Preservation methods of bananas:

The reason why bananas turn black is mainly because when they are laid flat, the stress on the contact surface is relatively large, which causes the epidermal cell membrane to be crushed, and the oxidizing enzymes inside will flow out, thus turning black. If you don't want bananas to be oxidized and blackened in a short time, you can choose to hang them. Without the direct compression area, the cell membrane will not be destroyed and naturally it will not be oxidized easily.

In addition, most bananas have ripening agents, so after you buy them home, you can rinse them with clear water several times first, which can reduce the effect of ripening agents and prolong the storage time.

Bananas are tropical fruits. If you don't want them to turn black, you should also pay attention to the temperature when storing them. Generally, it is the most suitable between 8-23 degrees Celsius. Otherwise, if the temperature is too high, it will be overcooked and discolored, and if the temperature is too low, it will be frostbitten. When preserving bananas, you should pay special attention to it. Don't put them in the refrigerator for cold storage, otherwise the pulp will be frozen and turn dark brown, and the taste will be very bad.
