Can (E,Z)-3,6-Nonadien-1-ol be labeled natural?
(E,Z)-3,6-Nonadien-1-ol occurs in nature, so the label depends on the route: (E,Z)-3,6-Nonadien-1-ol won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized (E,Z)-3,6-Nonadien-1-ol is artificial. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic (E,Z)-3,6-Nonadien-1-ol identical-to-natural.
