摘要: 【目的】分析不同地域来源猕猴桃有机成分组成特征及含量差异,各有机成分指标对猕猴桃产地来源的判别效果,探讨有机成分指纹分析技术对猕猴桃产地鉴别的可行性。【方法】检测来自陕西周至和眉县、四川沐川、湖南永顺3个主产区93份猕猴桃样品的VC、VE、可溶性固形物、总酸及总糖含量,分别对数据进行方差分析(ANOVA)、多重比较分析和判别分析。【结果】不同产地猕猴桃的有机成分指纹信息有显著差异。陕西周至和眉县猕猴桃的VC含量最高,VE、可溶性固形物及总糖含量最低;四川沐川样品的VE、可溶性固形物及总糖含量最高,总酸含量最低;湖南永顺样品的总酸含量最高,VC含量最低。利用VC、VE、可溶性固形物、总酸及总糖含量对猕猴桃产地进行判别分析,回代检验正确判别率为92.2%,交叉检验正确判别率为90.0%。【结论】不同地域来源的猕猴桃有其独特的品质特征,有机成分指纹分析是用于猕猴桃产地鉴别的一种潜在技术。

Abstract: 【Objective】The organic compounds characteristics and content differences in kiwi fruit from different regions were analyzed, and the validity of indicators for kiwi fruit origin discrimination was assessed, the aim is to explore the feasibility of organic compound fingerprinting in distinguishing the geographical origin of kiwi fruit.【Method】The contents of VC, VE, soluble sugar, total acid, and total sugar were determined in ninety-three samples from Shaanxi (Zhouzhi, Meixian), Sichuan (Muchuan) and Hu’nan (Yongshun) provinces of China, and analysis of variance (ANOVA), multiple comparison analysis, and discriminant analysis (DA) were applied in data analysis. 【Result】The contents of the organic compounds were significantly different in kiwi fruit from different regions. The content of VC was the highest, and those of VE, soluble sugar, and total sugar were the lowest in the samples from Zhouzhi and Meixian, Shaanxi provinces. While the contents of VE, soluble sugar, and total sugar were the highest, and that of total acid was the lowest in the samples from Muchuan, Sichuan provinces. Besides, the content of total acid was the highest and VC was the lowest in the samples from Yongshun, Hu’nan provinces. A linear discriminant analysis procedure produced a successful assignation (92.2% original classification, and 90.0% cross validation)of kiwi fruit according to the region. 【Conclusion】Kiwi fruit samples from different regions have their unique quality characteristics. It is a potential technology that determine the geographical origin of kiwi fruit using organic compound fingerprint analysis.
