It shows differentiable sensory characteristics and added nutritional benefits, but sensory and hedonic expectations raised by PFSP have not been explored yet in Uruguay. 􀀹e 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 orangeflesh 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 a􀁂er 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. 􀀹is highlights the need to develop diverse marketing strategies to  \nincrease familiarity before the commercial release of PFSP. Keywords: consumers, breeding, sweet potato, texture, flavor.  \nResumen: Los boniatos de pulpa violeta (BPV) constituyen un producto novedoso para los consumidores uruguayos. Presentancaracterísticas fácilmente diferenciables, así como un valor nutricional añadido, pero aún se desconocen las expectativas sensoriales y hedónicas que generan en Uruguay. El objetivo de este trabajo fue explorar la percepción de los BPV con un focoespecial en las expectativas hedónicas, sensoriales y emocionales en comparación con los tipos tradicionales presentes en el mercado.
