It's a natural wax (which is, of course, non-petroleum based) called carnauba wax. It's common to use wax in various foods including cheese and chocolate. Apples, for example, are not waxed for cosmetic reasons, but actually, the wax helps it keep firm and juicy, and protected from the penetration of bacteria. Basically, the carnauba is a replacement for the apple's own natural wax, which it produces on its own, but gets washed off when the farmers clean it. The carnauba wax is then applied to mimic the apple's own natural wax-- keeping the good stuff in, and the bad stuff out.
