The “one kitchen item” is often claimed to be plastic wrap, used around the banana stems. 🍌
Why it may help
Bananas naturally produce ethylene, a plant hormone that speeds ripening. Wrapping the crown/stems can reduce the movement of ethylene around the fruit and may slow ripening somewhat.
For best results:
-
Separate bananas from the bunch if you want to slow ripening.
-
Wrap the stem/crown with a small piece of plastic wrap.
-
Keep unripe bananas at room temperature, away from direct sunlight.
-
Once ripe, refrigeration can extend the edible life. The peel may turn dark, but the flesh can remain good.
-
Keep bananas away from other ethylene-sensitive produce when possible.
The claim that this method will always add exactly 10 days isn’t reliable. Storage temperature, starting ripeness, banana variety, and handling all affect how long they last.
If you want a plastic-free method, hanging bananas on a hook and keeping them in a cool, well-ventilated spot can also help prevent bruising and premature ripening.
