Soaking silver fungus for a long time can easily breed bacteria and deteriorate, which may produce certain toxins and may affect the body and even cause symptoms of poisoning after consumption. Soaking the fungus for a long time may produce mimolic acid, which is a kind of biotoxin and may cause gastrointestinal reactions such as abdominal distension, abdominal pain, nausea, vomiting, etc. Patients with serious conditions may also suffer from coma and shock, which may even be life-threatening. In addition, rice fermented bacteriological acid can also cause some damage to the liver, and this toxin usually cannot be destroyed at high temperatures, so it may still have an effect on the organism after cooking. In addition, some scholars believe that long-soaked silver fungus may also produce certain nitrites, and excessive consumption may also have certain effects on the organism. Therefore, it is recommended to soak the fungus in warm water for about 2 hours and not for too long. After soaking, use water or starch to clean the silver fungus before cooking, in order to prevent the bacteria attached to the surface of the fungus from being consumed during soaking and causing infection to the organism. In addition, it is recommended to cook the soaked silver fungus at once and finish it as soon as possible. It is not recommended to consume overnight silver fungus to avoid the reduction of nitrate to nitrite in the diet, which can affect the health of the body. If you have already consumed soaked silver fungus for a long time or overnight and have symptoms such as nausea and vomiting, abdominal distension and diarrhea, it is recommended to seek medical treatment promptly.
