To freeze a banana properly, peel the banana, cut it into slices, place the slices on a baking sheet lined with parchment paper, and freeze them for about 2 hours. Once frozen, transfer the banana slices to a freezer-safe container or bag for long-term storage.
No a banana cannot get frost
The banana will go black and be inedible
it takes 6 days or more for a banana to completely rot.
depends how cold and what you use to freeze it
If you dip them into liquid nitrogen (LIN) they will freeze instantly.
