本研究以福建省武夷岩茶为研究对象,对武夷岩茶中稀土总量与16种稀土单质元素的含量及其溶出率进行分析与讨论。结果表明:武夷岩茶中稀土元素的溶出率较低,平均溶出率为13.100%;而武夷岩茶中的钇、镧、铈稀土元素含量为最高,溶出率分别10.900%、9.900%、15.800%。总的来说,武夷岩茶中稀土元素浸出率较低,武夷岩茶的稀土食品质量相对比较安全。
In this study, Wuyi Yancha in Fujian Province as the research object, Wuyi Yancha total amount of rare earth elements and 16 kinds of rare earth elemental content and dissolution rate were analyzed and discussed. The results showed that the dissolution rate of rare earth elements in Wuyi Yancha was lower and the average dissolution rate was 13.100%. The content of rare earth elements yttrium, lanthanum and cerium in Wuyi Yancha was the highest, with dissolution rate of 10.900%, 9.900% and 15.800% . In general, the leaching rate of rare earth elements in Wuyi Yancha is low, and the quality of rare earth foods in Wuyi Yancha is relatively safe.
