A new study this month by Purdue University found that a new essential taste is fat, in addition to the five that have already been discovered. The five that currently exist are sweet, sour, salty, bitter and umami (a rich, savory taste).
The taste of fat is often described as bitter or sour, reported Erica Gonzales for Yahoo!. Most people in the study were unable to find a word to describe the taste of fat.
“By building a lexicon around fat and understanding its identity as a taste, it could help the food industry develop better tasting products and with more research help clinicians and public health educators better understand the health implications of oral fat exposure,” Richard D. Mattes, professor of nutrition and co-author of the study, reported to Gonzales.
