Can Phenylacetaldehyde 2,3-butylene glycol acetal be labeled natural?
The process decides for phenylacetaldehyde 2,3-butylene glycol acetal. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic phenylacetaldehyde 2,3-butylene glycol acetal is artificial. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.
