Associations among fatty food sensations and saliva's emulsifying properties.

ABSTRACT: Individuals vary in saliva composition, which could in turn influence variability of oral sensations. This study was designed to investigate associations among saliva's ability to emulsify an oil/water mixture, fatty sensations, and diet. Participants (N = 62) gave sensory ratings for a white chocolate substitute with 0, 0.1, and 1% added linoleic acid. Discrimination sorting tasks were performed using the chocolate substitute with/without linoleic acid and with high/low-fat salad dressing. Participants swished and expectorated an oil/water mixture, and the size of the emulsified layer of this spat-out sample was measured. This novel technique was used to estimate the emulsifying ability of saliva, as oral swishing caused the fat to disperse into the water, stabilized by saliva. Estimated
