Can cis-2-Octenol be labeled natural?
The process decides for cis-2-Octenol. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic cis-2-Octenol 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.

- Natural or artificial, by process
- European Union and UK

Confirm the position before EU or UK use.
