How to Store Bananas. Half the world eats bananas raw and sweet, while the other half cooks it as a starchy vegetable. Whichever way you choose to partake of this tropical fruit, careful storage can make bananas all the more enjoyable.
How to Store Bananas
Leave bananas in a closed paper bag at room temperature if they are not yet ripe.
Place an apple in the bag to speed ripening. The apple gives off ethylene gas, which causes fruit to ripen.
Once bananas become ripe – that is, yellow in color, speckled with a bit of brown – put them in your refrigerator, preferably at a temperature of about 50F (10C).
Store for no more than 2 weeks.
Once cut, sprinkle with citrus juice to stop them from browning too quickly.
