Can a blackened banana still be eaten? There were two different situations, but today I finally know.

Life

There are two kinds of blackening of bananas, one is the blackening of banana skin, the other is the blackening of banana meat. For the case of banana skin blackening, we know it is the action of anthrax. However, anthrax is a harmless bacterium, which is harmless to human health, not to mention only on the epidermis. Therefore, only the banana skin blackening is completely edible. As for banana meat blackening, because the blackening component is quinone-like substances, although harmful to human body, it is relatively small. Therefore, bananas can continue to be eaten if there is no widespread blackening of the pulp.
