Revisiting sugar-fat mixtures: sweetness and creaminess vary with phenotypic markers of oral sensation.

abstract：:Olfaction involves a dual sensory process for perceiving odors orthonasally (through the nostrils) and retronasally (through the mouth). This investigation entailed developing a measure of sensitivity to an odor delivered in an orally sampled food (orange flavoring in a sucrose-sweetened gelatin) and examining sensiti...
