Dark chocolates organoleptic differences: a PTR-ToF-MS success story
2019
International audience; Aroma of dark chocolate depends on process and cocoa origin and variety. Repeated sensory analyses of standardized chocolates produced from various cocoa beans batches using a standard fabrication process allowed classifying them into four sensory categories. These categories were confirmed in a PTR-ToF-MS analysis of the volatilome of 206 chocolate samples through supervised multivariate data analyses (PLS-DA). Variable selection using dedicated methods pinpointed some volatile compounds important for the discrimination of the chocolates. Moreover, the nosespace of a subset of chocolates was measured by twelve assessors using PTR-ToF-MS with simultaneous determinati…

International audience; Aroma of dark chocolate depends on process and cocoa origin and variety. Repeated sensory analyses of standardized chocolates produced from various cocoa beans using a standard fabrication process allowed classifying them in four sensory categories. These categories were confirmed in a PTR-MS analysis of the volatilome of 206 chocolate samples [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. A Temporal Dominance of Sensations (TDS) evaluation of 8 chocolates (2 selected per category) was done in triplicate by 12 subjects while the…

International audience; Perception of flavor is a dynamic process during which the concentration of aroma molecules at the olfactory epithelium varies with time as they are released progressively from the food in the mouth during consumption. However, how the various components combine to produce a sensory impression is still not completely understood. Real-time mass spectrometry (MS) techniques that measure aroma compounds directly in the nose (nosespace) aim at obtaining data patterns that are supposed to reflect the way aromas are released in real time during food consumption. These patterns are supposed to be representative of the retronasal stimuli perception. Real-time sensory methods…
