摘要
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.
