Because all fruits emit a gas which is known as “ethylene”, they are able to help other fruits ripen more quickly. By simply putting an apple next to a banana in a brown bag, you will be able to see just how quickly it ripens in comparison to being left alone out in the open.

A lot of people use other fruits such as apples and oranges to ripen up their bananas so they can be eaten sooner rather than later.

If you are one of the many people who hate waiting for their bananas to ripen, it might be a good idea to try putting an apple in with the ones you buy from the store.
