Can 1-Ethyl-2-pyrrolecarboxaldehyde be labeled natural?
Nature makes 1-Ethyl-2-pyrrolecarboxaldehyde, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial 1-Ethyl-2-pyrrolecarboxaldehyde, same molecule. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic 1-Ethyl-2-pyrrolecarboxaldehyde 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 1-ETHYL-2-PYRROLECARBOXALDEHYDE under CAS 2167-14-8 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.
