Libération et perception de composés de la flaveur au cours de la mastication de bases fromagères
2005
National audience; Relier la libération de composés de la flaveur (arôme et saveur) en bouche à la perception de la flaveur est encore une tâche difficile. La libération de flaveur pendant la mastication et l’ingestion d’un aliment dépend de plusieurs facteurs tels que la composition et la texture de l’aliment, les paramètres de salivation et de mastication, la nature des composés de la flaveur. L’objectif de l’étude est de tenter de relier la libération de composés volatils et non volatils, et la perception de la flaveur en prenant en compte les paramètres respiratoires, masticatoires et salivaires au cours de la mastication d’une base fromagère. La mesure de paramètres physiologiques orau…
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 …

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…
