天然富硒茶中除含硒元素外,还含有多种人体必需的矿物质元素。本研究采用ICP-AES法测定湖北恩施和安徽石台两个不同产地的富硒茶中铝(Al)、钙(Ca)、铜(Cu)、铁(Fe)、镁(Mg)、锌(Zn)、砷(As)、镉(Cd)、锰(Mn)、镍(Ni)、铅(Pb)和硒(Se)等十二种元素含量。结果表明,不同产地天然富硒茶中各种矿物质元素含量存在一定的差异,其中的Ca、Se等元素含量差异较大。研究结果为富硒茶中的矿物质含量检测提供了参考。
In addition to natural selenium tea selenium containing elements, but also contains a variety of essential minerals in the human body. In this study, the contents of Al, Ca, Cu, Fe, Mg and Zn in Se-enriched tea from Enshi, Hubei and Shitai, Anhui Provinces were determined by ICP- Zn, As, Cd, Mn, Ni, Pb and Se. The results showed that the content of various mineral elements in natural Se-enriched tea from different areas was different, and the content of Ca, Se and other elements were quite different. The results provide a reference for the detection of mineral content in Se-enriched tea.
