Application of chromatographic methods to the determination of cognac quality indicators

Abstract

Gas and liquid chromatography methods were used to study 11 cognac samples; the analytical data were compared with the organoleptic control of the samples. The presence of triacetin and glycerol, an increased concentration of vanillin, and a high sucrose content should be considered as criteria for the possible adulteration of production.
