Can I eat the pre packaged fungus that has been refrigerated for a few days

Once the fungus has been refrigerated, it can generally be consumed if it has not spoiled, but it is not recommended to continue consuming it if it has been stored for more than 3 days. Improper storage of fungus may breed bacteria or produce toxins, with main risks including microbial contamination, sensory changes, and loss of nutrients.

Auricularia auricula has a shorter storage time in a refrigerated environment, and it is usually recommended to consume it within 2 days. refrigeration temperature can delay microbial growth, but cannot completely inhibit it. After foaming, the fungus has a high water content and a soft texture, making it easier to become a bacterial culture medium. If the seal is well sealed during refrigeration and there are no signs of deterioration such as mucus, odor, or dark color, it can still be consumed after brief storage and thorough heating. In some cases, refrigerated fungus may spoil prematurely. When the summer temperature is high or the refrigerator temperature is unstable, the bacterial growth rate accelerates. Repeated thawing and refrigeration can damage the cell structure of Auricularia auricula and accelerate decay. If the surface of the fungus is found to be sticky, emitting a sour and rotten smell, or has a soft and rotten texture, it indicates the growth of toxins such as rice fermentation bacteria acid and must be discarded. After refrigeration, the taste of black fungus will gradually deteriorate, its nutritional value will decrease, and the risk of cold mixing is higher.

It is recommended to soak the fungus as needed each time and avoid prolonged refrigeration. Before consumption, observe for mold or odor, thoroughly clean and cook at high temperature for more than 10 minutes to kill bacteria. People with weak gastrointestinal function, pregnant women, and children should pay special attention to freshness and seek medical attention immediately if they experience abdominal pain and diarrhea. Dry fungus can be stored in a cool and dry place in daily life, and cooked as soon as possible after soaking to preserve the best flavor and nutrition.
