Can Tetrahydrolinalool be labeled natural?

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

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 TETRAHYDROLINALOOL under CAS 78-69-3 and carries its FEMA number, its JECFA flavor number and its 21 CFR citations. 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.
