browning is due to oxygen, O2, reacting with chemicals released, breaking down the cells in the fruit. The reaction is called enzymatic oxidation as it is a process catalysed by the enzymes present in the apples

Why does a sliced apple colour change when sliced?
The air has carbon dioxide in it, & it turns the apple if it's left out too long. I think it is the oxygen in the air that oxidizes the apple. The oxidation reaction basically forms a sort of rust on the surface of the fruit. You see the browning when the fruit is cut or bruised because these actions damage the cells in the fruit, allowing oxygen in the air to react with enzymes and other chemicals.
