Not all that simple.... Green bananas (never quite
sure when to stop the anananan) will stay green after
picked for awhile, but they won't stay green
indefinately. They will either ripen (helped along
with Propylene gas- the only plant hormone known to
exist as a gas in nature) or if left too chilled, turn
an ugly grey, followed by an even uglier black.
Grocers know not to delay ripening bananas by cooling
them, instead they open the boxes and tear off the
plastic to vent off the Propylene gas, giving another
24 hours or so of ripening delay.
