how do you prevent bananas from blackening and stay fresh longer?

Answer 1

I usually buy them green and store them in a cool place.

Answer 2

Bananas unfortunately have a limited shelf life like all fresh fruits and will turn black in a few days. Eat them fresh.
You see, when they are transported from where they are grown, they are green and ripening up in a dark and cold container, or are frozen in a freezer, so it is not good to refreeze them anymore. Refreezing will turn the skin black but you can still use the fruit inside for banana bread or banana shakes

Answer 3

When I volunteered in the produce department of my local co-op, the produce delivery guy saw me stocking bananas and was horrified.

Apparently, one should avoid handling bananas at all costs -- only carry them by the stem, and store them where they won't get bumped. He said that if you only touch a banana, that is where the brown spot will develop.

The store got a few days of banana deliveries at once, and they were never stored in the walk-in refrigerator, rather they were stored in a dark cupboard.

Hope this helps!

Answer 4

Try putting them in the fridge, I think the coolness causes them to go a little dormant, worth a shot.

Answer 5

I try to keep them away from apples. Apples release a gas called ethelene (sp?) that promotes ripening of the fruit, whether they are apples or bananas or any other fruit.

Answer 6

I always squeeze lemon juice over the pieces. It keeps them from turning brown:)

Answer 7

I usually wrap them using old newspapers & put them inside the fridge...

Answer 8

Answer 9

Answer 10
