What causes bananas to ripen?

the different stages of bananas ripening

Bananas are an ethylene-producing food, which is the reason why this fruit goes through a ripening process. The ripening process typically takes one to seven days depending on the environment and current state of the fruit. For example, green bananas are underripe, so they’ll take a bit longer to ripen vs. a bright yellow banana. Thankfully, there are different methods to speed up the ripening process.

Tip: Bananas are ripe when they are yellow in color with some brown spots and are soft yet still hold their shape. The more brown spots a banana has, the sweeter it will be. Overripe bananas are fully brown and soft, and are often used in baked goods.

How to store ripe bananas

Bananas are fairly delicate and can bruise easily. Store your bananas in an area of your kitchen where they won’t be in any harm. Keep them on the counter until they reach peak ripeness. You can then store ripe bananas in the fridge to keep them from spoiling. Don’t worry if the peels start blackening — the inside of the bananas should remain soft and ripe for a few days. If they start browning, you can freeze them to use for smoothies and other banana recipes.
