The claim that bananas last “10 days longer” when stored with one kitchen item usually refers to a simple trick: wrapping the banana stems with plastic wrap (cling film) or reusable food wrap.
How the trick works
- Keep bananas together or separate them (either can work depending on conditions).
- Wrap the stem ends tightly with a small piece of wrap.
- Keep them at room temperature, away from direct sunlight and heat.
Why it may help
Bananas naturally release ethylene gas, which speeds up ripening. Covering the stems may reduce the amount of ethylene escaping and can slow ripening.
Other ways to keep bananas fresh:
- Keep bananas away from other ripe fruits like apples and pears, which also release ethylene.
- Hang bananas or store them where they won’t get bruised.
- Once they reach your preferred ripeness, refrigerate them—the peel may darken, but the fruit inside can stay good longer.
- Freeze overripe bananas for smoothies or baking.
The exact “10 extra days” depends on the banana variety, temperature, and storage conditions. The trick may help extend freshness, but it won’t stop natural ripening completely.
