Bananas can stay fresh for up to two weeks if stored correctly, according to a food hygiene specialist. The key is to keep them on a worktop, not in a fruit bowl or plastic bag.
Why Bananas Ripen Quickly
Bananas produce ethylene gas, which accelerates ripening. When kept in a plastic bag, this gas builds up and causes brown spots to appear within a day or two. Many retailers are phasing out plastic packaging, but perforated bags still make bananas ripen faster.
Best Storage Practices
The specialist at High Speed Training advises keeping bananas at room temperature, away from dampness, direct sunlight, and heat sources like ovens. Separating the bunch and wrapping the stems in plastic wrap or cling film can also slow ripening, as the gas is released from the stem.
For those who find wrapping time-consuming, a banana tree is a good alternative to keep fruit well-ventilated. Once bananas reach optimal ripeness, refrigerating them can extend freshness for up to two weeks.
Overripe Bananas Are Still Useful
Browning or overripe bananas are still edible inside. They can be frozen and used in smoothies or banana bread, reducing food waste.
