| 摘 要： | 利用氢化物—原子荧光光度法分析硒在富硒茶叶中的主要赋存形态及分布规律。结果表明,富硒茶叶中的总硒含量为533.5μg/kg,硒主要以对人体有益的有机结合态形式存在,其含量占总硒的比例为83.66%,而有机硒中最主要的赋存形态为蛋白硒,占有机硒含量的76.35%,茶叶中的硒还有少部分与核酸和多糖结合。

| Abstract: | The combined forms, distribution rule and corresponding content of selenium in selenium-enriched tea were studied by using Atomic Fluorescence Spectrometer. The total selenium content was 533.5 μg/kg, and organic selenium was the main form storing in the tea, which accounted for 83. 66% of total selenium. The selenium in protein was the main organic selenium form, which accounted for 76. 35% , and part of selenium and the nucleic acid and the polysaccharide union were contained. |
