This method is the most common way to preserve raw chestnuts at home. The principle is to inactivate the bacteria on the surface of chestnuts through the sterilization of salt water, and then dry the water to avoid the living conditions of bacteria. Finally, the bacteria in the air can be isolated by vacuum sealing. Three-step isolation can effectively preserve raw chestnuts for a long time. This method can keep raw chestnuts for about 2 months at the longest.
2. Ventilation preservation method: wash fresh chestnuts with concentrated brine for 3 minutes, dry the water with a towel, put them in a sieve basin, and put them in a ventilated place to dry the water naturally; Then put it into a dry net bag or a clean sack and store it in a ventilated place.
This method is suitable for the preservation of a small amount of chestnuts. The principle is to sterilize and inactivate chestnuts with salt, then reduce the bacteria-producing ability by air drying, and finally store them in a dry and dry ventilated place. Because it is still possible to contact with air moisture, this method can only store chestnuts 1 month at most.
3. Pot preservation method: soak fresh chestnuts in light salt water 10 minute for sterilization, and at the same time clean the pot, dry it in the sun or put it in a ventilated place;
Then take a clean anhydrous sack, put all the chestnuts in it and tie them tightly; Put it in a crock, cover it with stones or heavy objects, and keep it like this.
