LEOS Nov 25th: Temporal Dominance of Sensation

Nov 25th, Senate House Room G37 6.30-8.30pm

It is well known  that different attributes are perceived at different time of the tasting and it is assumed that this sequence of perception is relevant for the understanding of consumer preferences. Temporal Dominance of Sensations (TDS) is a relatively new technique which asks the panelists to pick repeatedly the attribute which dominates over the others. It is thus a descriptive technique in which the scoring of intensities has been replaced by the identification of dominant attributes allowing for temporality of sensations to be established.  TDS can therefore be used to measure the complexity of drinking experiences.  For this LEOS, Pascal Schilch will demonstrate a new TDS software using wine as a a key example.

Pascal Schlich is a Director of Research with the INRA (National Institute for Agronomical Research) in Dijon, France. He is currently the head of the ChemoSens platform which gathers the facilities in both sensory and physicochemical analyses of the Center for Taste and Feeding (CSGA) in Dijon. Dr. Schlich is a statistician by trade who specialized in sensometrics. He has been doing methodological research for about 25 years on difference testing, panellist performances, descriptive analysis, preference mapping and new sensory data collection techniques such as the Temporal Dominance of Sensations (TDS). These last 10 years he was in charge of national research projects about sensory education of children and consumer preferences towards fat, sweet and salt sensations. Dr Schlich also teaches statistics for sensory analysis at the University of Dijon and in several other universities and high schools in France.
