Chemical Investigation and Authenticity of Indian Vanilla Beans

摘要

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.
