新疆6种辣椒籽中矿质元素测定及聚类分析

Mineral Content Determination and Cluster Analysis of Six Species of Hot Pepper Seeds Grown in Xinjiang

目的:分析不同品种辣椒籽中的矿质元素含量,并进行聚类分析,评价其营养价值。方法:采用电感耦合等离子体发射光谱(inductively coupled plasma-atomic emission spectrometry,ICP-AES)法测定Zn、Cu、Fe、Mn、Ca、Mg、Na、K。结果:辣椒籽中富含多种矿质元素,常量元素K/Na、Mg/Na比值高,微量元素Fe含量最为丰富,Zn、Cu含量相对较少,Zn/Cu比值在2.01～1.36之间;从元素含量的角度进行聚类分析,6个辣椒籽品种可以分为两大类。结论:辣椒籽中矿质元素含量高,具有食品开发的价值。

objectives： The mineral contents were determined in 6 species of hot pepper seeds grown in Xinjiang and a cluster analysis was conducted to evaluate their nutritional values.Methods： The contents of Zn,Cu,Fe,Mn,Ca,Mg,Na and K were determined by inductively coupled plasma-atomic emission spectrometry（ICP-AES）.Results： These species of hot pepper seeds were all rich in several mineral elements with high ratios of K/Na and Mg/Na,and the most abundant element was Fe,while Zn and Cu demonstrated a relatively smaller content,with a Zn/Cu ratio of 2.01 to 1.36.The 6 species of hot pepper seed could be divided into two groups from the perspective of mineral elements.Conclusions： As an abundant source of mineral elements,the species of hot pepper seeds grown in Xinjiang deserve to be developed into foods.
