The black cotton peach is very sour and not yet fully mature. If the spades don't soften, then you can mature. Black cotton peaches are with apples, bananas and other fruits.

Ripe apples will release ethylene, and one of the functions of ethylene is to make apples mature, so blackberries will also mature. Under normal circumstances, black cloth can be completely cooked within a week, and it tastes best at this time.

Extended data:

Just putting the black cloth in the cold storage will not make it sweet and ripe. The main function of fruit cold storage is to inhibit the activity of microorganisms and enzymes and prolong the storage period of special fruits.

Cold storage technology is the main way to keep fruits and vegetables fresh at low temperature. The fresh-keeping temperature range of fruits and vegetables is 0℃ ~ 65438 05℃. Fresh-keeping storage can reduce the incidence of pathogenic bacteria and the decay rate of fruits, and also slow down the respiratory and metabolic processes of fruits, thus achieving the purpose of preventing rot and prolonging storage period.

With the appearance of modern refrigeration machinery, the preservation technology can be carried out after quick freezing, which greatly improves the quality of fresh-keeping fruits and vegetables.
