Question

why Banana peel darken after they are peeled but not before.

In: Biology

Answer 1

Peeling the banana breaks open a lot of the cells which cause it to brown faster. You can see this if you take a banana slice part of it into rounds while still in the peel the skin will only brown where you cut it and the rest is fine. Alternatively, you can take a banana and scratch a message or picture onto the skin with a pin. After about an hour your scratchings will turn brown and become visible.

Answer 2

Bananas constantly produce a molecule that basically tells itself to grow/get older

And if you let a banana sit around for 2 weeks it will definitely darken peeled or not

Answer 3

Have you really never seen a ripe banana unpeeled? Leave a banana out and check it out each day.
