Can alpha-Terpinyl acetate be labeled natural?

The process decides for alpha-Terpinyl acetate. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic alpha-Terpinyl acetate is artificial. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic alpha-Terpinyl acetate identical-to-natural.

Natural or artificial, by process
European Union and UK

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 TERPINYL ACETATE under CAS 80-26-2 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.
