If you want to prevent your bananas from turning brown quickly, here are few tips from www.tasteofhome.com.
Buy green bananas. The easiest way to prolong your bananas’ shelf life
Hang your bananas. Ethylene gas is released through banana stems when picked. Hanging them slows down the gas.
Wrap banana stems in plastic wrap. This will also slow the gas released through banana stems.
Freeze your bananas. This is a good way to preserve for future use.
Place ripe bananas in the fridge. The cool temperatures will keep them from ripening further (for a few days at least).
Buy a banana keeper. This will protect your bananas from bruising, which causes squishy parts and speeds up ripening.
