摘　　要：建立刺梨果汁类产品品质综合评价体系,为贵州刺梨加工产品推广宣传提供参考。以贵州不同地区生产的14份刺梨果汁产品为试材,测定了包含可溶性固形物、蛋白质、可溶性糖及可滴定酸在内的基础品质指标,以及6种有机酸和超氧化物歧化酶(Superoxide Dismutase,SOD)、类黄酮和总酚3种活性物质含量,对21个品质指标进行相关性、主成分分析及系统聚类。综合21个指标分析共获得4个主成分,累积贡献率达92.77%,包含了所检品质中绝大部分指标信息,建立了刺梨类果汁产品品质综合评价模型为F=0.640×F_(1)+0.142×F_(2)+0.090×F_(3)+0.056×F_(4);在类间距离为18时,14份供试样品被聚为3类,第1类聚集了7份样品,其抗坏血酸、活性物质SOD、类黄酮和总酚以及元素含量较高,糖含量较低;第2类仅有1份样品,但其活性物质、可滴定酸和可溶性蛋白质含量最高;第3类聚集了其余6份样品,特点是固酸比、糖酸比较高,其余指标排名较为靠后。14份样品综合品质由高到低依次为:YPC>JHJ>YGT>YAJ>YGW>YSY>YSC>YPT>JPY>JGS>JPL>JPS>JSQ>JSJ。To establish a comprehensive quality evaluation system and also provide reference for promotion of processing products of Rosa roxburghii Tratt.in Guizhou.The basis of quality indexes,including soluble solids,protein,soluble sugar and titratable acid,and 6 kinds of organic acids and superoxide dismutase,flavonoids and total phenols content,were determined.The principal component analysis,correlation analysis and systematic clustering of 21 quality indexes were carried out.It showed that,by principal component analysis,four principal components were obtained,and the cumulative contribution rate reached 92.77%.The comprehensive evaluation model was established as F=0.640×F_(1)+0.142×F_(2)+0.090×F_(3)+0.056×F_(4).In addition,the 14 samples were grouped into three categories when the interclass distance was 18.Furthermore,category I contained 7 samples,which had higher content of ascorbic acid,SOD,flavonoids,total phenols and elements,but lower content of sugar.The second type had only one sample,but its active substance,titratable acid and soluble protein content was the highest.The remaining 6 samples were clustered in categoryⅢand characterized by high solid-acid ratio and high sugar-acid ratio.However,the other indexes were ranked relatively low.Based on the comprehensive quality score,the ranking of the 14 samples was:YPC>JHJ>YGT>YAJ>YGW>YSY>YSC>YPT>JPY>JGS>JPL>JPS>JSQ>JSJ.
