Keep them Cool
An excellent way to keep your bananas ripe for longer is to store them in the fridge once the peels start losing their yellow color. A lower temperature will help preserve the fruit’s freshness, so even if the banana’s outside is a little brown, the fruit itself will still be delicious.
Wrap Up Those Stems
The chemical compound, ethylene, is responsible for the ripening of bananas and is released from the stems of the fruit. Fortunately, you can slow the release of this gas if you wrap the stems. You can use saran wrap and cover each one firmly, which will buy you an extra few days of banana goodness.
If you like bananas in slices, consider squeezing some citrus juice on them. By doing this, you’ll slow down the oxidation process. If you store them in an air-tight container in the fridge, it’s a great way to preserve them if you don’t wish to eat the slices immediately away.
Another way to stop ethylene from acting so quickly is to put the bananas on a hook. By doing this, you will allow a higher flow of oxygen around the fruit, holding back some of the ethylene. This will also prevent the bananas from bruising.
Avoid Other Fruits
Many fruits produce ethylene gas, so it’s a smart idea to keep all your fresh produce distant from one another. Doing this will prevent your bananas, and the rest of your fruit for that matter, from rotting sooner than need be.
