Have you ever placed a banana in a refrigerator? Did it go bad?
If by going bad, you mean that banana peels turned black with a grotesque look, and then this is true. However, should you mean the banana got all mushy with an awful taste and over ripened, none of these is true? Despite the peels turning dark brown that makes the banana look “bad,” the edible part of the banana is still good to eat.
In fact, most banana selling companies highly recommend that you do this to help the bananas last longer while it is perfect ripeness stage. Once the banana ripeness to your liking, place it in a refrigerator to significantly slow down the conversion of starch into sugar to the extent that the ripening process is stopped.
Once in the refrigerator, the banana will soon begin to appear rotten. This is due to the polyphenol oxidase enzyme found in the bananas that polymerizing phenol in the banana peels into polyphenols. However, besides the unpleasing black peep that is a result of the above process, the banana is not negatively effective and remains as delicious as you would want it to be.
It is crucial that you do not place the banana in the fridge before reaching its optimum level of ripeness as you like. Keep in mind that, if you choose to refrigerate the banana before it is fully ripened, the ripening process will not continue even after returning it to the room temperature.
Once in the refrigerator, the bananas can stay there for about a week. This is significantly longer compared to a ripe banana in a room temperature, which for many people, seems like just 6 seconds. In case you do not like cold banana, just let the blackened banana sit for a while at room temperature then remove the peel and enjoy your sweet banana.
If the refrigerated banana looks unpleasing to you, there are several other ways for you to keep them fresh for longer. For example, slow down the ripening process by placing banana away from other fruits. Bananas have been found to put off a significant hormone ethylene than most other fruits. This facilitates and speeds up the ripening process. If you want to speed up the ripening process of a green banana and other fruits, simply put them in a paper bag overnight.
