T@sty(TM) : test d'évaluation de la sensibilité aux saveurs. Dispositif breveté pour l'évaluation de la sensibilité de sujets pour les 5 saveurs
2019
T@sty est un dispositif permettant d'évaluer la sensibilité de sujets humains pour les cinq saveurs (sucrée, salée, amère, acide et savoureux). Cette évaluation peut-être réalisée à domicile (tests envoyés par la poste, questionnaire de réponse en ligne). Pour chaque saveur, un kit d'évaluation est constitué de 3 feuilles-tests entièrement comestibles. Chaque feuille-test comporte 6 séries de 3 disques détachables. Pour chacune des séries, les participants doivent goûter les trois disques par simple contact avec la langue, puis identifier le disque qui porte une saveur (les deux autres sont neutres). L'intensité de la saveur est croissante (série 1 à 6). Avantages Aucune préparation pour l’…

Deux approches sensorielles autour du concept gras/volume dans les vins blancs et les vins rouges
2013
Introduction. Les descripteurs gras et volume sont des mots très présents dans le discours spécialisé des professionnels du vin mais il ne va pas de soi, a priori, que les différents locuteurs se comprennent quand ils utilisent l’un et l’autre de ces deux termes. Le processus cognitif de détermination sensorielle de ces deux descripteurs apparaît complexe car à la fois multimodal et multiparamétrique. La viscosité, la texture ou le caractère tapissant sont, parmi bien d’autres, autant de dimensions potentiellement sous-jacentes à ces deux termes (Folkenberg et al., 1999 ; Szczesniak, 2002). De plus, et comme le soulignaient déjà Guinard et Mazzucchelli en 1996, le processus de détermination…
Bresaola made from Cinisara cattle: effect of muscle type and animal category on physicochemical and sensory traits
2020
The physicochemical characteristics and sensory traits of Cinisara bresaola were investigated, to explore a new commercial opportunity for autochthonous dairy cattle farms. Semimembranosus, Semitendinosus and Biceps brachii muscles, from adult cows (AC) and grazing (GB) or housed (HB) young bulls of Cinisara breed, were processed to made bresaola. Differences due to animal category and muscle type were observed. Bresaola from AC was richer in fat and volatile organic compounds. The bresaola from Semitendinosus showed higher colorimetric parameters, fat and, when from grazing animals, Warner-Bratzler shear force than those made from other muscles. In general, all bresaola were well appreciat…
Impact of information and in-home sensory exposure on liking and willingness to pay: The beginning of Fairtrade labeled coffee in France.
2015
This study was conducted to assess how the Fairtrade label interacts with the perception of intrinsic product characteristics on liking and purchase decisions and to estimate the evolution of this interaction after exposure to the coffees and/or exposure to ethical information. In a first session, 119 consumers gave liking scores for 2 regular and 2 Fairtrade coffees under a blind tasting condition. Then, they were asked to indicate the maximum price they would pay for each product in 2 auctions taking place under different information conditions. In the first auction, participants saw the packaging but did not taste the coffee; in the second auction, they could both taste the coffee and se…
De la perception sensorielle à la consommation du vin. Partie 1/2 : Mécanisme de la perception sensorielle : reflet de la réalité
2010
National audience; Afin de percevoir son environnement et de pouvoir réagir en conséquence, l’être humain est équipé de capteurs sensoriels. Ces capteurs constituent une interface entre le sujet et le monde extérieur et quelle que soit la stimulation extérieure, ils mettent en jeu les mêmes mécanismes sensoriels. Lorsque les capteurs sensoriels rentrent en contact avec un stimulus, les informations engendrées sont amplifiées, puis transmises au système nerveux central sous forme de signaux électriques (Mac Leod et Sauvageot, 1986) après avoir été progressivement filtrées, réduites et stabilisées. Ces informations électriques sont caractérisées d’une part par une masse globale d’activité, co…
Spectral calibration of hyperspectral imagery using atmospheric absorption features
2006
One of the initial steps in the preprocessing of remote sensing data is the atmospheric correction of the at-sensor radiance images, i.e., radiances recorded at the sensor aperture. Apart from the accuracy in the estimation of the concentrations of the main atmospheric species, the retrieved surface reflectance is also influenced by the spectral calibration of the sensor, especially in those wavelengths mostly affected by gaseous absorptions. In particular, errors in the surface reflectance appear when a systematic shift in the nominal channel positions occurs. A method to assess the spectral calibration of hyperspectral imaging spectrometers from the acquired imagery is presented in this p…
Changes in surface stress, morphology and chemical composition of silica and silicon nitride surfaces during the etching by gaseous HF acid
2007
International audience; HF acid attack of SiO2 and Si3N4 substrates is analyzed to improve the sensitivity of a sensor based on inicrocantilever. Ex situ analysis of the etching using XPS, SIMS and AFM show significant changes in the anisotropy and the rate of the etching of the oxides on SiO2 and Si3N4 surface. Those differences influence the kinetic evolution of the plastic bending deflection of the cantilever coated with SiO2 and Si3N4 layer, respectively. The linear dependence between the HF concentration and the Si3N4 cantilever bending corresponds to a deep attack of the layer whereas the nonlinear behavior observed for SiO2 layer can be explained by a combination of deep and lateral …
Quality, Reliability, Security and Robustness in Heterogeneous Systems
2020
This book constitutes the refereed post-conference proceedings of the 15th EAI International Conference on Quality, Reliability, Security and Robustness in Heterogeneous Networks, QShine 2019, held in Shenzhen, China, in November 2019. The 16 revised full papers were carefully reviewed and selected from 55 submissions. The papers are organized thematically in tracks, starting with mobile systems, cloud resource management and scheduling, machine learning, telecommunication systems, and network management.
Ultrasound accelerated esterification of bile acids
2004
In this study power ultrasound accelerated esterification reactions of some model substances and bile acids were done. In the model reactions the best result was 19-fold increase in the reaction rate when using ultrasound and the temperature was allowed to rise during the irradiation. In the case of bile acid methyl esters a clear increase in the reaction rates was also observed by ultrasonic irradiations.
