| 摘 要： | 选取山东、河南、湖北等地有代表性的10个山药品种,测定影响山药品种筛选的主要营养成分,然后对各指标进行主成分分析,通过主成分分析筛选出一种适宜糖尿病人食用的山药品种。结果表明,主成分分析法提取了5个主成分,累积贡献率达93.68%,可较好反映山药品质的绝大部分信息。快消化淀粉含量、多糖含量、直链淀粉含量、皂苷含量、淀粉含量为影响山药品质的主要因子。用5个主成分代替原来的12个品质因子对山药进行综合评判,在分析结果的基础上建立主成分综合得分模型,主成分综合得分最高的是长山细毛山药,为1.175。筛选出适宜糖尿病人食用的山药品种:长山细毛山药。

| Abstract: | In this study,10 typical yam cultivars from Shandong,Henan,Hubei Province were selected to investigate the main nutrients that influence cultivars selection of yam using principal component analysis(PCA). The main components were analyzed through principal component analysis,screening a suitable yam cultivars for diabetics.The PCA results showed that 5 principal components could reflect most details on yam with acumulative contribution rate of 93.68%.Ready digestible starch,yam polysaccharide,amylose were the main factors affecting the quality of yam. These 5 principal components rather than the original 12 quality factors were used in comprehensive evaluation of yam.On the basis of the analysis,the principal component comprehensive score model was established,and the highest score of the principal component was Changshan yam,with a score of the 1.175.Changshan yam were selected as the appropriate cultivars for diabetic patients. |
