SENSORY ANALYSIS COMPARISON OF EIGHT BISCUITS BY FRENCH AND PAKISTANI PANELS

Abstract

ABSTRACT A set of eight biscuits from France and Pakistan have been evaluated in these two countries from a descriptive and a hedonic point of view. Two panels of assessors have provided sensory profiles, separately but working in a similar manner. Two sets of consumers have provided hedonic scores. In order to compare these results, methods based on analysis of variance and multiple factor analysis have been defined. The comparison of the sensory profiles obtained in the two countries shows a convergence which argues in favor to say that it is not necessary to perform sensory profiling in every country where the products have to be sold. On the contrary, the comparison of hedonic scores showed not only the different trends in the two countries but also consumers from the two countries who like and dislike the same products. PRACTICAL APPLICATIONSThis work reinforces the idea according to which it is possible to carry out descriptive sensory evaluations by tasters not belonging to the market targeted. It illustrates some inherent difficulties with the collection of sensory evaluations carried out in different countries as well as a methodology for analyzing such data; in particular, we proposed grids of analyses, models of variance analysis, tables of syntheses and factorial methods adapted to this type of data. On the level of hedonic judgments, the dangers not to collect data from the targeted market are illustrated; moreover, we propose a methodology for analyzing hedonic judgments obtained from two populations.
