Can you eat bananas with black skins, and can you eat bananas with black skins

Can you still eat bananas if they are black.

If the banana peel is blackened, it will not affect the consumption, but if the flesh is also blackened, it should not be eaten. The blackening of the flesh of the banana is due to the browning reaction, and the place that turns black is the quinone-like substances formed by polyphenol oxidase and the substances in the banana, which are derivatives of benzene and are harmful to the human body, so they cannot be eaten.

Why do banana peels turn black.

In fact, the black turning of the banana peel is not because the banana is poisoned, but because it has been left for too long. There are enzymes in the banana peel cells, and if they are left for too long, the cells will rupture, and the enzymes will be exposed and come into contact with the air and be oxidized to black, resulting in black spots on the banana peel, sacrificing the skin to protect the flesh inside. Therefore, bananas with black spots or blackened on the skin are perfectly edible as long as there is no problem with the flesh.

However, bananas are breathing fruits, once picked, they will ripen quickly, and the ripe bananas should be eaten as soon as possible, and if they are left for too long, causing the flesh to change color, do not eat them again.

When almost all the starch in the banana has been converted into sugar, the flesh will become soft and sweet, and the banana peel will turn completely yellow, and some black spots will appear, or even the whole root will turn black, so it is normal for the banana peel to have spots and turn black, and it is not "the banana is bad" in our eyes. However, it should be noted that what is said here is that the skin is blackened, which can be eaten with confidence, but the inside is that the flesh is blackened, which is really bad and cannot be eaten.

Bananas with black skins, some because the skin of the frozen ones is black, if the inside is good, it is still edible, if there is also a black and rotten situation inside, do not eat it again.

Can you eat bananas with black skin You can eat them in winter, but if the banana peel is frozen, it will turn black.

It's ripe and ready to eat.

If the banana peel turns black and the flesh is normal, then it can be used. If the flesh of the banana turns black, then it is not edible.

If the banana only appears as a darkening of the skin and does not involve the deterioration of the flesh inside, then the human body is edible. The darkening of the epidermis is caused by the blackening of the epidermis due to collisions or oxidation of oxygen when left in the air for a long time. This situation has no effect on the internal flesh, and there is no bacterial growth, so the banana pulp is normal and can be eaten with confidence.

If the flesh inside the banana turns black and soft, it means that the banana has been spoiled and rotten, and a large number of bacteria will breed at this time, which cannot be ingested by the human body, otherwise the bacteria will enter the intestines, which will lead to gastrointestinal dysbiosis, abdominal pain, diarrhea and other adverse symptoms, and in severe cases, it will also lead to food poisoning. At this time, it is necessary to go to the hospital for a physical examination in time and carry out it with the help of a doctor**.

In daily life, people should pay attention to the storage of food, once the phenomenon of food deterioration occurs, immediately discard, and do a good job of cleaning up the corresponding measures.

The banana peel is black, and the inside has not changed color and is still hard, then it is likely that it is too green when it is picked, and then it sprays more ripening agent (usually ethephon or the like), if so, this banana generally tastes worse than the banana that is not ripe, and the ripening agent is also bad for the human body, so it is not recommended to eat.

The blackening of banana peels is actually a manifestation of banana anthracnose, named for the similarity of symptoms to human anthracnose, and the pathogen is banana disc spores, which do not have any effect on the human body. This symptom only manifests itself when the banana is ripe, and the appearance of black spots on the skin indicates that the banana is fully ripe, and the taste and flavor are at their best.

At the same time, unripe bananas contain a lot of tannic acid, which is easy to cause constipation, and the content of tannic acid is greatly reduced after ripening, so it is the best time to eat bananas when dark spots appear on the skin. However, when the flesh is also blackened and rotten, it is not recommended to eat.

Can you eat banana with a "blackened" skin? After reading it, you will understand, don't be "misled" The bananas we buy in the market are generally yellow, but sometimes you may buy some cyan, and after a few days of buying home, it will slowly turn yellow, and some small black spots may slowly grow, and this small black spot will gradually increase, forming a whole black spot.

In fact, these small black spots are the external manifestations of banana anthrax, for this substance, in fact, everyone eats it has no effect at all, only when it is fully ripe, these small black spots will appear on the outer skin, and the banana taste at this time is also the best to eat, and the taste is also very sweet and delicious.

