Can Ethyl cinnamate be labeled natural?
Since ethyl cinnamate is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when ethyl cinnamate is synthesized. 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.
