Ripening is an indispensable link in the banana industry chain, which is widely used all over the world for a hundred years, and the use of ripening agents is not excessive and harmless to the human body. Experts said that ethephon, as a ripening agent, is widely used in banana ripening, and there are strict restrictions on the amount and interval between uses. Since bananas are transported long distances, green fruits must be picked, and bunches of bananas cut from the trees are difficult to ripen, and most of them will rot if ethephon is not used.

Therefore, normal ripening of bananas will not produce substances harmful to human health, while excessive use is harmful to human health.
