Utilisation de la Dominance temporelle des sensations pour la caractérisation sensorielle des produits de la filière blé-farine-pain
2012
Eurogerm is specialized in flour correctors, bread improvers and technological ingredients for the wheat, flour and bread sector. The company gives great importance to sensory analysis as a diagnostic tool of finished products and has four expert panels; each panel is specialized in one category of products and is trained to standard sensory profiling. Today, in addition to the traditional method, Eurogerm wants to explore new methods in order to offer new services to its customers. This paper describes the development of Temporal Dominance of Sensations (TDS) created in the “Centre des Sciences du Goût et de l’Alimentation” (CSGA) (PINEAU et al., 2009). TDS provides information on the perc…

Estimating finite mixtures of semi-Markov chains: an application to the segmentation of temporal sensory data
2019
Summary In food science, it is of great interest to obtain information about the temporal perception of aliments to create new products, to modify existing products or more generally to understand the mechanisms of perception. Temporal dominance of sensations is a technique to measure temporal perception which consists in choosing sequentially attributes describing a food product over tasting. This work introduces new statistical models based on finite mixtures of semi-Markov chains to describe data collected with the temporal dominance of sensations protocol, allowing different temporal perceptions for a same product within a population. The identifiability of the parameters of such mixtur…
