Can 1-Methyl-1H-pyrrole-2-carboxaldehyde be labeled natural?
1-Methyl-1H-pyrrole-2-carboxaldehyde occurs in nature, so the label depends on the route: 1-Methyl-1H-pyrrole-2-carboxaldehyde won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized 1-Methyl-1H-pyrrole-2-carboxaldehyde is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
