Consumer perception of purple-fleshed sweet potatoes: hedonic, sensory, and emotional expectations
Purple-fleshed sweet potatoes (PFSP) are a new product for Uruguayan consumers. It shows differentiable sensory characteristics and added nutritional benefits, but sensory and hedonic expectations raised by PFSP have not been explored yet in Uruguay. The aim of this work was to explore Uruguayan consumers' perception of PFSP with a special focus on the hedonic, sensory and emotional expectations raised by them in comparison to traditional yellow and orange-flesh genotypes available in the market. A series of pictures of three types of SP were used in a social-network-driven study completed by 179 SP consumers. A word-association task and rating of expected liking together with exploring how they would feel after consumption using a check-all-that-apply (CATA) question composed of 21 emoji were carried out. Participants were also asked to describe the expected sensory characteristics using a CATA questions composed of 17 terms, selected based on results from previous sensory studies. Results revealed a lack of consumer familiarity with purple flesh coloration and lower expected liking scores compared to traditional orange and yellow flesh genotypes. It was also associated with scarce positive hedonic and emotional associations related to the emojis flushed face, face screaming in fear, grimacing face and weary face. Moreover, they were expected to have similar characteristics to yellow-fleshed sweet potatoes (YFSP) in terms of texture and flavor, being also associated with off-flavors presence. This highlights the need to develop diverse marketing strategies to increase familiarity before the commercial release of PFSP.
