Résumé : Fried sweetpotato from four varieties namely; Obare, Purupuru, Amuskwera and Abija/Kuffour was subjected to consumer acceptability tests (n= 61) in Bawku, Upper East Region of Ghana. Data on consumer demographics, consumer attitudes and sensory tests (Hedonic/Overall liking, Just About Right (JAR) and Check All That Apply (CATA)) were collected. Majority of consumers were women (69%) in the youthful age group of 18-35 years (68%). Consumers of fried sweetpotato in Ghana mostly consumed it two to three times a week (52%), in salted form (23%) and at lunch (75%). Four distinct consumer segments were realised namely; Purupuru dislikers (31%), All likers (41%), Obare dislikers (13%) and those who did not like Amuskwera (15%). In terms of hedonic test/overall liking, Obare (6.8) was most liked and closer to 'like moderately' and it was significantly different from the least liked Purupuru (5.7) which was in the region of 'like slightly'. All the four fried sweetpotatoes were rated JAR for mealiness, colour, sugariness and flavour by more than 50% of consumers however, only Obare (66%) and Abija/Kuffour (57%) had the appropriate crispiness. Regarding mapping of sensory characteristics using principal component analysis, the most liked Obare fried sweetpotato was described by the terms 'Good taste', 'Hard', 'Less sugary', 'Dry' and 'Crispy'. The information generated in this study can be used by breeders when developing new sweetpotato varieties with the required end-user characteristics for enhanced adoption.
