Can Myristaldehyde be labeled natural?
The process decides for myristaldehyde. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic myristaldehyde is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material 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.
