Lujiu is a type of traditional Chinese liquor made from distilled liquor or fermented wine, and is blended, flavored or reproduced with additives, edible food materials, and/or medical herbs. The present study focused on consumers’ sensory perception and acceptance of Lujiu. Explicit self-report and implicit method using facial expression analysis were incorporated in this study. Consumers were invited to evaluate three Lujiu samples with different alcohol content and sugar content. They were video recorded during each evaluation session and their facial expressions were analyzed using FaceReader. The evaluation process was divided into four sessions of looking, smelling, tasting and after-tasting. ANOVA and MFA (Multiple Factor Analysis) were used in data analysis. The result showed that consumers gave high positive emotional responses such as happiness and surprise when tasting samples with high sugar content (95 g/L), which was consistent with the results of the preference questionnaire, indicating that products with higher sugar content were more popular. MFA results showed that sweetness, mouthfeel and fruitiness were closely related to acceptance, which was in accordance with the higher scores of the samples with high sugar content in sweetness, fruity aroma, soft and harmonious taste. The incorporation of facial expression and sensory evaluation was proven to be an effective and comprehensive method in measuring consumers’ affective response in Lujiu evaluation. This study established an effective method to evaluate the consumer acceptance of Lujiu through facial expression analysis technology, and provided a basis for further research.
