First, how is the black banana?

As we all know, bananas are tropical fruits. When picked, they are still greenish. After long distances, they are transported throughout the country. They gradually mature and the skin appears black, similar to the black spots of the leopard. Studies have shown that there are two possible causes of blackening.
