After the mixed auricularia auricula is evenly mixed, it needs to be put into a fresh-keeping box, then covered with plastic wrap and put into the refrigerator for refrigeration. Refrigeration can prolong the storage time of food, and it can be eaten overnight, which will not cause deterioration and mildew, nor will it affect health.

If the cold fungus is stored incorrectly, such as directly at room temperature, especially in hot weather, at room temperature, it may lead to the deterioration of cold fungus, which will breed a lot of bacteria and mold, which will affect human health after eating.
