Because the fungus itself is dried, microorganisms can't reproduce without water. However, in the process of soaking, microorganisms have enough water, and auricularia itself is a kind of food with rich nutrition, which is easy for microorganisms to reproduce. Under the condition of high temperature, microorganisms reproduce faster.
Auricularia auricula can be soaked in cold water for 1-2 hours to reach the best soaking state of Auricularia auricula, and you don't need to extend the soaking time specially in order to pursue the taste. If you have to soak for a long time, then try to put the fungus in some cool and dry places, preferably in the refrigerator. Low temperature can effectively inhibit microbial reproduction.

Other foods that can't be eaten overnight except fungus.
1, half-boiled eggs
If the eggs are not fully cooked, the immature yolk will be eaten overnight. In case of improper storage, things will easily breed bacteria, which will be harmful to health, such as gastrointestinal discomfort and flatulence.
2. Boil water overnight
Nitrite can form carcinogenic nitrosamines in human body. Some experts have found that the nitrite content in boiled water is higher than that in raw water. Moreover, the content of nitrite increased obviously when boiling water for too long or more than 24 hours repeatedly. After standing in boiling water for 24 hours, the nitrite content is 1.3 times that of when it was just boiled.
3, tremella soup
Both the tremella fuciformis cultivated indoors and the tremella fuciformis cultivated in the wild contain more nitrates. If it is cooked for a long time, the nitrates will be reduced to nitrite under the decomposition of bacteria. Nitrite can oxidize normal hemoglobin into methemoglobin, lose the ability to carry oxygen, and cause the human body to lack normal hematopoietic function.
4. Green leafy vegetables
Because some green leafy vegetables contain more nitrates, if they are left for too long after cooking, nitrates will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating.
