And the spoiled chestnuts can no longer be eaten.

Cooked chestnuts can also be put in the refrigerator. The low temperature environment of refrigerator can inhibit the growth of bacteria, thus delaying the deterioration of chestnut and prolonging the shelf life. They can also be kept in the refrigerator for a longer time.
