Can Zingerone be labeled natural?

Zingerone occurs in nature, so the label depends on the route: zingerone won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized zingerone 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.
