Abstract
The genuineness of vanilla is discussed by integral authenticity evaluation of vanillin and some characteristic minor compounds such as 4-hydroxybenzyl alcohol, vanillic acid, 4-hydroxybenzaldehyde, anisic alcohol, anisic acid, and 4-hydroxybenzoic acid, including isotopic data as well as gas chromatographic quantification of compounds analyzed. Such integral authenticity profiles are new and promising perspectives in the authenticity evaluation of genuine vanilla. Data-banks with two parameter series (isotopic data and quantification using internal standards) are suggested to be realized by interlaboratory ring tests. Keywords: Genuine vanilla; authenticity assessment; authenticitiy profiles; isotope analysis; multicomponent cGC-IRMS analysis
