How to choose good auricularia auricula;
First, look:
Normal fungus: pure black on the front and brown on the back. In addition, the moisture content of high-quality black fungus is very low, which makes it feel light in your hand and brittle when pinched by your hand.
Abnormal auricularia auricula: the front is black and impure, and there are many white attachments on it.
Second, the bubble:
Normal fungus: it is easy to soak hair, and small ones can soak big ones.
Abnormal auricularia auricula: The swelling degree after soaking is extremely limited. Some unscrupulous traders "process" black fungus with pigment and soak it in clear water, and soon the water turns black.
Third, the smell:
Fresh auricularia auricula: no acid, odor and other odors. If it is stored for a long time, it will produce sour gas or other peculiar smell due to protein and fatty degeneration.
Auricularia auricula has a problem: if it smells musty, it means it has been spoiled by damp.
Fourth, taste:
Pure auricularia auricula: no odor when licked lightly.
Problem auricularia auricula: lick the back of auricularia auricula when you buy it. If there is astringent, alkaline, sweet or pungent taste, it means that the quality is poor after additional "processing".
