| 摘 要： | 采用火焰原子分光光度法,测定了保定市市售的3种类型共16种蔬菜中的Ca、Cu、Zn、Fe、Mn 5种矿质元素,为指导人们日常饮食提供科学依据.结果表明:不同类型蔬菜中矿质元素含量不同,叶菜类蔬菜中的(Ca、Cu、Zn、Fe、Mn含量高于果菜类蔬菜、根茎类蔬菜;而不同品种的蔬菜其矿质元素的含量也存在很大差异,油菜中的Ca和Mn含量最高,分别为7.6 g/100g和8.98 mg/100g;Zn含量最高的为香麦16.72 mg/100g,其次为菠菜12.63 mg/100g,洋白菜的Zn含量最低仅为0.73 mg/100g;菠菜中Fe含量最高138.43 mg/100g,其次为香麦111.11 mg/100g.综合分析结果,香麦、菠菜、油菜的Ca、Cu、Zn、Fe、Mn含量要高于其它种类的蔬菜.

| Abstract: | This article determined the content of five kind of element of three kinds of vegetables by flame atomic absorption spectrometry,the elements include calcium(Ca),copper(Cu),zinc(Zn),iron(Fe),manganese(Mn).The result showed that the content of five elements of leaf vegetable was higher than fruit vegetable and earth vegetable.The content of Ca and Zn in cole were higher than other vegetables,which were 7.6 g/100g and 8.98 mg/100g.The zinc content in leaf-used lettuce was the highest(16.72 mg/100g),the second... |
