Objective To construct a quality evaluation system for locally-produced grapes in Shanghai based on the key characteristic quality indicators. Methods By measuring 14 sensory and internal nutritional indicators of 57 batches of samples from 4 grape varieties, factor analysis was employed to screen out 8 core indicators, including soluble solids, total acids, solid-acid ratio, tartaric acid, glucose, zinc, vitamin C, and anthocyanins. Based on cluster analysis and the analytic hierarchy process (AHP), a three-level grading standard and weight distribution were determined, and a comprehensive scoring system was constructed. Results Results showed that the quality indicators of soluble solids, glucose, vitamin C and anthocyanins were relatively high in “Ju Meigui” variety, which had the highest average comprehensive score (81.6 points), and was significantly superior to “Zuijinxiang” (68.4 points), “Yangguang Meigui” (64.4 points), and “Shenyuan” (62.8 points). Conclusion The evaluation system established in this study exhibits high discriminant accuracy and can provide a reliable scientific basis for the quality grading, variety optimization, and market promotion of Shanghai-produced grapes.
