Chemical investigation and authenticity of Indian vanilla beans.
Representative and validated samples taken from a 500 acre vanilla (Vanilla planifolia Andrews) plantation in India have shown significant deviations in aromatic profile, especially the relative amounts of vanillin (high) and p-hydroxybenzaldehyde (low) and the deuterium isotopic (SNIF-NMR) values. However, the carbon isotopic values (carbon 13 profiles) were generally in accordance with the previous findings on vanilla from other geographic origins.
