1. Cooling and cold storage: The common method for preserving fresh chestnuts is cold storage. Fresh chestnuts can be cleaned, placed outside to dry the moisture on the surface, put in fresh-keeping bags or plastic wrap, sealed at the bag mouth or box mouth, and placed in the cold storage layer of the refrigerator. This method can preserve fresh chestnuts for about one month without deterioration.

2. Ventilation preservation: Because of its growth habit, fresh chestnut is not easy to deteriorate when placed in a ventilated environment. When preserving, we can first put fresh chestnuts in a relatively ventilated environment for drying. After two days, find a more transparent and breathable cloth bag, put the chestnuts in the bag, and then put the cloth bag in a cool place to achieve the function of storage.

3. jar preservation: fresh chestnuts can also be preserved in jars or clay pots. First, clean and dry the fresh chestnuts, then put them into a relatively clean and dry jar, and then put some straw into it when it is about seven or eight minutes full, and then put the jar upside down on a relatively dry ground. This method can only be used to store a small amount of chestnuts, not a large amount.

4. Sand-gravel mixing: dry fresh chestnuts, put them in a jar-shaped container, and then pour a proper amount of dry yellow sand into it, and the ratio of yellow sand to chestnuts is about 3: 1. Sprinkle a little water on the surface of the yellow sand, so as to prevent the water in the fresh chestnut from completely evaporating. This can also better achieve the function of storing chestnuts.

5. Spread and air storage: The fresh method can also be directly stored in a cool, dry and ventilated place. First of all, fresh chestnuts can be stored for two months only by completely spreading them out and placing them in a ventilated place, which needs to be dry and ventilated all the year round and is out of direct sunlight.
