The claim that “bananas last 10 days longer when stored with one kitchen item instead of in a fruit bowl” is a common food-storage tip, but the results depend on the method and your environment.
One popular trick is to use plastic wrap or reusable wrap around the banana stems. Bananas release ethylene gas, which speeds up ripening. Covering the stems may slow the release of some ethylene and can help bananas stay firm a little longer.
Other ways to extend banana freshness:
- Keep bananas away from other ripening fruit (such as apples, pears, and avocados), which also release ethylene.
- Store them at room temperature until they reach your preferred ripeness.
- Separate the bananas from the bunch to slow ripening for some people.
- Refrigerate ripe bananas — the peel may turn dark, but the inside can stay good longer.
- Freeze overripe bananas for smoothies or baking.
A “10-day extension” is not guaranteed, but reducing ethylene exposure and controlling temperature can noticeably slow the ripening process.
