The long-term storage methods of fresh chestnuts include cooling and refrigeration, ventilation storage, and jar storage.

1. Cool down and refrigerate

Fresh chestnuts can be cleaned and placed outside to dry the moisture on the surface, then put into a fresh-keeping bag or plastic wrap, and put the bag Seal the mouth or box mouth, and then place it in the cold storage layer of the refrigerator. This method can preserve fresh chestnuts for about a month without deterioration.

2. Ventilated storage

Due to its growth habits, fresh chestnuts will not deteriorate easily if placed in a relatively ventilated environment. When storing, we can first place the fresh chestnuts in a relatively ventilated environment to dry. After two days, find a relatively transparent and breathable cloth bag, put the chestnuts into the bag, and then place the bag in a cooler place to achieve storage. The storage time can reach about four to five months.

3. Storage in jars

After washing and drying the fresh chestnuts, put them into jars that are already relatively clean and dry, and then fill them until they are about 70-80% full. Stuff some straw inside, and then place the jar upside down on a relatively dry ground. This method can only be used to store a small amount of chestnuts, and is not suitable for large quantities.

Tips for selecting chestnuts

1. Look at the color: Chestnuts with a dark brown surface and a slight red head are generally good chestnuts. If the shell is discolored, dull or has a dark shadow, It indicates that the fruit has been eaten by insects or deteriorated by heat. Bite open a chestnut and check the color inside to see if it is the natural yellow color. If the color is different near the shell, it means it has been soaked in medicine and the medicine has penetrated into the inside of the fruit.

2. Look at the fluff: Everyone knows that the tail of chestnuts has a lot of fluff, which has a shiny surface. The hair on old chestnuts is generally less, only a little bit at the tip of the tail. New chestnuts generally have more fluff on their tails.

3. Check for insect holes: If there are no insect holes on the surface and you are still worried, you can rub the chestnut skin with your hands. If there are still no insect holes on the surface, it probably means there are no insect holes.
