Bananas are a staple in most households, but they can spoil quickly and turn brown and spotty within a day or two - especially when stored in a fruit bowl. However, a simple trick involving tin foil can extend their freshness for up to 14 days.
Why Bananas Spoil Quickly
Bananas produce a natural gas called ethylene, which accelerates ripening. When kept with other fruits, they release so much ethylene that it can cause neighboring fruit to rot rather than ripen. Storing bananas in a fruit bowl is a common mistake that leads to rapid spoilage.
The Stem Foil Method
To keep bananas fresh, separate the bunch and wrap each stem tightly with tin foil. This blocks the ethylene gas emitted from the stems, slowing the ripening process. Place the wrapped bananas on a plate away from heat sources like the hob, air fryer, or windows.
In tests, bananas remained yellow for 10 days, developed slight marks on day 11, and only began browning on day 14. Tin foil works better than cling film or baking paper because it creates a secure seal without trapping moisture.
This method takes about 30 seconds and can save money by reducing fruit waste. Try it to enjoy fresh bananas for longer.
