The general theme of this research is to understand the basic sensory mechanisms that underlie human flavor perception and the role of sensory perception in ingestive behavior. The perception of flavor consists of taste, retronasal odor, and somatosensation. Unfortunately, these components are not easily separated from one another, making it difficult to understand how they interact with each other in mixtures and more importantly, how they merge to form the perception of food “flavor”. In addition, despite the obvious role of oral sensory perception in establishing food preference and selection, little is known about how its various components contribute to hedonic responses to foods.
The long term goals of this research are thus to investigate 1) the sensory mechanisms of taste-odor interactions, 2) the perceptual and/or functional factors that are related to such interactions, 3) how each flavor component affects hedonic responses to foods, and 4) how individual differences in oro-nasal sensitivity play a role in food preference and choice.
