Research Study Details

Spanish Taste Perception

The Sensory Evaluation Center at Penn State is conducting a study to explore differences among native Spanish-speaking individuals from Central and South America in the way that they perceive various food components called chemesthetic agents, or compounds that produce touch sensations. Examples of these chemesthetic agents are carbonation in soda, tannins in wine, and the cooling of minty gum. We are interested in understanding how differences in language and culture may influence individual taste perception of chemesthetic compounds.
