Can Furfuryl methyl ether be labeled natural?

The process decides for furfuryl methyl ether. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic furfuryl methyl ether is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
