Sour Taste Intensity Matching With Fatty Acids Taste

March 9, 2021 updated by: Richard Mattes, Purdue University
Investigators are trying to find the concentrations of fatty acids ( a part of the fat and flavor typically found in normal foods) that have a taste intensity similar to that to the sourness of vinegar solutions.

Detailed Description

Participants will first taste 5 sour solution containing acetic acid for sour compounds, sucrose esters, and xanthan gum to help them stay dissolved). Then rate them for their taste intensities. Next, participants will taste 5 butyric acid solutions, 5 hexenoic acid solutions, 5 caprylic acid solutions, 5 lauric acid solutions, 5 palmitic acid solutions, 5 oleic acid solutions, and 5 linoleic acid solutions (all will also contain the sucrose esters and xanthan gums.) and rate them for their taste intensities. This should take no longer than 1 hour. Participants will spit all samples into a cup after tasting them. They will not swallow any samples.
