What chemicals are involved to make the banana ripen faster?

Ethylene is the chemical that causes bananas to ripen. It is a plant hormone that is produced naturally by all fruits and vegetables. Ethylene gas is produced in large quantities by ripe bananas, and it can cause other bananas in the same vicinity to ripen more quickly.

The process of banana ripening is triggered when the banana is exposed to ethylene gas. The ethylene gas binds to receptors on the banana's surface, which then causes a series of biochemical changes to take place. These changes include the breakdown of starch into sugars, the production of flavor compounds, and the softening of the banana's flesh.

Ethylene gas can be used to artificially ripen bananas by placing them in a closed container with a ripe banana. The ripe banana will release ethylene gas, which will cause the other bananas in the container to ripen more quickly.

Ethylene gas is also used commercially to ripen bananas. Bananas are typically harvested when they are still green and hard. They are then placed in ripening rooms where they are exposed to ethylene gas. The ethylene gas causes the bananas to ripen quickly so that they can be shipped to stores and sold to consumers.
