Our research group explores the mechanisms at the origin of sensory perception of foods using different approaches.
A molecular approach is conducted to identify and characterise odorant molecules and to understand their interaction with macromolecules of food or saliva, in simple or complex systems.
A psychophysical approach is used to understand the representation of mixtures of odorants and multimodal interactions.
A neurobiological approach is conducted to identify cerebral, sensitive and cognitive mechanisms of food mental representation. A biomechanical approach is applied to understand in vivo release mechanisms of flavour compounds in the mouth during food mastication, taking into account interindividual variability of physiological parameters, and to validate their impact by in vitro studies with a chewing simulator.
A biochemical and molecular approach is conducted to understand the role of saliva in sensory perception and consumer behaviour, more specifically by studying enzymatic activities, proteome, peptidome and metabolome.

Key words : Flavour, release, food, saliva, perceptive interactions, molecular structure, biochemistry, physiology.

Thematic : our aim is to better understand the mechanisms leading to the release of flavour compounds during food consumption and their impact on global sensory perception.

Research group in detail Open all the tabs

Our main objectives are to explore the mechanisms at the origin of and influencing food mental representation in human. The studied mechanisms are the following: food composition and structure, food bolus formation, oral physiology, in-mouth molecular interactions involving flavour stimuli, mixture effects and multimodal interactions at the nervous central level.

Theme 1 : Sensory properties of flavour stimuli alone and in mixture (odorants, taste and trigeminal compounds), multimodal interactions

  • - Identification of the key compounds of food flavour
  • - Representation of mixtures of odorants (elemental versus configural perception)
  • - Understanding the mechanisms involved in multimodal interactions (physico-chemical, cognitive)

Theme 2 : Retention/release mechanisms of flavour stimuli (odour, taste) and their perception as a function of food and individual

  • - Role of oral physiological parameters and of their interindividual variability on food breakdown and flavour release
  • - Relationships between kinetics of in vivo flavour release and temporal perception
  • - Dissociate and prioritise in-mouth mechanims by in vitro approaches (chewing simulator, saliva reactor)
  • - Role of specific salivary proteins and enzymes in flavour release from food bolus and perception

Theme 3 : Molecular interactions between flavour compounds and biological targets

  • - Retention/release mechanisms of aroma compounds in food matrix (including with saliva) by molecular properties
  • - Interactions between flavour compounds and purified and well characterized salivary proteins, alone or in mixture
  • - Interactions between flavour compounds and oral mucosa

Theme 4 : Modulation of oral physiological parameters (stimulation, age, environment)

  • - Effect of salivary composition (proteins, enzymes) on food bolus formation
  • - Variability in saliva properties in relation to sensory variability (perception, preferences)
  • - Sources of biological variability: sensory stimulations, age, diet…
