Bananas go bad fast because of ethylene gas, which they release as they ripen. They’re picked green and ripened with extra ethylene before they get to the store, speeding up the process. Bruises make them ripen even faster.
To keep bananas fresh longer, try this simple trick:
Someone on Reddit wanted to know how to keep bananas from going bad before they could eat them all, since they only shop once a week.
One person suggested freezing them for smoothies or ice cream. Another suggested buying bananas at different stages of ripeness.
Someone else mentioned wrapping the stem of each banana (or the whole bunch) in plastic wrap or foil to slow down the release of gas
.
Wrapping the stems can keep bananas fresh for up to a week. Separating the bananas first works best. Some say this keeps them fresh for almost two weeks, but it depends on how ripe they were to begin with.
If your bananas are already ripe, putting them in the fridge can help them last, even if the peel turns brown.
Hmmm God help us
