Can leftover black fungus be eaten overnight

Whether leftover black fungus can be eaten overnight depends on storage conditions. If refrigerated and not spoiled, it is usually edible; If stored at room temperature or if there is an odor or sticky feeling, it is not recommended to consume. Auricularia auricula contains abundant protein and polysaccharides, which can easily breed bacteria under improper storage conditions. Microorganisms reproduce slowly in a refrigerated environment, and overnight storage of black fungus in a sealed container can generally maintain safety. Before consumption, it is necessary to observe whether the color has darkened, the texture has softened, or if there is a sour taste. Heating thoroughly to boiling can further reduce the risk. Ear fungus stored at room temperature is prone to decay and deterioration, especially in high temperature environments during summer. Even if there is no significant change in appearance, harmful substances may still be produced due to microbial metabolism. Some people have weak gastrointestinal function and may experience discomfort symptoms such as abdominal pain and diarrhea after consumption. After soaking, more attention should be paid to the fungus, as high moisture content can accelerate the deterioration process.

It is recommended that after cooking the fungus, it should be consumed as a meal. If it needs to be stored, it should be refrigerated as soon as possible for no more than 24 hours. Thoroughly heat before consuming again, avoiding cold dishes or simple reheating. Pay attention to the condition of food in daily life and discard it immediately if any abnormalities occur. Reasonably planning the amount of ingredients and reducing the production of leftovers is the best way to ensure food safety.
