Bananas are a fruit that appears in our fruit bowls year-round, so their safety is even more worthy of our attention. Today, the editor will reveal whether blackened bananas are edible.
I. What causes bananas to turn black?
As we all know, bananas are tropical fruits. They are picked green and gradually ripen during their long journey to various parts of the country, causing their peels to develop black spots, similar to the spots of a leopard. Studies have shown that the blackening of the peel can be caused by two possibilities: one is that the chlorophyll fades due to being stored for too long, and enzymes in the banana peel cause it to blacken; the other is that the banana itself is invaded by an anthracnose fungus that is not pathogenic to humans, causing it to turn black.
II. A guide to eating bananas
It is well-known that bananas promote intestinal peristalsis and have a laxative effect, but green bananas do not have this function. Because green bananas contain tannic acid, consuming them is not conducive to the absorption and utilization of other nutrients, so it is better to choose ripe bananas. In addition, bananas should not be stored in the refrigerator, as this will cause them to blacken more easily and affect their texture.
Ripe bananas should be eaten as soon as possible. If left for too long, the flesh will change color and should no longer be eaten. The flesh of the discolored banana has decomposed other nutrients, greatly reducing its nutritional value.
