How to store bananas for a long time

You can wrap the banana with newspaper and store it in a cool, ventilated place. You can also place the banana with the concave side down, or tie the root of the banana with a rope and hang it up to reduce the pressure area. You can also wrap the rhizome of the banana tightly with plastic wrap.

The most suitable storage temperature for bananas is 8-23℃. If the temperature is too high, they will easily overripe and change color. If the temperature is too low, they will easily get frostbite.

Fully ripe bananas can also be placed in the refrigerator. Although their surface may turn black, it generally does not affect their consumption.

It is best to wrap unripe bananas in newspaper and place them in a cool place. You can also expose them to the sun to ripen them.

What are the consequences of eating raw bananas?

Eating too many raw bananas may cause or aggravate constipation. The skin of raw bananas is usually green or very yellow, and because the flesh contains more tannic acid, it tastes hard and astringent. Tannic acid has an inhibitory effect on the digestive tract, inhibiting gastrointestinal fluid secretion and peristalsis. Therefore, abdominal pain or constipation may occur.

Not only do raw bananas and ripe bananas taste different, but they also have very different effects. Raw bananas contain a lot of tannic acid, which causes a bitter taste, and tannic acid can make stools dry and hard, causing constipation.

But ripe bananas are just the opposite. They are rich in dietary fiber and vitamins, which can speed up gastrointestinal motility and moisturize the intestines and promote bowel movements.
