What contributes to the change of color after cutting the banana?

When fresh fruits and vegetables are peeled or cut open, the enzyme called polyphenol oxidase (also called tyrosinase) contained in the cells is exposed to and reacts with the oxygen in the air. The reaction that occurs, which is called oxidation, is what turns the fruits and vegetables brown.

Why do banana peels get thinner as they ripen?

The skin of an unripe banana is full of water. Although the skin is quite watertight on the outside, water is gradually lost from the skin by osmosis to the fruit inside as the banana ripens. This causes the skin cells to wilt and collapse, making the overall skin thinner and more pliable.
