Goût, préférences et comportement alimentaire

2016

La population âgée se caractérise par une grande variabilité, que ce soit au niveau de la capacité à percevoir les saveurs et les arômes, des préférences alimentaires ou des attitudes vis-à-vis de l’alimentation. Cependant, nous avons montré que 88% des seniors jugeaient important d’avoir des aliments « savoureux, ayant un bon goût ». Nous avons également montré qu’améliorer la qualité sensorielle des aliments en fonction des recommandations des seniors eux-mêmes permettait d’augmenter les quantités consommées. Face à l’enjeu que représente la dénutrition chez les seniors, la recherche, les services de restauration et les industries agro-alimentaires se doivent de développer une offre alime…

Role of saliva in oral food perception

2014

Saliva is the first fluid that comes into contact with food during oral processing. Because saliva is the medium that bathes the taste receptors, is the fluid through which taste and aroma compounds are released into the oral cavity and is mixed continuously with food during bolus formation, it is an essential actor in oral chemosensory perception. The complexity of saliva composition, with compounds originating from different salivary glands, from gingival crevicular fluid, from micro-organisms and from food debris, together with its variable nature increases the possibilities for interactions with food compounds and for different roles in perception. These factors are increasingly being t…

Evolution de la perception sensorielle et des préférences alimentaires chez les personnes âgées : quel lien avec le statut nutritionnel ?

2012

Le processus de vieillissement, même lorsqu’il se déroule normalement, est associé à de nombreuses modifications d’ordre physiologiques (ralentissement du transit intestinal, du métabolisme basal, perte de dents, altérations des capacités chimiosensorielles), psychologiques (solitude, dépression, démence) et sociologiques (retraite, veuvage, déménagement…) susceptibles d’avoir un impact sur la prise alimentaire et le statut nutritionnel de la personne âgée. Au-delà de ces changements, l’apparition d’une dépendance pour l’alimentation, qui fait généralement suite à une perte d’autonomie de la personne (apparition d’une incapacité physique ou psychique, veuvage…), modifie en profondeur le rap…

Perception des molécules chimiosensorielles en mélange : impact du métabolisme périphérique

2015

The chemosensory system is highly sensitive and discriminant. To ensure these properties, rapid and effective mechanisms are necessary to eliminate chemosensory molecules reaching the perception interface. The xenobiotic metabolizing enzymes (XMEs) present in the peri-receptor space may participate to the clearance of molecules thus limiting chemosensory receptors saturation and promoting the termination of the signal. In our PhD thesis, the involvement of these enzymes in the detection of stimuli in mixture was assessed in two animal models allowing to test complementary aspects. In Drosophila melanogaster, a sensory exposure to caffeine causes a reversible alteration of the taste percepti…

The effectiveness of personalized design to feed elderly people

2015

Beyond the physiological age, the elderly population is characterized by a high heterogeneity in terms of physical, psychological and sociological status (Maître et al, 2015). Regarding eating behavior, several studies have highlighted a large inter-individual variability in chemosensory abilities (i.e. the ability to perceive an odor or a taste; Sulmont-Rossé et al, 2015) and oral-heath status (i.e. dental status, salivary flow; ALIMASSENS project), as well as inter-individual variability in food preference and food intake (AUPALESENS project). However, the food offer dedicated to the elderly population, and in particular to elderly people who needs help to obtain and/or prepare food for t…
