If it is well preserved, it may last for a long time. It should be noted that tremella is usually inedible after expiration, which may affect your health, so you should pay attention to eating tremella during the shelf life.
Tremella has a high nutritional value and is generally well preserved. It may be stored in a dry and low temperature environment for a long time, about three years. However, if we do not pay attention to the storage of tremella, it may be stored in a humid environment, and the general storage time may be shortened, which may easily lead to deterioration and loss of nutritional value of tremella. When it is found that tremella has deteriorated or exceeded the normal shelf life, it needs to be thrown away in time, because enteritis may occur after eating, and symptoms such as abdominal pain and diarrhea are prone to occur.
