Bananas look like the moon in the sky.
It has a sweet and soft taste and is ready to be eaten when peeled. It is called “happy fruit”.
When picking bananas, a careful person may find a problem, that is, some bananas are straight, and some bananas are curved. To tell the truth, after eating bananas for so many years, even the straight bananas are a little curved.
So, why is the shape of the same banana different?
Why are bananas bent?
In fact, the banana is straight from the beginning, not bent! !
As we grow up, and the need for sunlight becomes stronger and stronger, this time is affected by a part of gravity, and because of the positive direction, this kind of positive direction makes the bananas try to tilt upwards in order to absorb more sunlight. It became curved.
In addition, the more sunlight the banana receives from the outside, the greater the bend; the less sunlight from the inside, the smaller the bend.
Choose straight or curved bananas?
Knowing the growth principle of bananas, we found that curved bananas absorb more sunlight and have longer exposure time. We also know that the sweetness of fruits is proportional to the time of light. Therefore, curved bananas taste better and taste better. Fragrant and sweet; straight bananas have less light, so the taste and sweetness will be slightly worse.
Straight bananas are usually picked before they are ripe, and the taste will be jerky, so when we buy bananas, it is better to buy curved bananas.
Speaking of this, some people may be wondering. The straight bananas are picked when they are immature. Why are the straight bananas on the market also yellow?
The straight bananas we saw were all ripened.
Due to the long distance of transportation, bananas are a kind of fruit that is not easy to preserve. Therefore, local fruit farmers choose to pick the bananas when they are half-ripe and then sell them to vendors. In this process, the bananas will not naturally turn into bends. Instead, after ripening and time, it gradually turns into yellow, which is the straight yellow banana that we often see.
All in all, the difference between a bent banana and a straight banana is not only in terms of taste and texture, but also whether it is naturally ripened or not. If they are all straight bananas, it does not matter if they are bought and eaten, because the ripening agent of bananas is in compliance with national standards.
How to preserve bananas?
Bananas that can’t be eaten must be kept well, otherwise they will turn black and go bad in a day or two.
practice:
Step 1: Rinse the banana several times with clean water first, in order to clean the ripening agent on the surface of the banana.
Under the same external conditions, the washed banana can be stored for 5-7 days without deterioration~~
Step 2: After cleaning, wipe off the moisture on the banana surface.
Step 3: Take a piece of tin foil and wrap the banana handle.
This is because the banana stem is the place where the most ethylene gas is released, and the foil wrap can prevent the diffusion of ethylene and extend the storage time of the banana.
If you don’t have tin foil at home, you can also use plastic wrap.
Finally, we took out a rope, passed through the banana handle, and stored the banana in a cool and ventilated place at home. The bananas preserved in this way will not be damaged after eating for a week.
Why hang up bananas?
When the banana is laid flat, the entire weight is pressed on the contact surface, and the pressure on the contact surface becomes greater. It is likely to break some cell membranes of the epidermal cells on the contact surface, causing the oxidase inside to flow out, causing an oxidation reaction Dark spots.
Therefore, it is best to hang the bananas you bought back to reduce the pressure area, so that the bananas can be “beautiful” longer.
Does the banana peel turn black mean that the banana is broken?
Can blackened bananas be eaten?
Yes. You don’t eat banana peels.
There are three reasons why bananas turn black:
Reason 1: Bananas have been stored for a long time. As time changes, bananas will release ethylene gas, which causes the color of bananas to become darker and yellower, until a lot of spots are produced and the skin becomes black.
Reason 2: The banana itself has deteriorated, and such bananas cannot be eaten.
Reason 3: When bananas have experienced a lot of bumps or have been stored for a long time, with the help of oxygen in the air, it is easy for the polyphenol oxidase in the banana to react with oxygen, thereby turning the banana skin black.
The first and third reasons blackened bananas can be eaten with confidence as long as the flesh is not blackened and is not exposed to the air.
And the kind of banana with black spots means it has matured. At this time, the banana tastes very good and the effect of nutrient absorption is higher.
In addition, bananas that are not fully ripe should not be put in the refrigerator, or you will just wait for it to turn black soon. Generally speaking, bananas can be stored at room temperature, there is no need to put them in the refrigerator.
