Flavor

Dr. Etiévant is the director of the Nutrition, Chemical, Food Safety and Consumer Behaviour Divisions of The French National Institute for Agronomic Research (INRA) Elisabeth Guichard is recognised as an expert in flavour analysis by the scientific community as demonstrated by her publications in peer review Journals (180) mainly in Food Science, her active participation as oral speaker (130) or by poster presentation (123) in the most famous congresses in the field and her position as associate editor in Flavour and Fragrance Journal. She is editor of 8 books and author of 72 book chapters. She developed innovative methodologies to better understand the interactions between aroma compounds and macromolecules at the molecular level in the aim to predict aroma release from food matrix taking into account their initial composition. Since 2008, E. Guichard focused her research on the dynamic release of aroma compounds during food consumption by human subjects differing in their oral physiology and its impact on dynamic sensory perception. She also studied odor-taste associations to restore taste perception in low salt/sugar/fat products. Christian Salles is research director at INRAE. His main research field carries on in-mouth mechanisms leading to flavour release and perception with in vivo and in vitro approaches. He coordinated the development of chewing simulators dedicated to in vitro approaches of temporal flavour release and food breakdown studies in controlled eating conditions. He has coordinated several projects related to the reduction of salt content in food and in particular a European project (TeRiFiQ – from 1/2012 to 12/2015) on the reduction of salt, fat and sugar in food, with 17 European partners including 11 SMEs. These last years, he focused his research on the temporal release of sodium according to food matrix composition and oral condition. He is the author of 80 publications in peer-reviewed journals, 117 communications in scientific congresses (oral and poster) and the author of 53 book chapters. He is the editor of 2 books. Prof. Voilley is recognized worldwide for her extensive knowledge of mass transfer in small molecules, such as water or aroma, as a function of complex biological matrix structures, and their relationship with hydration level and processing. She has directed more than 50 PhD dissertations. She co-edited “Flavor: From Food to Behaviors, Wellbeing and Health” (Elsevier, 2016), and Flavour in Food (Elsevier, 2006). Prof. Voilley is Member of the French Academy of Agriculture.
