Can 5-Methylfurfural be labeled natural?
Since 5-Methylfurfural is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when 5-Methylfurfural is synthesized. 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.
