Can 2-Methyl-3(2-furyl)acrolein be labeled natural?

2-Methyl-3(2-furyl)acrolein occurs in nature, so the label depends on the route: 2-Methyl-3(2-furyl)acrolein won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized 2-Methyl-3(2-furyl)acrolein is artificial. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.
