If it is an unopened donkey-hide gelatin block, it should be tied tightly in an edible packaging bag and stored in the refrigerator. If the crushed donkey-hide gelatin pieces or collagen powder are opened, they should be bottled and sealed in the refrigerator, and nourishing foods such as home-cooked glue paste should also be sealed and stored in the refrigerator. If the donkey-hide gelatin stored at home becomes soft due to deliquescence and becomes moldy, it can no longer be eaten.
Eating deteriorated Ejiao will cause diarrhea and vomiting, which will affect your health. In addition, in winter, I am most afraid of being broken by wind, so I should pay attention to sealing. There is a folk saying that "the older Ejiao is, the better", but if Ejiao is not properly preserved, it is easy to mold and melt. Ejiao can be stored in a wooden box or a sealed box, and a little ash or other moisture absorbent can be put on the bottom layer to prevent Ejiao from swelling due to moisture.
