Can Allyl heptanoate be labeled natural?
The process decides for allyl heptanoate. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic allyl heptanoate is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
