| 摘 要： | 研究了富硒玉米子粒中硒的分布规律和赋存形态。结果表明,在供试玉米中,硒主要以有机结合态的形式存在,其含量占总硒的比例接近90%;在有机态硒中蛋白质硒含量较高,多糖中硒的含量较低;在蛋白质硒中以碱溶蛋白质中硒的含量为最高,占总硒的50.62%。因此,在富硒玉米的深度开发中,碱溶的弱酸性组分适用于深加工,成为补硒食品或添加剂。

| Abstract: | This paper studied on the distributed rule and distributed form of the selenium in the rich selenium corn grain. The results indicated that the selenium content approached to 90% from the organic matter in the analyzed corn. Quantities of selenium in protein were more, less in the polysaccharide. The main species of selenium in protein, and the selenium of acidic protein occupied the total selenium 50.62%. Therefore, in the rich selenium corn grain further development, the weak acid component may use to process into rich selenium food. |