But we should pay more attention to it, that is, if the skin has a large number of black spots, rotten, really don't eat the banana, if it's just some small black spots, you can also eat it with confidence, the banana at this time, the taste is the best.

If the banana peel is black, whether it can be eaten depends on the situation. The blackened banana peel is the appearance of a completely ripe banana. If you peel off the banana and the meat inside is not blackened, the banana is not bad and can still be eaten.

If you peel off the banana peel and find that the meat inside has turned black, it means that the banana has gone bad, and you can't eat it anymore. Eating spoiled bananas may cause gastrointestinal upset, leading to diarrhea.

Bananas are still edible after they turn black. The blackening is because the skin of the banana is damaged, and after encountering oxygen, a black substance is generated, as long as the flesh has not turned black, it will not affect the normal consumption of bananas.

You can eat it, but it is recommended not to eat it, now there should be no shortage of money for a banana, and you can buy a new one.

Banana peels are blackened, and bananas can be eaten.

As we all know, bananas are tropical fruits, so they are still turquoise when picked, and after a long journey to be transported around the country, they gradually ripen, and black spots appear on the skin, similar to the black spots of the leopard. This is because the banana is already ripe, and the appearance of dark spots indicates that the banana is fully ripe. If you eat it at this time, the taste is the best, the sweetness is also very good, some people will choose green bananas when choosing bananas, of course, if you don't eat them immediately, you can choose green bananas for a period of time.

Swift and bright. If you want to buy it and eat it at home, it is recommended to buy some yellow-skinned bananas with black spots, which will taste better. However, it should be noted that if the skin has a large area of black spots and rot, such bananas should not be eaten, and if it is only a few small black spots, it can still be eaten with confidence.

How to see if the banana is ripe or not:

1. You can take a look at the color of the appearance of the banana. If the color of the banana is directly green, it can prove that the banana is not ripe at this time. Or you can look at the banana to see if it has a "plum spot", and if there is, it means that it is ripe.

2. When judging whether the banana is ripe, directly according to the softness and hardness of the banana. When you press it with your hand, you find that you can't press the banana at all, which means that the banana is not ripe.

3. You can judge from the size of the banana. If the banana is still very small, it means that the banana is not ripe.

4. Some naturally ripe bananas are ripe very evenly, and the heart of the banana will not be particularly hard.

A small amount of banana peel blackened can be eaten.

It doesn't matter if there are a few spots on the banana peel, this is because the banana is ripe, and the banana at this time has the best and sweetest taste, so you can eat it with confidence.

Banana peels are blackened in large quantities and should not be eaten.

If there are many black spots on the banana peel, it means that the banana is overripe, and these black spots will seep into the flesh from the banana peel, if the flesh is found to be black, it means that the banana has begun to rot and can no longer be eaten at this time.

In fact, this problem should be analyzed on a case-by-case basis, if the banana only has a little black spot, it can still be eaten, such a banana will be particularly sweet and refreshing, but if it is a large area of black spots and the inside of the banana is also black, do not eat it, because this may contain some harmful substances.

Let's take a look at why bananas are black, first of all, if the banana is left for too long, the inside of the banana will continue to mature and release ethylene, which will adhere to the surface of the banana, and the carbon in these ethylene will break the cell membrane of the banana peel on the surface, and then these carbon elements will be oxidized when they touch the oxygen in the air, and then attach to the banana, which will form black. Secondly, there are some bacteria in the air, and these bacteria and microorganisms will also attach to the surface of the banana peel, at this time, the bacteria will rot because they invade the surface of the banana, so it will appear black.

Then we already know the reason why the banana peel is black, in fact, if it is the first case, it can still continue to be eaten, because in this case it is only the reason why the banana is ripe, on the contrary, it is a good thing, but if it is the second case, it is best not to use it, because bacteria still have certain disadvantages to the human body, but if you peel it and find that the banana inside is not black, you can continue to eat, so that it will not produce harmful substances.

To sum up, there are two different reasons for banana blackening, you must identify what causes bananas to blacken before making a decision, and finally it is recommended that you buy bananas as soon as possible.
