(1) It should be noted that moldy tremella is poisonous and forbidden to eat.
(2) After soaking the dried tremella in water, take it out and wash it with water, that is, the tremella after water. If this swollen tremella is not used up at one time, it should not be frozen in the refrigerator when it needs to be placed. However, it can be soaked in cold water, then stored in a refrigerated room, or placed in a cool place, paying attention to changing water frequently. You can also filter out the water and let it air dry before placing it. Be careful not to freeze, otherwise it will destroy the tremella when thawing, making it broken and shapeless, and will also cause a lot of loss of nutrients in it.
(3) It is advised that people should not buy white tremella, because natural or artificially cultivated tremella is not pure white, and its normal color should be light yellow. In order to pursue white color, some processors often choose sulfide smoking, while some consumers mistakenly think that the whiter the color, the better the quality, and deliberately buy white tremella, which is actually wrong. Anyone with white color is tremella fumigated by sulfide, which is harmful to human body. Therefore, the purchase of tremella should avoid choosing white color.
