Flavor: from food to behaviors, wellbeing and health

Revue; Andrée Voilley and Patrick Etiévant published a book entitled “Flavour in Food” in 2006. Since then, few progress was made in the field of flavor and taste constituents and of their interactions in various food matrices during the production process, the storage or the maturation of food and finally during eating.When our Publisher asked us an update for this edition, we thought that it was not the best thing to do, but that we should take advantage of this offer to publish a sort of follow-up of this first edition.In the last 10 years, it was obvious that large research efforts were made to understand how odor components stimulate the numerous receptors discovered in the early 1990s…

Wine bouquet: the perceptual integration of chemical complexity

Although hundreds of chemical compounds have been identified in grapes and wine, it has been repeatedly demonstrated that only a small fraction of these compounds in reality contribute to the flavor of wine. These compounds have the ability to activate at least one of the chemical senses located in the mouth and in the nose. Even if the actual number of flavor compounds is reduced, when compared to wine chemical complexity, the mixture of stimuli is transformed into a mixture of sensory signals that is integrated all along the sensory pathways to give rise to the wine’s bouquet. During this integration process, perceptual interactions, within and between senses, are likely to occur [1]. Bei…

Perceptual odor blending is influenced by chemical complexity of odorant mixtures

International audience; Perfumers and flavorists are familiar with odor blending phenomenon and often report that a minimum number of odorants has to be mixed for a good odor blend to arise. Previous studies in humans and animals suggested that a configural process could be involved in the perceptual analysis of mixtures of odorants. It has been proposed that the perceptual blending phenomenon corresponds to a configural perception of odorant mixtures. In the present study, we investigated the influence of chemical complexity on the configural perception of odorant mixtures. Six mixtures including 2 to 6 odorants as well as each unmixed odorant were assessed for their odor quality by a pane…

Les comportements alimentaires. Choix des consommateurs et politiques nutritionnelles

Ouvrage édité d'après l’expertise scientifique collective réalisée par l’INRA à la demande du ministère de l’Alimentation, de l’Agriculture et de la Pêche en 2009.; National audience; Quels rôles jouent, par exemple, la sensation de faim, la composition des aliments, les normes sociales, l’éducation, le revenu, la publicité... dans le comportement des consommateurs ? Quels seraient les leviers d’action publique à utiliser pour que ces consommateurs adoptent les recommandations nutritionnelles favorables à leur maintien en bonne santé ? Cette expertise scientifique collective met à disposition des décideurs et du grand public les connaissances acquises sur ces questions dans des champs disci…
