Consumer Psychologist Dr. Catherine Jansson-Boyd of ARU and her team had 88 people rate six types of oat biscuits on healthiness, tastiness, crunchiness, chewiness, pleasantness, and likelihood of purchase based on visual appearance.
The results: Biscuits with a pronounced surface texture were seen as healthier and less tasty than biscuits with a smooth texture—and less likely to be purchased than biscuits with a smooth texture. Having a “healthy looking” texture decreases perceived tastiness and likelihood of purchase.
