I have noticed that putting bananas in the fridge has a weird effect, the peel turns black like if it's outside, but the inside of the banana stays yellow and hard. It is very weird to peel a full black banana and find the inside normal without any browning

I see this all the time with bananas that go from green to brown without turning yellow, I always heard people blame the bananas getting too cold during shipping.

I lost it when I moved but we used to have a chart on the fridge that said which fruits you should or should not store together because they make each other ripen faster.

Whenever I see this happen, I like to say the bananas are sublimating.

Bananas emit a gas that causes them to ripen faster. The same gas can also cause other fruits in the same space to ripen. It's weird but kinda useful. There are products out there claiming to absorb this gas, to keep everything fresh for longer.

Wild assed guess: the cold slows down the chemical reactions in the flesh of the banana but cannot save the skin. Putting bananas in a bag makes them ripen faster, and a fridge is just a larger enclosed space.

This! I used to think fridging bananas ruined them right away as they went brown, until I learned the insides are perfectly fine.
