In Vivo Aroma Release of Milk Gels of Different Hardnesses: Inter-individual Differences and Their Consequences on Aroma Perception
Résumé
The effect of textural modifications of solid milk gels on in vivo aroma release and aroma perception
was investigated with a panel of 14 subjects. Great inter-individual differences were observed on
aroma-release data, and the consequences of these differences on aroma perception were studied.
From a hierarchical cluster analysis performed with several parameters extracted from release curves,
the subjects were gathered into two groups, and a specific aroma-release profile was identified for
each one. Then, by using a sensory profile, we showed that the intensity of the aroma perception
was dependent on the release profile presented by the panelist. Second, we observed that, during
the chewing phase, the aroma was perceived as more intense for the firmer gel and for panelists for
whom the aroma release begins during the chewing of the product.
