Can trans-2-Octen-1-yl butanoate be labeled natural?
Nature makes trans-2-Octen-1-yl butanoate, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial trans-2-Octen-1-yl butanoate, same molecule. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
