Influence of the composition and the structure of different media on the release of aroma compounds

2004

International audience; The release of 2-nonanone and hexenol (hex-4-en-3-ol) was studied in model media with different structures and compositions: water, a gel of $\beta$-lactoglobulin, gelified or non-gelified emulsions (5.0% Miglyol, 6.9% $\beta$-lactoglobulin; the gelation was realized by heating) and milk. The aroma compounds were analyzed by gas chromatography. A strong influence of the nature of the volatile compound on its behavior towards the food matrix was observed: in the case of 2-nonanone, a hydrophobic compound (log P = 2.9) with a relatively high vapor-water partition coefficient (Kmol = 33.6), the release was greatly influenced by the composition and the structure of the m…

Influence of solvent-free reticulation treatment on edible film properties based on chitosan and gelatin, containing or not natural antioxidants : ph…

2015

This thesis aims to develop an edible packaging made of a mixture of chitosan and gelatin (beef or fish), to better understand the influence of the electron beam irradiation and of the incorporation of natural antioxidants on the physico-chemical and functional properties of the films. A study of the effect of irradiation on antioxidants release kinetics in a simple liquid medium was studied for validation. A preliminary study first showed that the densification of the film-forming solution and the gel during drying does not depend on the thickness or concentration or time and suggests a Fickian diffusion of water in the matrix. The permeability to water vapor increases linearly with film t…

Libération du sodium et des composés d'arôme dans des modèles fromagers aromatisés : influence de la structure et de la composition

2010

Authorities have called for salt content to be reduced in various food products. Cheese appears to be one of the most targeted products. In order to understand how to reduce salt content in model cheeses without modifying salty perception, the interactions between in-mouth sodium release and cheese composition and structure have to be studied. . The current study was conducted to determine how the release of aroma compounds and sodium ions could be modified by the structure and the composition of model cheese (lipid/protein ratio, sodium content ...). This will be done by in vivo and in vitro approaches. 23Na Nuclear Magnetic Resonance (NMR) spectroscopy was used to study the mobility and t…

Création au féminin. Vol 3: Filiations

2007

Si tout artiste peut utiliser dans son oeuvre ses relations avec son père et sa mère biologiques, les écrivaines et femmes artistes, après n'avoir longtemps appartenu à aucune tradition, ont aujourd'hui le redoutable privilège de pouvoir prendre appui sur les pères (ou s'opposer à eux), mais aussi sur les mères que le mouvement féministe des années 1960-70 et avant lui Virginia Woolf ont redécouvertes et remises à l'honneur. Ce recueil se penche sur les difficultés multiples des créatrices et sur les stratégies qu'elles ont élaborées à différents moments de l'histoire artistique et littéraire du monde occidental, pour s'affranchir des contraintes et répondre à un manque.

La facilitation, une pratique reconnaissant l'exclusion ; pour une réversibilité du phénomène ?

2022

La facilitation est une méthode de gestion visant la co-construction par un groupe d'une production en intelligence collective. L'animation de cette production est encadrée par une personne externe au groupe appelée « facilitateur » dont la volonté est d'inclure les participants dans une dynamique de faire ensemble. Que se passe-t-il alors quand le groupe comporte des exclusions ? Que peut la facilitation issue des sciences de gestion ? À partir d'un cas d'étude, la pratique de la facilitation est analysée en tant que processus inclusif qui voudrait tendre vers une réversibilité du phénomène à partir de la reconnaissance et de l'acceptation de l'exclusion et de la délibération contre l'excl…

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…

The aim of this study is the analysis of structure and transfer mechanisms through chitosan based food packaging materials with incorporated carvacrol as a model of antimicrobial active substance. Integration of composition parameters, structure, processing and drying of chitosan systems is correlated to its physico chemical and functional properties. Understanding and detailed analyses of processing parameters is crucial in production of active chitosan coatings applied on conventional materials such as polyethylene. So, the knowledge of composition and microstructure in association to environmental conditions, control the retention and the release kinetics of carvacrol from chitosan film.…
