1. Raw chestnuts can be stored in the cold storage layer of the refrigerator if they want to be preserved for a short time. The method is: put it in a fresh-keeping bag, tie the mouth tightly and put it in a cold storage layer. However, in the process of cold storage, the water inside chestnut is constantly evaporating, and there will be water on the inner wall of bag and the surface of chestnut. If the water is not drained for a long time, it will also lead to chestnut rot. So, take the chestnut bag out of the refrigerator every two or three days.

2. Storage method of cooked chestnuts. Another method is refrigeration in the refrigerator. Wash chestnuts, put them in a pot, add water to boil for three minutes, turn off the fire, then take them out, peel them, put them in a bag, vacuum them, and put them in the refrigerator for one to two months. If you don't have a vacuum cleaner, you can put chestnuts in a fresh-keeping bag, empty the gas as much as possible, tie the bag tightly and put it in the frozen layer of the refrigerator. However, frozen chestnuts should not be thawed before eating, but directly heated, otherwise it will affect the taste.

3. Whether it is stored in the cold storage layer or the frozen layer of the refrigerator, it should be eaten as soon as possible to avoid placing it for too long.
