Can Pyruvaldehyde be labeled natural?

Nature makes pyruvaldehyde, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial pyruvaldehyde, same molecule. 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.
