Bananas cannot be kept fresh in the refrigerator. Banana is a typical tropical fruit that grows in a tropical environment. One of the most significant characteristics of tropical fruits is that they are afraid of cold damage. If the ambient temperature is too low, it will not only be detrimental to their growth, but also accelerate their aging. On the contrary, it breaks easily. Therefore, bananas cannot be stored in the refrigerator. If you put it in the refrigerator, not only will it not go bad as we think, but it will probably cause frostbite to the banana. Characteristics of bananas: Rinse off the ripening agent on the surface of the banana with water, and then dry it with clean paper or towel, which can keep the banana longer; there is also a hanging method, which simulates the banana still growing on the tree. Like, hanging bananas can reduce the pressure area and prevent bananas from deteriorating easily. Bananas are subtropical fruits and have poor adaptability to low temperatures. If put in the refrigerator, it is easy to get "frostbite", black spots will appear on the surface, the texture will become soft and rotten, and plaques will appear, which will affect the taste. The temperature for banana storage is generally 11-13 degrees Celsius, while the temperature for refrigeration is generally 4-8 degrees Celsius. Therefore, it should be placed indoors in a cool, dry, and ventilated place when the weather is hot. Bananas are rich in protein, fat, carbohydrates, dietary fiber, carotene, B vitamins, vitamin C, niacin, calcium, phosphorus, iron, etc. Bananas contain a lot of carbohydrates.
