找出灵宝,新郑,新疆3种枣中主要的营养成分及元素含量的区别。采用化学方法检测营养物质含量,用电感耦合等离子发射光谱仪检测3种红枣中的Ca,Mg,Cu,Fe,Co,Li,Zn,Se,Mn 9种常微量元素。结果显示:新疆大枣的VC、蛋白质、总糖、多糖、Se的含量明显高于其他2种;灵宝大枣脂肪、总酸度、黄酮、Ca、Fe、Mg、Zn、Co元素含量高于其他2种。3种枣果中,新郑大枣中Cu元素的含量最高。3种枣果相比,新疆大枣的营养物质含量丰富,灵宝大枣常微量元素含量丰富。

Difference of main nutritional composition and elements among lingbao,xinzheng,xinjiang jujube fruit was found out. [Methods]: The main nutrients content were detected by chemical methods. The content of Ca,Mg,Cu,Fe,Co,Li,Zn,Se,Mn were determined by inductively coupled plasma emission spectrometer. [Results]:In xinjiang jujube,VC,Protein,total sugar,polysaccharide,Se content were the highest among three kinds of jujube fruit. In lingbao jujube fruit,fat,total acidity,flavonoids content,the content of Ca,Fe,Mg,Zn,Co were the highest. Cu content in xinzheng jujube was the highest. [Conclusions]: Compared three kinds of jujube fruit,xinjiang jujube is rich in nutrients content,lingbao jujube is rich in elements.
