Can 4-Allylphenol be labeled natural?
The process decides for 4-Allylphenol. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic 4-Allylphenol is artificial. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.
