      Hi, this is actually quite far away from the stuff I know about. I think that you should ask Gaia this, and let me know the answer! It’s a good quesiton

    On the inside of apples (and pears, potatoes etc) are things called enzymes. Enzymes increase the speed that chemical and biological things happen. When exposed to oxygen, these enzymes ‘oxidise’. That’s exactly the same thing that happens to Iron when it gets wet, making rust. So apples are effectively rusting! As you know, rust is brown 😎
