Les stratégies payantes pour doper la perception sucrée en bouche
2018
La réduction du sucre s'accélère en 2018. Zoom sur les dernières avancées de la recherche dédiée aux récepteurs gustatifs. Les aromaticiens focalisent leurs recherches sur la mise au point d'arômes modulateurs qui équilibrent le profile aromatique des produits allégés.

Détection orosensorielle des lipides alimentaires chez la souris : mécanismes impliqués et altérations au cours de l'obésité
2015
Dietary lipids are detected by the gustatory system in rodents and humans. Two candidate lipid-receptors are found in taste buds: CD36, which is involved in the fat taste as shown by studies conducted in our laboratory, and GPR120. Our results show that GPR120 is not directly involved in the gustatory detection of lipids in mice, but could rather be involved in the modulation of the sensitivity for fat. When this gustatory system works properly, food choices can meet the organism’s energy needs. Besides, the pleasure brought by the consumption of palatable foods is satisfied. However, obese people often overconsume energy-dense food. In the central nervous system, perturbations of the rewar…
Chlorine flavor perception and neutralization in drinking water
2010
For water suppliers, using chlorine is necessary to ensure water bacteriological quality from the treatment plant to the consumers’ tap. However, chlorine flavour is one of the most common reasons advocated for choosing tap water alternatives as drinking water. As a consequence, the putative link between chlorine flavour perception and tap water consumption is an issue in drinking water habits studies. Since the sensory mechanisms involved in chlorine flavour perception remained largely unknown, the main objective of this thesis work was to first highlight those mechanisms and then to identify potential lever chlorine flavour sensory neutralisation.In a first step, we demonstrated that hypo…

Hedonic sensations implicated in the control of human food intake : alimentary alliesthesia and sensory-specific satiety
2011
The control of food intake is a complex and multifactorial process controlled by the CNS. It is implicated in the regulation of body weight and the supply of energy substrates, as well as the supply of a panoply of nutrients to cover the specific needs of the organism. Among all the factors involved, hedonic sensations play an important role in guiding food selection and limitation of intake. The theoretical section of this thesis takes into account the physio-anatomical aspects of the control of food intake, in particular sensory pleasure and its evaluation, within the framework of the three principal hedonic phenomena: Conditioned Satiety (CS), Alimentary alliesthesia (AA) and sensory-spe…

La brazzéine, une protéine au goût sucré et aux propriétés hors normes
2018
Danss une démarche globale de réduction des sucres dans les produits alimentaires, les protéines au goût sucré sont une alternative encore peu répandue mais à fort potentiel. La brazéine, notamment, possède des propriétés très intéressantes pour l'industrie agroalimentaire. Quelles sont ces propriétés ? Comment peut-on la produire à échelle industrielle ? Quels sont les avantages et les inconvénients de cette protéine ?
