Can trans-3-Nonen-1-ol be labeled natural?
Nature makes trans-3-Nonen-1-ol, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial trans-3-Nonen-1-ol, same molecule. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic trans-3-Nonen-1-ol identical-to-natural.
- United States
- Natural or artificial, by process
- European Union and UK
- Natural only from natural material
- Mercosur and Mexico
- Natural or identical-to-natural

United States
trans-3-Nonen-1-ol is FEMA GRAS under FEMA number 4605. It is cited in the Code of Federal Regulations at 21 CFR 172.515.
European Union and United Kingdom
No EU FL number is on file for trans-3-Nonen-1-ol. That is not a finding either way. The Union List covers defined flavouring substances, so natural complex materials are handled as flavouring preparations under Parts B to F and never receive a number, and substances used as additives sit under Regulation 1333/2008 instead. Confirm the position before EU or UK use.
