If you want bananas to stay fresh longer, the main idea is to slow down the release and spread of ethylene gas — the natural plant hormone that makes fruit ripen.
A common kitchen trick is to store bananas with plastic wrap or reusable wrap around the banana stems.
Why wrapping the stems may help
- Bananas release much of their ethylene gas from the stem area.
- Covering the stems can slow the movement of this gas between bananas.
- This may delay ripening and help bananas stay firm longer.
How to store bananas for longer
- Separate the bananas from the bunch if you want them to ripen more slowly.
- Wrap the stems individually with plastic wrap, beeswax wrap, or another reusable covering.
- Keep them at room temperature away from direct sunlight.
- Keep them away from other ethylene-producing fruits like apples, pears, and avocados.
For even longer storage
- Once bananas reach the ripeness you like, put them in the refrigerator. The peel may turn dark, but the inside usually stays good for several more days.
- Peel and freeze overripe bananas for smoothies or baking.
The “10 days longer” claim is not guaranteed for every kitchen because ripening depends on banana variety, temperature, and how ripe they were when purchased, but stem wrapping can help slow the process.
