To best store bananas, separate them from the bunch, wrap the stems tightly with plastic wrap, and store them at room temperature away from direct sunlight and heat. This slows down the ripening process.
Bananas release ethylene gas, which accelerates ripening. The stems are the primary source of this gas. Here's a step-by-step breakdown of the ideal storage method:
Separate the Bananas: Gently detach each banana from the bunch. This prevents the ethylene gas from affecting the entire group.
Wrap the Stems: Tightly wrap the stem of each banana with plastic wrap. This creates a barrier that significantly reduces the release of ethylene gas.
Store at Room Temperature: Place the wrapped bananas on the counter, away from direct sunlight, heat sources (like ovens or radiators), and other fruits that also produce ethylene gas (such as apples and avocados). Avoid refrigerating unripe bananas, as this can damage them and prevent them from ripening properly.
Refrigerate Ripe Bananas (Optional): Once the bananas are ripe to your liking, you can refrigerate them to extend their shelf life. The peel will turn brown in the refrigerator, but the fruit inside will remain edible for a few more days.
Don't store bananas in a closed bag or container. This traps the ethylene gas and speeds up ripening. If you want to slow down ripening even further, consider using a banana hanger, which promotes airflow around the fruit.
