What difference does this make? Are you suggesting the response would be different if she were or were not black? The point is that the officemate is doing something annoying, obnoxious and rude and how the OP should deal with it.
I know you want to avoid confrontation, but you should just speak up politely and say "I'm sorry, but I'm having problems concentrating. Can you please chew your gum quietly?"
