Intégrations perceptives dans la perception du goût

Characterisation of the volatile odorant fraction of aromatic caramel using heart cutting two-dimensional gas chromatography.

Poster (1 page); National audience; Odour is one of the main factors contributing to the consumer acceptability of food products. Characterization of odorant compounds thus represents an important challenge for the food industry. Caramel is the resulting product of controlled heat treatment of sugars. Its volatile fraction includes a large number of oxygenated heterocycles as furans and furanones. Due to similar properties, these compounds exhibit similar interactions with the column stationary phase. Consequently, the one-dimensional Gas Chromatography (GC) profile of the volatile fraction of caramel shows numerous co-elutions. The aim of this study was to optimize a two-dimensional chroma…

An exploratory study to investigate emotion elicited by immersive ambiances

Food behaviour is modulated by the eating situation and environment. In a previous study, we investigated drink choices according to the ambiance by developing an immersive approach based on the concept of “having a drink in a bar”. Two bars (Modern vs. Traditional ambiance) were settled with a few piece of furniture (counter, tables and bar stools) made in raw wood for the Traditional bar and in blue retro-lighted translucent plastic for the Modern bar. A video-clip was projected on one wall: Red moving shapes associated to a “far west” music in the Traditional bar, and Blue moving bubbles associated to an “electro” music in the Modern bar. In each bar, 100 participants were asked which be…
