Can m-Dimethoxybenzene be labeled natural?
Nature makes m-Dimethoxybenzene, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial m-Dimethoxybenzene, same molecule. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic m-Dimethoxybenzene identical-to-natural.
- 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.
