Can 2-Pentanol be labeled natural?
2-Pentanol occurs in nature, so the label depends on the route: 2-Pentanol won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized 2-Pentanol 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.
