中文摘要:

      目的 本研究聚焦于构建适用于上海地区地产葡萄的品质评价体系,旨在通过科学的方法筛选出关键特征品质指标,并制定严谨的分级与评分标准。方法 通过对4个葡萄品种的57批次样品进行14项感官及内在营养指标的测定分析,运用因子分析筛选出可溶性固形物、总酸、固酸比、酒石酸、葡萄糖、锌、维生素C和花青素8项核心指标。基于聚类分析和层次分析法(AHP),明确了三级分级标准及权重分配,进而构建综合评分体系。结果 研究结果表明,巨玫瑰品种综合评分最高(95分),显著优于其他品种(阳光玫瑰、醉金香、申园)。结论 本研究所建立的评价体系具备较高的判别准确性,能够为上海地产葡萄的品质分级、品种优化以及市场推广提供可靠的科学依据。

英文摘要:

      Objective? This study is dedicated to constructing a quality evaluation system for locally - produced grapes in Shanghai. The objective is to screen key characteristic quality indicators and establish scientific grading and scoring standards through scientific methods. 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? The results show that the "Ju Meigui" variety had the highest comprehensive score (95 points), which was significantly superior to other varieties ("Yangguang Meigui", "Zuijinxiang","Shenyuan"). 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.
