The headline “Bananas Last 10 Days Longer When Stored with One Kitchen Item Instead of in a Fruit Bowl” has a real storage trick behind it, but the “10 days longer” claim isn’t guaranteed. How long bananas last depends on their ripeness, temperature, variety, and storage conditions.
🍌 The kitchen item: aluminum foil
A useful trick is to wrap the banana stems/crown with a small piece of aluminum foil. Bananas naturally produce ethylene, a plant hormone that promotes ripening. Covering the stems may slow the release and spread of ethylene. A 2026 kitchen test found foil-wrapped stems performed particularly well among the methods tested. (Kitchn)
How to do it
- Buy bananas that aren’t already heavily spotted.
- Keep the bunch together or separate it—either can work.
- Wrap just the stems/crown, not the entire fruit, fairly snugly with foil.
- Keep the bananas somewhere cool, dry, and out of direct sunlight.
- Keep them away from other ethylene-producing fruits such as apples and avocados. (food.unl.edu)
🧊 What about the refrigerator?
Once bananas have reached the ripeness you want, refrigerating them can slow further ripening. The peel may turn brown or dark, but the flesh inside can remain at its ripe stage. Don’t refrigerate unripe bananas if you want them to ripen normally. (food.unl.edu)
Bottom line: The foil trick is reasonable and inexpensive, but “10 days longer” is not a universal result. The biggest factors are controlling temperature, avoiding bruising, and managing exposure to ethylene.
