The weather is slowly starting to get hot, and we all stuff the fruit into the refrigerator when we buy it, and we all know that the refrigerator can keep the fruit fresh and chilled. But wait, not all fruits can be kept fresh in the refrigerator! Bananas are shivering, refusing to join the fridge army! 
What happens when you put a banana in the fridge?
It's not bad, it's not poisonous, but it's just not delicious. When a ripe banana is put in the refrigerator, the skin will turn black, and the flesh will become softer, which will be even more difficult to put away. If you put an unripe banana in the refrigerator and the back-ripening process of the banana is interrupted, you may have eaten it before it is ripe.
Why do bananas in the fridge look like this?
Banana is a tropical fruit, and temperature is an important factor in the storage and preservation of bananas.12 20 It is more conducive to the preservation of bananas. The temperature of the refrigerator layer is generally 0 -12, which is just outside the comfort zone of the banana temperature, and too low a temperature will cause frostbite to the banana.
When the storage temperature is lower than 10, the peel of the banana will first be unbearable, the cells will be destroyed by low temperature, and the polyphenols in it will begin to oxidize and turn black. The skin of the banana is not well protected, and although the meat inside is not broken, it quickly loses its protection.
Unripe bananas may reach re-ripening in a day or two at room temperature, and when they are placed in the refrigerator, they will feel that they are not yet ripe and stop producing ethylene.
Bananas are ripened by ethylene, and without the ripening agent, the bananas are frostbitten, which is too good for freshness, and the banana is not ripe when you are almost finished. Bananas taste hard, astringent and not sweet, and unripe bananas are easy to constipate if you eat too much.
This is the case with many tropical fruits similar to bananas, such as mangoes, pineapples, avocados, and papayas, which need to be ripened and are not suitable for keeping them fresh in the refrigerator.

To make it easier to transport, bananas are picked before they are fully ripe and then sprayed with a ripening agent that produces ethylene. Rinse the bananas and dry them or dry them, as less ripening agent will slow down the ripening of the bananas and prolong the storage time.
Wrap the bananas
Bananas themselves release ethylene to ripen them, and wrapping the base of the banana in tin foil or plastic wrap will prolong the preservation time of the banana.
Wrapping the banana whole with plastic wrap or plastic bag can prevent the banana from releasing ethylene and prolong the freshness time.
Flip or hang the banana upside down
Both methods will protect the fragile bananas from crushing them.
Hanging bananas do not squeeze each other, the peel and flesh are well protected and will last for a long time if they are not broken.
