Chemical references in sensory analysis of smoke flavourings

A new descriptive language and the corresponding set of chemical standard references for the evaluation of smoke flavourings is proposed. Analysis of variance (ANOVA) and linear discriminant analysis (LDA) were applied to validate this lexicon as well as to analyse reproducibility, discriminatory ability and homogeneity of the panel. Results confirmed that the developed methology was adequate to describe and discriminate commercial smoke flavourings. The number of low correlations demonstrates the need to maintain the majority of the descriptors for carrying out descriptive quantitative sensory analysis of smoke flavourings.
