研究了紫阳富硒茶硒赋存形态,用原子力显微镜观测紫阳富硒茶中茶多糖、碱溶性茶蛋白的结构形貌.结果表明：茶多酚硒占总硒的0.89%,蛋白硒占总硒的60.12%,多糖硒占总硒的18.06%,蛋白质组分中又以碱溶性蛋白结合硒含量最高,达到23.81%;观测表明,茶多糖为多侧支的树枝状结构,碱溶性蛋白主要以大小比较均一的杆状或球状结构存在.

This study is to investigate the combined forms of selenium in tea from Ziyang county.The structure of tea polysaccharide and alkali-soluble protein are investigated by atomic force microscopy（AFM）.The results showed that the ratio of selenium in tea polyphenol is 0.89% in total selenium comtent;the ratio of the selenium in tea protein and in tea polysaccharide is 60.12% and 18.06%,respectively.At the same time,Alkali-soluble protein seems to contain the highest amount of bound selenium,contributing to 23.81% of total selenium content.It is found that tea polysaccharide on mica shaped Multi-lateral branch-like structure by AFM,while the alkali-soluble protein existed in the form of size comparison uniform lever or spherical structure.
