Sorting of Oral Sensations

Completed

Conditions studied: Taste Qualities, Primary Tastes

In brief

Recent research indicates that fatty acids in food may have a taste. There is no lexicon to describe the sensation of the fatty acids, but participants frequently describe the sensation as bitter or sour. The proposed study will ask participants who have been screened for their ability to detect fatty acids to sort a variety of taste stimuli, including sweet, sour, salty, bitter, umami, and fatty acid tastes. Observing how the participants sort the stimuli will allow us to determine if the fatty acid taste is unique from other taste sensations.
