Artificial and natural flavoring

There is something that puzzled me for a while; what is artificial chicken/meat flavor?

Artificial flavors can contain natural ingredients that underwent certain chemical treatment, or contain part natural, part lab-synthesised ingredients. Bottom line: artificial OR natural flavor can be almost anything.

This article is also great because it dicusses the use of "natural flavor" as a catch phrase; people tend to associate it with healthy food, while in most cases there is no difference, and sometimes artificial flavors can even be safer, and almost always - cheaper.

Also, in the first post I complained that there is no complete list of ingredients with descriptions; well, there is:

Next time instead of Googling frantically, can check that first.
