Banana is a typical jumping fruit. Bananas picked from trees are green, hard and astringent. After a period of storage and post-ripening, the chlorophyll in the fruiting body is converted into carotene, and the peel turns from green to yellow. The starch contained in bananas is converted into sugar, and the astringency is converted into sweetness before it can be sold and eaten.
Pick bananas when they are ripe, because they ripen quickly. If they are picked when they are ripe, they taste bad and look stale. Then, after bananas are picked, the storage temperature is also high, generally 1 1- 13 degrees Celsius, while the fruits and vegetables stored in the refrigerator are generally around 4 degrees Celsius, up to 8 degrees Celsius. Bananas are easy to freeze if they are placed in this environment. If they are placed for one day, they will turn black, become soft and rot, and their taste will become worse, even appear patches or rot.
