You can freeze bananas unpeeled however it's best to peel the bananas before freezing them.
If you freeze the bananas without peeling them first the banana peel becomes harder to remove from the frozen banana and the banana peel also turns brown and the banana can become mushy.
The banana is still safe to eat this way but they are less tasty and it's much easier and better to just peel the bananas first and then freeze the banana whole or sliced in a bag or freezer safe container.
You can also use tin foil or aluminum foil to keep bananas fresh at room temperature for a month or two before they go bad.
The best way to keep bananas fresh for a long time is to take some tin foil or aluminum foil and wrap each individual banana in the foil.
When the bananas are wrapped in the aluminum or tin foil they should keep for up to 1 to 2 months before they start going bad.
You won't be able to keep bananas longer than a few months before they get less fresh and begin going bad.
But you can cut up the bananas and then freeze the sliced up bananas and they will keep in the freezer for a year and sometimes longer.
However if you freeze the bananas they will not be as tasty or fresh.
Bananas are best eaten while fresh and within a month of purchasing them.
But wrap the bananas in some tin foil or aluminum foil or even some plastic wrap to keep them fresh for longer than they normally would.
