Tips to keep bananas longer

Bananas are a fruit that many of us love to eat. Bananas are soft, sweet, and fragrant, but if we buy too many, they will go bad easily if we can't eat them all at once. So how can we extend the shelf life of bananas?

How to prolong the shelf life of bananas

Normally, after people buy bananas, they will pile them on the table or in a fruit bowl. As a result, within a day, you will find that the surface of the bananas that touches the table or fruit bowl begins to turn black. This is due to chemical changes inside the banana.

The banana's epidermal cells contain an oxidase. Normally, it is tightly wrapped by the cell membrane and does not come into contact with the air. However, once it is damaged or frozen, the cell membrane ruptures and the oxidase flows out, reacting with oxygen in the air to produce a black compound, which is the "ugly" black spot.

The best storage time for bananas

When the banana is placed flat, the entire weight is on the contact surface, and the pressure there increases, which may break some of the cell membranes of the epidermal cells on the contact surface, causing the oxidative enzymes inside to flow out, causing oxidation reactions and producing black spots. It is best to hang the bananas you buy to reduce the pressure area, so that the bananas can stay "beautiful" for longer.

In addition, if you rinse the bananas several times with clean water immediately after buying them, you can reduce the corrosion of the ripening agent. Under the same external conditions, the rinsed bananas can be stored for 5 to 7 days longer without deterioration.

Bananas are best stored at 8-23 degrees Celsius. If the temperature is too high, they will overripe and discolor. If the temperature is too low, they will be easily frozen. Be careful not to put bananas in the refrigerator, otherwise the flesh will turn dark brown and taste bad. Therefore, put them in a cool and ventilated place when it is hot, and wrap them in newspapers or other items when it is cold.

It is wrong to place bananas like this. Since the pressure surface is too large, the surface of the bananas that come into contact with the table will turn black and then rot. When there are many bananas in the bunch, it is best to have the raised side facing upwards. When there are fewer bananas, such as only a few as shown in the picture, then you have to place them at an angle on one side and eat them as soon as possible.

Tips: Store bananas wisely to extend their shelf life

practice :

1. If you don’t think you can finish all the bananas you bought in a short time, you can rinse the whole bunch with clean water several times;

2. Use a clean rag to wipe off the moisture. The surface should be dry and free of moisture.

3. Use a few sheets of old newspaper to wrap the banana and place it in a ventilated and cool place indoors, making sure the contact area is as small as possible.

Note:

You can also simply hang the bunch of bananas to extend their shelf life.
