应用主成分分析法对11种山核桃的20个理化品质指标(含仁率、含油率、粗蛋白质含量等)进行分析,以各项指标累积方差贡献率达到85%以上为标准确定了5个反映山核桃理化品质的主成分,并对11种山核桃加工品质进行初步评价。结果表明: 云南5、云南4、云南3品种的山核桃加工品质较好,适宜于多种产品的加工。

Twenty physicochemical quality indexes (kernel content, oil content, crude protein content etc.) of eleven kinds of China pecans were analyzed by principal component analysis. Five principal components reflecting physicochemical quality of China pecan were determined with contribution rate of accumulative variance of each index above 85% as the standard, and the processing qualities of eleven kinds of China pecans were preliminarily evaluated. The results showed that the processing quality of Yunnan 5,Yunnan 4 and Yunnan 3 were better...
