Viscosity of artificial bolus of high protein extruded snacks
2018
Pulse legumes (pea, lentil, faba bean) are excellent source of proteins (20-30% db), dietary fibers (10-30%), and starch (40-55%). The formulation of gluten-free extruded snacks made entirely from pulse legumes is an interesting way to introduce legumes to young people. Due to the reactivity of protein components under thermomechanical treatment, extrusion can produce cellular structures with various texture and starch-protein composite morphology. In turn, the morphology of parietal material governs masticatory performances. For the first time, the interaction coefficient between bolus and saliva was determined by taking into account multi-scale structure of high-protein solid foams. The p…
Evaluation de la déstructuration orale de protéagineux extrudés
2018
La formulation de snacks expansés sans gluten et riches en protéines, fabriqués entièrement à partir deprotéagineux, est un moyen intéressant pour diversifier l’offre d’aliments à base de protéagineux.L'extrusion est un procédé souple et adapté pour fabriquer de tels aliments. Lors du traitementthermomécanique, la dépolymérisation de l’amidon, et donc sa solubilité, augmentent, alors que la solubilité des protéines diminue à cause des phénomènes d’agrégation. En conséquence, l'extrusion produit des mousses solides avec une grande variété de textures et de morphologies du matériel constitutif, autant de caractéristiques qui vont affecter les performances de mastication et l’acceptabilité du …
L25 Influence of mastication and salivation on salt release during bread consumption and relationships with food bolus formation

Aroma release and chewing activity during eating different model cheeses
2007
International audience; This study focused on the effect cheese properties had on chewing behaviour and aroma release as well as the relationship between them. Chewing activity and the kinetics of aroma release were simultaneously monitored during the consumption of eight model cheeses with the same flavour content. Differences in chewing behaviour explained most of the variability in aroma release among subjects. Aroma release increased with chewing work, bursts’ number and amplitude. For cheese samples, the chewing behaviour varied according to texture. Interaction between cheese composition and the chewing behaviour effects affected aroma release: (i) decreasing fat content increased aro…
In-mouth aroma compound release during cheese consumption: Relationship with food bolus formation
2011
International audience; The present study describes the changes in mechanical properties and saliva incorporation for cheese samples with different composition and texture, and their influence on the rate of aroma release. Chewing work per cycle, salivary flow rate and chewing rate varied highly among subjects. Despite the differences in cheese hardness, at the end of mastication, bolus texture was the same for cheeses with the same lipid content. Low-fat cheeses gave harder bolus than high fat ones, despite being chewed longer, with higher work per cycle and more moisture. Salivary flow rate did not vary among cheese samples but, at the end of mastication, the amount of saliva in boluses d…
Evaluation de l’effet de recommandations sur l’introduction de textures dans les premiers mois de diversification alimentaire sur les pratiques paren…
2021
National audience; Introduction et but de l’étude : Proposer des aliments texturés aux nourrissons rapidement après l’initiation de la diversification alimentaire est essentiel pour leur apprendre à bien mastiquer et développer un répertoire alimentaire sain. Le comité d’experts en nutrition de l’ESPGHAN recommande d’introduire les aliments texturés entre 8 et 10 mois au plus tard. Or, des travaux ont montré qu’en France, les purées restent privilégiées par de nombreux parents pendant la première année et que les enfants sont capables de manger des textures plus complexes d’après une étude comportementale. La question de la texture n’étant pas abordée en détail dans les recommandations de s…
Vous mangez trop salé !
2016
Revue non indexée dans JCR.; La consommation de sel est excessive dans les pays industrialisés. Les autorités sanitaires recommandent donc une réduction drastique de la quantité de sel incorporée dans les aliments manufacturés. Afin de conserver une perception du produit à teneur réduite en sel identique à celle du produit original, le rendement d’extraction du sel par la salive doit donc être amélioré, par exemple en modifiant la texture de l’aliment. Le sel se libère graduellement des aliments solides pendant les processus résultant de la mastication et de la salivation et entraînant la déstructuration de l’aliment. Deux sondes ont été développées pour la mesure de la température et de la…
Satisfaction of patients fitted with implant-retained overdentures
2011
Objective: to evaluate patient satisfaction with implant-retained overdentures, and its relationship with age, sex, period of follow-up, the rehabilitated jaw (maxilla, mandible or both), number of implants, splinting, type of attachment and the antagonist.Material and methods: the study comprised patients with overdentures fitted between January 1996 and June 2007, and with a minimum follow-up of one year. Data regarding patients and prostheses were collected. The patients indicated their overall satisfaction on a visual analogue scale (VAS) from 0 to 10, as well as satisfaction for individual items such as aesthetics, speech, mastication, prosthetic stability and selfesteem. These data we…
