Relationships between sodium mobility, in-mouth salt and aroma release, and flavour perception : application to model cheeses
2012
The aim of this work is to understand the effects of changes in the composition of model cheeses on mobility, release and perception of flavor molecules (salt, aroma compounds). Six flavoured model cheeses were formulated (3 lipid/protein (L/P) ratios and 2 salt contents). The microstructure and the rheological properties of the model cheeses were characterized respectively by confocal microscopy and by uniaxial compression test. The mobility of sodium ions was analyzed by 23Na NMR. The kinetics of sodium release was followed in water and then in saliva during consumption of the model cheeses. The retronasal release of aroma compounds was followed by nose-space APCI-MS, simultaneously with …

De l'interventionnisme d'État à la libéralisation de l'école
2008
Cet article écrit pour le 40ème anniversaire des évènements de 1968 dans le monde, en Europe et en Suisse tente de montrer que ce qui s'est passé dans l'école n'est pas étranger à ce qui s'est passé dans les autres structures sociales : hôpitaux, usines . Ainsi l'évolution des modes de régulation qui s'installent dans les systèmes éducatifs n'est pas étrangère à l'évolution des modes de régulation installés dans les autres structures de l'Etat qui eux-mêmes ne sont pas étrangers aux modes de régulation dominants dans le monde. Après un bref rappel historique, quelques caractéristiques socio-politiques des revendications des années soixante sont rappelées, et sur cette base la situation de l…
Enzymatic cross-linking of pea proteins to produce microparticles : application to the encapsulation of riboflavin
2015
In this work, pea proteins behavior toward enzymatic gelation by microbial transglutaminase (MTGase) was studied at native state and after denaturation (chemical reduction or thermal denaturation). The final application was the formation of protein microparticules to encapsulate riboflavin, chosen as hydrophilic active molecule model. The extraction process of the pea protein fractions has been optimized in such a way to minimize as possible protein denaturation and recover native fractions rich in albumin (Alb) and globulin (Glob) or a mixture of both.The setting up of the enzymatic reaction monitoring methods has brought out their complementarity as well as their limits. Two new monitorin…
Enseigner la rhétorique à l’École de Bruxelles
2021
Cet article expose la conception de l’enseignement de la rhétorique à l’École de Bruxelles. Il explique l’origine de la démarche dans la pensée de Perelman. Il montre ensuite comment l’équipe du GRAL a retrouvé l’enseignement des exercices de rhétorique par les sophistes. Il propose une réflexion épistémologique pour montrer la spécificité de cet enseignement. Il termine enfin par l’exposé d’un exercice de délibération conçu et animé par les membres du GRAL. This paper outlines the conception of the teaching of rhetoric at the Brussels School. It explains the origin of the approach in the thought of Perelman. It then shows how the GRAL team recovered the teaching of rhetorical exercises by …
L'orientation politique des politiques d'orientation
2011
L'objectif poursuivi ici consiste à démasquer les lieux communs du néolibéralisme qui président aux décisions politiques relatives aux Services d'Information et d'Orientation (SIO) " au sens aristotélicien de notions ou de thèses avec lesquelles on argumente mais sur lesquelles on n'argumente pas". Pour tenter d'apporter quelques éléments de réponse cinq points sont successivement développés : - Le contexte idéologique et politique et l'individu entrepreneurial à orienter - L'impact de l'Union européenne
Study of relationships between the structure of aroma compounds and their retention-release between vapour phase and dairy gels
2010
An integrated approach physicochemistry and structures activity relationships has been carried out to study the aroma compounds retention-release phenomenon in a fat free dairy gel added with pectin. This study aimed to identify the molecular properties that govern this phenomenon assuming that modifying the structure leads automatically to a change in the retention-release of aroma compounds. For this purpose, we have determined the partition coefficients of 28 aroma compounds in water, in pectin gels and in dairy gels supplemented or not supplemented with pectin, at equilibrium conditions using the PRV method (Phase Ratio Variation). Then, we have performed a structure-retention relations…
Charles XIV Jean (alias Jean-Baptiste Bernadotte) and the Finnish Question
2008
One of the first important acts of Charles Jean XIV as head of Sweden was to renounce the idea of reconquering Finland. It was a difficult position to take, considering the conditions of the time, and in all likelihood, he swung back and forth for several months before taking a definitive decision, contrary to what he might have asserted later. Moreover, the regent, then sovereign, of Sweden, was forced to justify his choice throughout his reign and to navigate between the dangerous reefs of a diverse opposition , which was organised to varying degrees.Thus, the Finnish policy was, for another thirty years, a thorn in the side of the royal power at Stockholm.
