Abstract: This study focused on dried sweet potatoes to develop a suitable sensory flavor evaluation method, where a sensory panel performed quantitative descriptive analysis on 41 commercial samples. The descriptive words were selected and summarized, a dried sweet potatoes gratin flavor wheel was constructed, and sensory evaluation tools were designed. A total of 67 descriptors words were obtained, and constructed a flavor wheel covering taste, odor, texture, and appearance. Using the geometric mean method combined with cluster analysis and principal component analysis, 29 characteristic descriptors were screened, including 5 for appearance, 6 for odor, 9 for taste and 9 for texture. The analytic hierarchy process determined the sensory indicator weight ratio as taste: texture: odor: appearance=40:35:10:15. Subsequently, two methods were established, including a suitability-based one for ordinary consumers and a quantitative descriptive one for professional evaluators. This study could provide a reference for the quality evaluation and product development of dried sweet potatoes.
