Old tremella stored for a long time will not only turn yellow in color, but also have sour gas or other unpleasant smells due to the denaturation of protein and fat components.

taste

Some people, when buying tremella, think that the whiter the color, the better the quality, but they are often cheated. Because tremella can be smoked with sulfur to yellow, making people look white; However, after a long storage time, 10 ~ 20 days, it will be oxidized and reduced to the original yellow due to contact with air. Tremella itself should be tasteless, so try it when you buy it. If there is a pungent or pungent feeling on the tongue, it can be proved that the tremella is smoked with sulfur and is fake.
