, but the actual shelf life is affected by storage environment, packaging method, and processing technology. The shelf life of dried fungus is closely related to storage conditions. Unopened dried fungus should be stored in a cool and dry place. Vacuum packaged products have a shelf life of up to 2 years, while regular sealed packaging has a shelf life of about 1 year. During storage, it is necessary to avoid contact with moisture and direct sunlight, as high temperature and humidity environments can accelerate mold growth. High quality dried fungus undergoes strict dehydration treatment, resulting in extremely low internal moisture content and difficulty for microorganisms to reproduce, which is the basis for its long-term preservation. Regularly check whether the fungus is damp, clumped, discolored, or has a strange odor. If these phenomena occur, stop eating immediately. Some special processed black fungus may be labeled with a longer shelf life, but it should still be consumed as soon as possible after opening. The commercially available compressed fungus blocks are more resistant to storage than bulk fungus due to their high density and small air contact area. If stored improperly, such as damaged packaging or humid environment, the fungus may spoil within a few months. Freezing storage can extend the shelf life of dried fungus, but the taste may slightly decrease after thawing. It is recommended to divide into small portions to avoid repeated freezing and thawing.

It is recommended to pack dried fungus into a sealed jar or fresh-keeping bag, place it in a well ventilated and dark place, and regularly check its condition. After soaking, the fungus should be refrigerated and consumed within 24 hours to prevent bacterial growth. The best way to ensure the quality of Auricularia auricula is to purchase small quantities in daily life and plan the dosage reasonably. At the same time, attention should be paid to the differences in shelf life between products of different brands and processing methods. Before consumption, it is necessary to confirm that there are no abnormalities.
