Sodas: What is "Natural Flavor"?

[rahikumar]

I bought an off-brand carbonated peach soda. I wasn't expecting much, and it didn't taste like much. Then, the small print on the front caught my eye "peach and grapefruit natural flavor". This got me wondering. If the ingredients contain no natural juice(s), then where does "natural flavor" come from? Thin air?

I'm hoping the SDopers may know how one captures "natural flavor" without a conduit, such as the juice of the fruit? For one, is there a peach zest, I WAG?
