Banana ripening agent is not harmful to human body. Banana ripening agent, scientifically known as ethylene, is not harmful to humans. The natural ripening process of fruits is also the result of their production of endogenous ethylene. Natural ethylene and synthetic ethylene, the molecular formula is the same. In life, if you want bananas to ripen quickly, you can add a ripe apple to the banana and smother it in a bag so that the banana will ripen quickly. This is because the ripe apple releases ethylene on its own. When you eat an apple, you are eating ethylene. Only the apple is natural ethylene and the ripening agent is artificial ethylene. Some people also worry that ethylene, as a plant hormone, will cause premature sexual maturity in people. This concern is even more unnecessary. Plant hormones and animal hormones are completely different, both in terms of molecular formula and mechanism of action. Plant hormones do not have hormone-like effects on the human body, and will not lead to precocious puberty. Therefore, banana ripening agent is harmless to people, we can rest assured to eat ripe bananas.
