摘要

对17个黑米品种、16个红米品种和30个白米品种进行了8种矿质元素、多酚以及直链淀粉含量的测定,结果发现,大量元素磷(P)的含量在有色稻米中的含量明显高于白米,其中在黑米中的含量最高;微量元素铁(Fe)、锰(Mn)、锌(Zn)、铜(Cu)的含量在有色大米中也明显高于白米。元素间的积累具有一定相关性,如钙(Ca)与钾(K),镁(Mg)与P,Fe与Mg、Ca、Cu、P,Mg与Mn、Ca,Mn与P都具有一定的相关性。有色米的多酚含量显著高于白米,且在红米中的含量最高。供试材料的直链淀粉含量都处于中低等水平,且白米和红米品种的平均直链淀粉含量均显著高于黑米。直链淀粉含量与多酚含量的相关性不显著。

Abstract

8 kinds of mineral elements content, polyphenol content and amylose content of 17 black rice varieties, 16 red rice varieties and 30 white rice varieties was measured in the experiment. The results showed that the contents of the macro-element P of colored rice was higher than that of white rice, the content of black rice was the highest. The contents of the micro-element Fe, Mn, Zn and Cu of colored rice were higher than that of white rice. This study showed that there was a certain correlation between different elements, such as, there was negative correlation between Ca and K, but there was positive correlation between Mg and P. Moreover, there were positive correlation for Fe and Mg, Ca, Cu, P; Mg and Mn, Ca; Mn and P. This study also found that the average polyphenol content of red rice was the highest. The average amylose contents of these rice were in a low and medium level, the average amylose contents of white rice and red rice were significantly higher than that of black rice. But there was no significant correlation between amylose content and polyphenol content.
