Can dried fungus still be eaten after it expires

Dried black fungus is generally not recommended for consumption after expiration, as there may be risks of mold growth or nutrient loss. The shelf life of dried fungus is affected by factors such as storage environment humidity, packaging sealing, and processing technology. After expiration, dried fungus may breed mold and produce harmful substances such as aflatoxins due to improper storage, which are difficult to distinguish with the naked eye. These toxins are heat-resistant and may damage liver function, and cannot be completely removed during the foaming process. Even if it does not mold, the protein and dietary fiber of expired dried fungus will gradually degrade, resulting in a poorer taste and reduced nutritional value. Some merchants may conceal the true shelf life by repackaging, making it difficult for consumers to determine the actual storage time.

Dry fungus that is well sealed and stored in a dry and cool environment under special circumstances may have no abnormal appearance when the expiration time is short. But if the texture is sticky, has a sour smell, or has increased black spots after soaking, it must be discarded immediately. Some people mistakenly believe that sun dried food can be stored indefinitely, but in reality, dry goods with a moisture content below 10% will still slowly deteriorate, and microbial metabolites may cause gastrointestinal discomfort.

It is recommended to choose small packaging and clearly label the production date when purchasing dried fungus, and consume it as soon as possible after opening. When storing, use sealed cans and place food desiccants to avoid direct sunlight and high temperature environments. The soaking time should be controlled within four hours. If any abnormal color or odor is found after thorough cleaning, it should be stopped from consumption. Fresh vegetables and fruits can be combined with daily diet to enhance antioxidant capacity and reduce the absorption of potential harmful substances. If you experience symptoms such as abdominal pain and diarrhea after ingesting expired dried fungus, it is necessary to seek medical examination in a timely manner.
