Can you eat bananas when they turn black, and can you still eat bananas when they turn black

If only the skin of the banana is blackened, the flesh is not blackened and can still be eaten. When a banana comes into contact with the air, it will slowly be oxidized and blackened, which is actually a manifestation of oxidation, so it can be eaten if the skin is blackened.

Bananas are very ripe and are almost always green when they are shipped from the place of production, and they are not ripe at all. This is all because there is a special preservative for fruits, if we eat these fruits with preservatives, it will cause this chemical to remain in our body, so we have to wait until the bananas are ripe before eating, so as to reduce the risk.

Banana consumption is contraindicated.

1. It should not be eaten on an empty stomach.

Magnesium affects heart function and has an inhibitory effect on the cardiovascular system. Bananas have more magnesium, and eating them on an empty stomach will destroy the balance of magnesium and calcium in the human blood, which is not conducive to good health.

2. Do not overeat.

Bananas are rich in magnesium, potassium and other elements, and eating too many bananas in a short period of time will cause a sharp increase in the content of magnesium and potassium in the blood, resulting in an imbalance in the proportion of elements and harmful to health. Eating more bananas may also greatly reduce gastric acid secretion, leading to gastrointestinal disorders and excessive mood swings.

3. Unripe bananas should not be eaten, and unripe bananas contain a large amount of tannic acid, which has a very strong astringent effect, which can form dry and hard feces and cause constipation.

The taste of bananas is known to be very good, and sometimes it can help us get rid of the disease, especially for patients with constipation, bananas are like a good medicine, although they cannot be directly **, but also can play an auxiliary ** effect. In ordinary life, we see that many bananas are actually black on the outside, and the meat inside may also be black, so can you eat bananas when the inside is black?

Can you eat bananas with black hearts?

If you open the banana and find that the flesh in the middle is black, it is best not to eat, the blackened part is mainly caused by local mildew or bacterial infection caused by too long storage, and it is easy to cause acute gastroenteritis after eating.

If there is only a very small black heart, it can be eaten normally, which is normal, the world's earliest banana not only has seeds, but also many and large, but very little flesh (wild banana seeds are very large and hard, and it is very inconvenient for people to eat it). Although bananas are generally eaten as fruits in China, bananas are eaten in a variety of ways in countries such as Central and South America and Africa, even their grains and vegetables. Therefore, people pay attention to the cultivation of banana varieties.

In the long-term artificial cultivation, bananas with fewer fruits and more seeds are eliminated, leaving those with fewer seeds and more fruits.

After further improvement and cultivation, it became the banana it is today: the flesh has increased, the seeds have degraded, and they have become more sweet and fragrant. The resulting banana has no seeds, and what little bit it bears degenerates into rows of small brown dots that cling to the center of the flesh, forming the black core in the flesh.

In addition, unripe bananas are not recommended to eat, because raw bananas contain a large amount of tannic acid, which has a very strong astringent effect and can form dry and hard stool in the stool, thus causing constipation. The most typical is that after eating bananas, the elderly and children can not only help laxative, but can cause obvious constipation.

Banana peels turn black and edible, while banana cores turn black and inedible. During the ripening process of bananas, ethylene is released, which has the effect of ripening fruits. When black spots appear on the banana peel, it usually means that the banana beam chain has been completely ripe and is gradually rotting, and the banana should be eaten immediately.

If there are too many black spots on the banana peel and the banana core is black, it is a sign that the banana has rotted and it is best not to eat it, so as not to cause physical discomfort. <

Banana peels turn black and are edible, while banana flesh turns black and inedible. During the ripening process of bananas, a gas called ethylene is released, which has the effect of ripening fruits. As the banana matures, more and more ethylene is released, and the surface of the banana turns black.

The faster the ethylene is produced, the faster the banana will ripen, and the skin will get darker and darker. When black spots appear on the banana peel, it usually means that the banana is completely ripe and gradually rotten, and the banana should be eaten immediately. If there are too many black spots on the banana peel and the flesh inside the banana is black, it is better not to eat the banana if it is rotten, so as not to cause physical discomfort.

The flesh inside the banana turns black because the banana is not edible when it goes bad.

The banana is edible when the blackened part of the banana is a black line, which is formed by the seeds of the banana. Once the flesh of the banana has turned black, the blackened part can be removed and the normal part can be eaten.

1. The flesh turns black.

The inside of the banana may turn black because it has been left for too long, or it is in contact with the air after peeling, at this time, the banana reacts with the air, and the ingredients have also deteriorated, so they are not edible.

2. A black line appears.

There will be a very thin black line inside the banana itself, which is the metamorphosis of the banana seed, and if the blackened part of the banana is here, then it can be eaten.

3. How to eat.

When eating bananas, the black part of the banana appears, so you can remove the black part and eat the healthy part. If you accidentally eat the blackened part of the banana, if there is no obvious discomfort, it is recommended to drink plenty of hot water to speed up the discharge of waste products from the body. In case of diarrhea, vomiting, constipation or even food poisoning, it is advisable to go to the hospital immediately.

If the flesh of the banana has turned black, do not eat it, spoiled fruit is not good at all, it will only have a negative effect.

But it doesn't matter if the banana peel is black, as long as the meat inside is good, you can eat it. Anthrax can cause bananas to appear as dark spots. Anthrax is a fungal disease caused by the bacillus spp. bananas, a fungal disease that only manifests itself when bananas are ripe.

It's just that anthrax will make bananas spotted, and bananas will turn black after being left for a long time. This is because the epidermal cells of bananas contain a kind of carbon oxide, and usually, the cell membrane tightly wraps and protects the carbon oxide, just like the human body protects flesh and bones.

Once it is bumped, or frozen at low temperatures, the cell membrane will break. The carbon oxide inside comes into contact with the oxygen in the air, and when the oxidation of oxygen turns black, some small spots naturally appear.

This kind of banana that looks ripe on the outside but still has a hard core on the inside is because it was picked too early and is not a diseased banana. The taste and sweetness of bananas are not only related to the variety of bananas, but also to the time of picking. Bananas take a long time to ripen in winter and accumulate more sugar, so bananas bought in spring will be sweeter, while bananas in summer grow faster and accumulate less sugar, so they are not sweet.

Bananas can be picked when they are ripe, but the banana planting base picks them when the bananas are ripe at five, which leads to the fact that the inside of the banana cannot be fully ripe, even if it is ripened in the later stage, it can only make the outside look ripe, and there is still a hard core inside the banana. Picking in advance can sell for a good price, but if you wait until the peak season to pick the bananas, it will not sell. It is understandable for individual growers to pick in advance in order to catch up, but this will lead to unripe bananas on the outside and unripe on the inside, and the taste is poor.

Ripening bananas with ethephon:

When picking bananas, there will be two large pools in the banana orchard, one pool puts clean water to clean the bananas, and the other puts preservatives, after the bananas are picked, they need to be soaked in the clear water pool and the preservative pool successively, and then sealed in a plastic bag and extracted the air in the bag, so that it can be packed and shipped to all parts of the country. Once the bananas arrive at their destination, they are placed in a warehouse, and the wholesaler determines how many boxes of bananas to ripen based on the daily sales volume. If you can sell 1,000 boxes of bananas a day, you can pick 1,000 boxes of bananas in the warehouse and put them in the boxes to ripen them.
