Soaked and steamed black fungus is freezable in the refrigerator.
Soaked fungus can generally be frozen. However, you need to observe whether the fungus has deteriorated or not, because soaked fungus is stored in the refrigerator without being strictly sterilized, which itself will carry some microorganisms, such as bacteria, and is more prone to deterioration.
Before consumption, it should be thawed in advance, and then look for the presence of rotting and deteriorating phenomena such as crumbly texture, foul smell, bacteria, etc. If you accidentally eat this kind of fungus, toxic reactions may occur, such as nausea, vomiting, abdominal distension, abdominal pain, diarrhea and so on.
For black fungus, it is recommended to cook immediately after soaking, fresh state consumption can ensure its good nutritional status.
