What is the storage temperature for bananas

The suitable storage temperature for bananas is generally between 12-15 degrees Celsius. Excessive temperature can cause bananas to mature and rot too quickly, while low temperature can lead to cold damage and blackening of the skin. The preservation effect of bananas is mainly affected by factors such as temperature, humidity, ventilation conditions, maturity, and ethylene concentration. Bananas are tropical fruits that are sensitive to low temperatures. When the ambient temperature is below 12 degrees Celsius, banana epidermal cells will be damaged, with black spots or large areas turning black. This phenomenon is called cold damage. Although the flesh may not have gone bad, damage to its appearance can affect the eating experience. The temperature in the refrigerator compartment of a household refrigerator is usually 4-8 degrees Celsius, which is much lower than the suitable storage temperature for bananas. Therefore, it is not recommended to directly put unripe green bananas in the refrigerator. Temperatures exceeding 20 degrees Celsius will accelerate the ripening process of bananas. Under high temperature conditions, bananas release more ethylene gas, which rapidly converts starch into sugar, softens the flesh, and causes black spots on the skin. If you want to delay ripening, you can hang bananas in a cool and ventilated place, avoiding direct sunlight. Fully ripe bananas can be stored in the refrigerator compartment for a short period of time. Low temperature can slow down further decay, but they should be consumed as soon as possible after being taken out. When storing bananas, care should be taken to avoid squeezing and wrapping the stems with plastic wrap to reduce ethylene release. Separate bananas from other fruits, especially fruits with high ethylene release such as apples and pears. When purchasing, you can choose to eat bananas of different maturity levels in batches. Green bananas are suitable for storage, while yellow bananas are suitable for immediate consumption. If bananas are found to be overripe, they can be peeled and frozen for use in making milkshakes or baked goods.
