Can Ethyl 3-(furfurylthio)propionate be labeled natural?
Since ethyl 3-(furfurylthio)propionate is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when ethyl 3-(furfurylthio)propionate is synthesized. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.

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