The viral claim that bananas last 10 days longer because of one kitchen item usually refers to plastic wrap—specifically, wrapping the banana stems.
🍌 Why it can help
Bananas naturally release ethylene gas, a plant hormone that accelerates ripening. Much of the gas is released around the stem.
Loosely wrapping the stem/crown with plastic wrap can slow the movement of ethylene around the fruit and may modestly delay ripening.
The best way to store bananas
- Keep them away from direct sunlight and heat.
- Once they’re at the ripeness you like, putting them in the refrigerator can slow further ripening. The peel may turn brown or black, but the fruit inside can remain good.
- Keep bananas away from other ethylene-sensitive produce if you want to slow ripening.
- A banana hanger can help prevent bruising, but it isn’t magic.
- Wrapping the stems can help somewhat, but “10 days longer” isn’t guaranteed—temperature, ripeness, variety, and handling all matter.
One important point
Don’t seal green bananas in an airtight plastic bag at room temperature; trapped moisture can encourage deterioration.
So, if the “one kitchen item” in the post is plastic wrap, there’s a reasonable biological explanation for the trick—but the dramatic 10-day guarantee is mostly clickbait.
