Why Do Bananas Bruise?

In order to understand banana bruising, let’s take a peek at the banana’s ripening process. Meet ethylene. Ethylene is a hormone found in the peel of the banana once the banana is fully developed. It is responsible for modifying the taste, color, texture, and softening of the fruit.

When you buy a bunch of unripe green bananas at the grocery store, time and ethylene transform them into delicious, golden bananas. As ethylene is produced by the banana, it makes the fruit taste sweeter and less tart, it changes the color of the fruit from green to yellow, and it softens the fruit.

Unfortunately, ethylene has no stop button. When left uneaten, the ripening process will continue until the banana takes on a “bruised” appearance and eventually turns black.

You can’t prevent the ripening process from occurring, but one way to slow it down is by placing bananas in a cool location. You should also remove them from the bag when you bring them home from the market. Leaving bananas in the bag allows ethylene gasses to build up, causing the bananas to ripen very quickly.

This knowledge can work to your advantage, too! If you have a craving for a banana and the bunch is still green, placing a banana in a sealed bag will speed along the ripening process. Your sweet snack should be ready to eat in about 24 hours.

It’s important to remember to keep bananas out of the fruit bowl and away from other fruits if you want to delay ripening. If you place your bananas in a bowl with other fruits, such as apples or tomatoes (which also rely on ethylene for ripening), you may be surprised by what happens.

Ethylene released by neighboring fruits in the bowl can actually ripen your bananas! In fact, this is where the expression “one bad apple spoils the bunch” comes from. If one apple in a barrel begins to over-ripen and rot, it will cause the surrounding apples to do the same.

This is why fruit farmers pick and ship fruit when it’s still green, long before the ripening process has begun. Shipping under-ripened fruits ensures they are verging on peak ripeness when they hit the grocery shelves — and perfectly delicious by the time they finally reach your dinner plate.
