Can 2-Ethyl-2-heptenal be labeled natural?
Since 2-Ethyl-2-heptenal is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when 2-Ethyl-2-heptenal is synthesized. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
