An exploratory study to investigate emotion elicited by immersive ambiances
2011
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…
The impact of chocolate on cardiovascular health
2011
Cardiovascular disease is the leading determinant of mortality and morbidity in women. Functional foods are attracting interest as potential regulators of the susceptibility to disease. Supported by epidemiological evidence, chocolate has emerged as a possible modulator of cardiovascular risk. Chocolate, or cocoa as the natural source, contains flavanols, a subclass of flavonoids. The latter years have witnessed an increasing number of experimental and clinical studies that suggest a protective effect of chocolate against atherogenesis. Oxidative stress, inflammation, and endothelial function define three biological mechanisms that have shown sensitivity to chocolate. Moreover, the consumpt…
Nose-space of dark chocolates using PTR-ToF-MS and link to flavour perception through simultaneous Temporal Dominance of Sensations (TDS)
2018
International audience; Introduction: Aroma of dark chocolate depends on process and cocoa origin and variety. A sensory analysis of 206 standardized chocolates produced from various cocoa beans classified them in four sensory categories. These categories were confirmed in a PTR-MS analysis of the chocolates volatilome [1]. The objective here was to study the nosespace of a subset of chocolates simultaneously with their temporal profile to better explain the sensory categorization at a perception level. Methods: A Temporal Dominance of Sensations (TDS) evaluation of 8 chocolates (2 selected per category) was done in triplicate by 12 subjects while the aroma released in their nose were simul…
