Can 2,6-Dimethylpyridine be labeled natural?

2,6-Dimethylpyridine occurs in nature, so the label depends on the route: 2,6-Dimethylpyridine won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized 2,6-Dimethylpyridine is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.

Sources and attribution. The identity and regulatory facts on this page are taken from the FDA Substances Added to Food inventory, a US government record, which lists this substance as 2,6-DIMETHYLPYRIDINE under CAS 108-48-5 and carries its FEMA number, its JECFA flavor number. The inventory is searchable at FDA. FDA records its technical effect as flavoring agent or adjuvant.

A FEMA GRAS conclusion is reached by the Expert Panel of the Flavor and Extract Manufacturers Association of the United States, and the FEMA number names that conclusion. FEMA publishes its own entry for this substance in the FEMA Flavor Library, which is the authoritative record of what the Panel decided and is worth reading alongside this page.
