Black spots began to appear on the banana skin, which is a sign that the banana is "ripe". There are a few black spots, which are "edible and have nothing to do with safety". Moreover, bananas at this time are very sweet and taste better, so just eat them as soon as possible.

But Xu Yongxin warned that if there were too many black spots on the banana skin, the banana would be overcooked, and the black spots would enter the flesh from the skin. Peel off the banana skin, and the pulp inside is black, so the banana is seriously rotten and can't be eaten any more.

In addition, some people call bananas with black spots on their skins "sesame bananas". Xu Yongxin said that in a strict sense, there is no such banana name. Banana varieties that people often buy in the market will have black spots on their skins when they are ripe.

As for the storage method of bananas, Xu Yongxin said that bananas are tropical fruits, so it is best to store them indoors in a cool, dry and ventilated place with a slightly higher temperature. Bananas can't be refrigerated in the refrigerator, otherwise they will be frozen and the flesh will turn dark brown.

Anyone who has eaten bananas with dark spots will find that bananas with dark spots are sweeter. Although they are not very beautiful in appearance, they are sweeter than "beautiful" bananas. Some friends will buy yellow bananas specially and eat them at home after dark spots appear, which will not affect their health.

As we all know, bananas are high in nutrition, low in calories, rich in protein, sugar, phosphorus, potassium, vitamins A and C, and rich in dietary fiber, so they are quite good nutritious foods. Looking at its appearance, it can be divided into bright yellow, pan-green, yellow and spotted.

Many people mistakenly think that bananas with black spots are "bad", but in fact, normal bananas will turn black when they are ripe. The pathogen causing anthracnose invades the fruits before they are ripe. If there are small black spots, it proves that bananas are completely ripe, and the taste is generally the best.

this kind of black spot has no effect on banana meat. Bananas are not so good fruits. If you don't finish them in three or two days, their skins may start to grow black spots and turn black. Bananas grow black spots, which is actually a very common phenomenon.

The reason why bananas grow black spots is that bananas also suffer from diseases, such as yellow leaf disease, anthracnose, scab, flower thrips, fruit cracking and so on. Among them, suffering from anthrax will make bananas show black spots. Anthracnose is a fungal disease caused by Colletotrichum banana.

Although bananas are good, you should not eat more. Just eat 1-2 bananas a day. Bananas are high in sugar and potassium (excreted through renal tubules), so people with high blood sugar and renal insufficiency must eat less. In addition, banana collocation is also taboo, and it should not be eaten with yogurt and potatoes, otherwise it will do some harm to human health.
