HOW TO KEEP BANANAS FRESH
Glad Cling Wrap
Separate each banana from the bunch.
Wrap each stem in plastic cling wrap.
…simple enough, right?
Wrapping your bananas in cling wrap will help slow the ripening process and keep your bananas fresh for 3-4 days longer than if you don’t wrap them. And I am not just making this stuff up, here is the science behind it:
BANANAS, LIKE MANY FRUITS, NATURALLY RELEASE THE GASES THAT CONTROL BROWNING AND RIPENING. MUCH OF THE GASSES ESCAPE FROM THE STEMS, OR THE CROWNS, SO BY WRAPPING THE CROWNS, YOU ARE ABLE TO SLOW DOWN THE RIPENING PROCESS A BIT.
