Can Myrtenol be labeled natural?
The process decides for myrtenol. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic myrtenol 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.
- United States
- Natural or artificial, by process
- European Union and UK
- Natural only from natural material
- Mercosur and Mexico
- Natural or identical-to-natural
How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.
