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…

Introduction et but de l’étude : L’impact environnemental et les risques pour la santé associés à la production et la consommation excessive de sources de protéines animales pourraient être limités par l’augmentation de la part des protéines végétales dans notre alimentation. Les protéines végétales sont parfois déficitaires en certains acides aminés (AA) essentiels. De ce fait, un mélange de protéines animales et végétales permettrait d’assurer une complémentarité en AA répondant aux besoins de l’organisme. L'objectif de cette étude était d'évaluer l'impact, sur la taille des protéines, de la formulation et des processus de transformation des gels laitiers enrichis en légumineuses et d’étu…
