Can you still eat white wood ear fungus after it has expired?

White fungus usually refers to Tremella (Tremella fuciformis). Expired Tremella is generally not safe for consumption and may negatively affect health. The detailed analysis is as follows:

Tremella contains abundant protein, dietary fiber, fat, and various amino acids, which can supply essential nutrients to the body, enhance immunity, and reduce the invasion of bacteria and viruses. However, expired Tremella may lose most of its nutritional value and could spoil, promoting the growth of bacteria and fungi. Consuming it may cause gastrointestinal discomfort, such as bloating, abdominal pain, and diarrhea. In severe cases, it may lead to food poisoning.

It's recommended to consume Tremella as soon as possible after purchase and always check the expiration date carefully to avoid accidentally eating expired products.
