The Short Answer
Burning could also be called carbonising. I'm sure there's someone who can explain better than me, but burning food is the exact same as burning a lump of wood. Burning is a chemical reaction called combustion, and I can't remember any exact formulas but it uses oxygen, along with the organic compounds in the wood or food (generally composed of carbon, hydrogen and oxygen with some other fun things in there). One of the by products of the reaction is carbon dioxide which is just released into the air, and another is solid carbon, which is the black stuff left behind. Sorry if this answer is a bit long but basically; TLDR: it goes black because the combustion reaction uses up most of the other parts of the compounds in the food, and what's left is solid carbon which is black. Edit: as a few people have pointed out, it is incomplete combustion that produces solid carbon, which is the result of imperfect combustion conditions, for example not enough oxygen available for the reaction.
