If you’re using this as a health/lifestyle article headline, the claim needs a little caution: there isn’t a kitchen item proven to make bananas last exactly 10 days longer for everyone. A useful method is to wrap the banana stems with plastic wrap to slow ripening.
Bananas Can Last Longer With One Simple Kitchen Item
Bananas naturally release ethylene, a plant hormone that accelerates ripening. As bananas ripen, they produce more ethylene, which can cause the fruit to soften and develop brown spots more quickly.
One simple trick is to use plastic wrap around the stems.
How to do it
- Separate individual bananas from the bunch if you want to slow ripening.
- Wrap the exposed stem ends tightly with a small piece of plastic wrap.
- Keep the bananas at room temperature, away from direct sunlight and heat.
- Check them regularly and remove any banana that becomes overripe.
The plastic wrap can reduce the movement of ethylene around the stem and may slow the ripening process, although the effect varies. It isn’t guaranteed to add 10 days of shelf life.
What about the refrigerator?
Once bananas are ripe, refrigeration can help preserve the edible fruit for longer. The peel may turn dark brown or black because of the cold, but the inside can remain perfectly usable.
Keep bananas away from other ripening fruit
Apples, pears, avocados, and some other fruits also produce ethylene. Keeping bananas separated from particularly ethylene-producing fruit may help slow their ripening.
Don’t refrigerate green bananas
Cold temperatures can interfere with normal ripening. If your bananas are still green and you want them to ripen naturally, keeping them at room temperature is generally better.
The takeaway
You don’t need an expensive banana-storage gadget. Wrapping the stems with plastic wrap, keeping bananas away from heat and direct sunlight, and refrigerating them once ripe are simple ways to potentially extend their usable life.
And if someone claims that one kitchen item will guarantee that bananas last exactly 10 days longer, treat that claim skeptically—the actual shelf life depends on the banana’s ripeness, temperature, variety, and storage conditions.
