P073 L’obésité diminue, de manière réversible, la préférence pour les lipides alimentaires chez la souris
2013
International audience; Introduction et but de l’étude. – Au cours des dernières années, il a été suggéré l’existence d’un lien étroit entre la détection oro-sensorielle des lipides alimentaire, la régulation de la prise alimentaire et l’IMC. Toutefois, les mécanismes affectant la sensibilité aux lipides ainsi que l’éventuelle implication directe de l’obésité restent mal connus.
Sensory exploration of the freshness sensation in plain yoghurts and yoghurt-like products
2013
WOS: 000324008600021 ; http://www.sciencedirect.com/science/article/pii/S0950329313001092; International audience; The term "freshness sensation" is used by consumers for characterizing some plain yoghurts and yoghurt-like products. This study consisted in an investigation of this sensation aiming at determining its underlying sensory attributes. First, two focus groups of consumers were conducted to open up the framework. A set of plain yoghurts and yoghurt-like products, both commercial and experimental, was then subjected to sensory analysis. The samples were sorted by means of a free sorting task, and further scored for the intensity of their freshness sensation and their liking, by 72 …
P059 Le lipido-récepteur intestinal CD36 et sa cascade de signalisation ERK1/2 dépendante contrôle la synthèse des chylomicrons
2013
International audience; Introduction et but de l’étude. – L’intestin est capable d’adapter sa capacité d’absorption à la teneur en lipide du régime. Cette adaptation implique un système de détection des lipides au niveau entérocytaire. Le CD36, qui est une glycoprotéine transmembranaire liant avec une forte affinité les acides gras à longue chaîne (AGLC), pourrait jouer ce rôle. En effet, ex vivo, la présence d’AGLC est associée à une activation de la voie ERK1/2 et conduit à l’induction de protéines clés du métabolisme intestinal des lipides : l’ApoB48 et la MTP. Cette régulation est CD36 dépendante (Tran et al. 2011). De plus, la déficience de CD36 est associée chez l’Homme et l’animal à …

On the consistency of liking scores: a validation study run in France and Germany
2005
International audience; A validation study was performed to confirm the findings of a previous experiment, by enlarging it at younger age groups. The study was conducted in France and Germany. Monadic preferences for seven orange juices were recorded. Three of the samples were replicates of the same juice (RJ). The four others were RJ slightly spiked with chemicals. Each subject then performed a paired preference test composed of RJ and the modified juice whose score was the furthest from the RJ score. Finally, subjects had to choose one among eight reasons why they preferred that sample. The effects of age, gender and country on the consistency of liking scores were examined. Most of the f…
Quelle information accompagne la distribution des Compléments Nutritionnels Oraux (CNO) à l’hôpital : un état des lieux
2019
Introduction et but de l’etude Bien que l’efficacite des Complements Nutritionnels Oraux (CNO) ait ete prouvee dans de nombreuses situations cliniques, leur utilisation en milieu hospitalier se heurte a des problematiques de prescription, de distribution et d’observance. L’objectif de l’etude etait de faire un etat des lieux des informations donnees par le personnel soignant aux patients lors de la distribution des CNO et d’etudier les representations des patients vis-a-vis de ces produits. Materiel et methodes Au cours d’une premiere phase, un observateur neutre a suivi les equipes de service et consigne tous les echanges verbaux entre soignant et patient lors de la distribution des CNO. A…
How the country-of-origin impacts wine traders’ mental representation about wines: A study in a world wine trade fair
2020
Using data collected at a world wine trade fair, we study how the country-of-origin impacts wine traders’ mental representation about wines. In the analysis we use traditional exporters in Old (France) and New (Argentina) world wine countries in comparison to non-traditional exporters in Old (Switzerland) and New (Brazil) world wine countries. Three main findings are reported. First, the country-of-origin of wines was more important on guiding participants’ representations, than the category of countries the traders came from. Second, participants’ evocations were more precise and specific for traditional wine-exporting countries than for less traditional wine exporting countries. Finally, …
Intestinal CD36. A lipid-sensor involved in the processing of chylomicrons in rodents
2011
International audience; CD36 is a multifunctional glycoprotein which binds nanomolar concentrations of long-chain fatty acids (LCFA) and is highly expressed on the luminal surface of enterocytes. Despite of its implication in oleoylethanolamide (OEA) and chylomicron synthesis, CD36 function in small intestine remains incompletely understood. Our in vivo data demonstrated that CD36 gene deletion in mice did not affect intestinal LCFA uptake. CD36 protein disappeared early from the luminal side of intestinal villi during the post-prandial period but only when the diet contained lipids. This drop was significant 1 h after a lipid supply and was associated with ubiquitination of CD36. Using CHO…
Sensory methodologies and the taste of water
2009
/WOS: 000285178000010; International audience; Describing the taste of water is a challenge since drinking water is supposed to have almost no taste. In this study, different classical sensory methodologies have been applied in order to assess sensory characteristics of water and have been compared: sensory profiling, Temporal Dominance of Sensations and free sorting task. These methodologies present drawbacks: sensory profile and TDS do not provide an effective discrimination of the taste of water and the free sorting task is efficient but does not enable data aggregation. A new methodology based on comparison with a set of references and named “Polarized Sensory Positioning” (PSP) has bee…
