Can One Kitchen Item Make Bananas Last 10 Days Longer?
The viral claim is partly true but exaggerated. The “one kitchen item” is usually plastic wrap, used around the banana stems, not the whole fruit.
Bananas naturally produce ethylene, a plant hormone that promotes ripening. Covering the stems may slow the movement/release of ethylene and can delay ripening by several days.
🥇 The simple trick
- Keep the bananas in a bunch, or separate them individually.
- Tear off a small piece of plastic wrap.
- Wrap it tightly around the stem/crown at the top of each banana.
- Keep the bananas somewhere cool, dry and away from direct sunlight.
- Keep them away from other strongly ethylene-producing fruits such as apples and pears.
You don’t need to wrap the entire banana.
⏰ Will they really last 10 days longer?
Don’t count on exactly 10 extra days. Results vary considerably with banana variety, starting ripeness, temperature and storage conditions. Consumer tests report a few extra days from stem wrapping, while some packaging techniques can extend shelf life substantially under controlled conditions.
So the more accurate claim is:
Stem wrapping can slow ripening, but it isn’t a guaranteed 10-day extension.
❄️ Another useful trick
Once bananas are fully ripe, refrigeration can slow further ripening considerably. The peel may turn brown or black, but the flesh can remain firm and edible for considerably longer.
Best approach: 🍌 Buy slightly green bananas → keep them cool and away from other fruit → wrap the stems → refrigerate once they’re at your preferred ripeness.
And if a banana becomes moldy, leaking, fermented-smelling or unusually slimy, throw it away rather than trying to rescue it.
