What Freezing Does to Bananas

Because of their many uses and nutrients, it's a no-no to let these fruits go to waste. If you find yourself with more bananas than you can consume, it's always a good idea to freeze them to keep them from going bad.

Freezing is a great way to extend the shelf life of these sweet and nutritious fruits. It is recommended that you freeze ripe to slightly overripe bananas. They will stay in this state in the freezer because the low temperature, controlled humidity, and absence of air stop the fruits' ripening process. This favorable environment keeps them from turning brown, preserves their freshness, and helps maintain their nutrients.

But just when you thought these fruits can't get any better, freezing them makes them even sweeter! Once you thaw frozen bananas, they diffuse starches and the amylase enzyme and this leads to the conversion of these starches to sugar. Defrosting activates the release of all the confined sugars and juices which is why thawed bananas taste even sweeter!

Why do bananas turn brown in the freezer?

If you have experienced seeing a banana that turned brown while it was kept in the freezer, it means that air was able to enter inside its container. The chemicals in the bananas react with the oxygen in the air. This is called oxidation which causes the tropical fruit to turn brown. This is why it is important to make sure that the containers are airtight or the freezer bags are sealed well so that no air can pass through.
