Perception sensorielle de la texture de gels en France et au Vietnam et prédiction des profils sensoriels par des mesures instrumentales

Abstract : The first objective of this thesis was to qualify and quantify the differences in the sensory characterisation of visual appearance and texture of gels between subjects of two very different cultures (French and Vietnamese). Three sensory methodologies with different verbalisation levels were used (free sorting task, flash profile and conventional profile) and made it possible to identify specificicities in the response pattern in the two cultures. Globally, the three methods also revealed a high level of similarity between products configurations in the two cultures. The second objective was to translate and transfer the sensory attributes of the two conventional panels in France and Vietnam towards two new panels respectively in Vietnam and in France. A protocol for attribute transfer between cultures was definied. Applying this protocol both in the way FRANCE-->VIETNAM and VIETNAM -->FRANCE made it possible to transfer attributes very efficiently between cultures. The third objective was to predict the sensory profiles of the panels who generated their own attributes in France and in Vietnam, by various instrumental measurements. A satisfactory level of prediction of sensory profiles by instrumental measurements was reached by using one syneresis variable, two photometer variables, four penetration variables and four back extrusion variables.
