While it might seem logical to store bananas in a fruit bowl, this often leads to them softening and ripening too quickly. I’ve started keeping mine on a corner of the kitchen countertop, where they stay fresh for up to a week longer.
I’ve also found an even more effective method for extending their shelf life: I recently discovered that bananas release ethylene gas from their stems. So, wrapping their stems in aluminum foil or plastic wrap helps keep them fresh for weeks.
Aluminum foil or plastic wrap creates an airtight seal around the stems, trapping the ethylene gas and preventing it from circulating into the air.
Don’t make the mistake I did by using parchment paper I’ve learned that it doesn’t work, as it can’t form a proper seal to contain the ethylene gas.
About two weeks ago, I tested this method on a newly bought bunch, and after 10 days, the bananas were still fresh. With just a bit of aluminum foil, they lasted nearly two weeks longer than they would’ve in a fruit basket.
