PROGRESS IN THE AUTHENTICITY ASSESSMENT OF VANILLA .1. INITIATION OF AUTHENTICITY PROFILES

The genuineness of vanilla is discussed by integral authenticity evalu ation of vanillin and some characteristic minor compounds such as 4-hy droxybenzyl alcohol, vanillic acid, 4-hydroxybenzaldehyde, anisic alco hol, anisic acid, and 4-hydroxybenzoic acid, including isotopic data a s well as gas chromatographic quantification of compounds analyzed. Su ch integral authenticity profiles are new and promising perspectives i n the authenticity evaluation of genuine vanilla, Data-banks with two parameter series (isotopic data and quantification using internal stan dards) are suggested to be realized by interlaboratory ring tests.
