How many years can the fungus be stored at most

Dried fungus can usually be stored for 1-2 years in a sealed and dry environment, and the actual storage time is affected by factors such as storage conditions, packaging methods, and environmental temperature and humidity.

1. Storage Conditions

The shelf life of dried fungus is closely related to the storage environment. Ideally, it should be placed in a cool and dry place, avoiding direct sunlight and high temperature and humidity environments. Kitchen cabinets or food storage cabinets are more suitable storage locations, and it is recommended to keep the temperature below 25 degrees Celsius and the relative humidity below 60%. A humid environment can easily cause fungus to absorb moisture and mold, while high temperatures can accelerate the loss of nutrients.

2. Packaging Method

Vacuum packed dry fungus has a relatively long shelf life, up to about 2 years. It is recommended to consume regular plastic bag packaging within one year. After opening, the fungus should be transferred to a sealed container for storage, and can be paired with food desiccants to extend the storage time. Glass or metal cans are superior to plastic containers as they can better isolate air and moisture.

3. Quality Changes

Auricularia auricula stored for too long may exhibit phenomena such as darkening color, crisping texture, and weakened aroma. Dried fungus that has been aged for more than 2 years may not necessarily spoil, but its nutritional value is significantly reduced, and the content of polysaccharides and trace elements will gradually decrease. If obvious mold or odor is found, it should be discarded immediately.

4. Special circumstances

Wild fungus usually has a storage time 3-6 months shorter than artificially cultivated varieties due to its high water content and impurities. Thicker oak wood ear fungus is more resistant to storage than thin wood ear fungus. Some commercial products that have undergone special sterilization treatment may be labeled with a shelf life of 3 years, but they still need to be consumed as soon as possible after opening.

5. Eating suggestions

Long stored dried black fungus should be thoroughly soaked and carefully inspected before consumption. High quality black fungus should be semi transparent after soaking, with a flexible and elastic texture. It is recommended to seal immediately after each use to avoid repeated opening and closing of the packaging. During the hot summer season, consider storing unopened dried fungus in refrigeration.

When storing dried fungus in daily life, regular inspections should be carried out. If signs of moisture are found, they can be air dried and resealed. After soaking, the wet fungus should be refrigerated and consumed within 2-3 days. It cannot be repeatedly frozen or thawed. Reasonably control the purchase quantity, follow the first in, first out principle, and try to consume it within the optimal consumption period. People with special physical conditions should confirm that the fungus has not spoiled before consumption to avoid causing gastrointestinal discomfort.
