乌龙茶中的微量元素及其检测技术研究进展
乌龙茶不仅具有保健功效, 还具有一定的药理功能, 这与其含有丰富的生化成分与微量元素有着十分重要的关系。近年来, 微量元素与人体健康的关系成为了人们关注的热点之一。本文综述了微量元素对于人体健康的影响, 乌龙茶干茶和茶汤中微量元素含量的研究概况及其对人体健康的影响, 以及原子吸收光谱、电感耦合等离子体质谱法、电感耦合等离子体原子发射光谱法3种测定乌龙茶中微量元素的方法。通过比较, 3种方法都有各自的优点和缺陷, 在选择测定乌龙茶中微量元素含量的方法时, 最好多种方法结合使用, 以提高测定效率及测定的精确度。通过对乌龙茶中微量元素含量及测定方法的综述, 以期为研究乌龙茶中微量元素含量的方法提供参考, 为建立更加合适的茶叶中微量元素营养价值评价体系提供参考。

Oolong Tea not only has the function of health care, but also has the pharmacological function, which is related with its biochemical compositions and the rich trace elements. In recent years, the relationship between trace elements and human health has become one of the focused attentions of the people. This paper reviewed the effects of trace elements for human health, the content of trace elements in Oolong tea and tea soup, and its impact on human health. It also compared 3 kinds of determination methods of trace elements in Oolong tea, including atomic absorption spectrometry, inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectrometry. It found that 3 methods had their own advantages and disadvantages. In selecting the method for determining the content of trace elements in Oolong tea, it is preferable to use a combination of various methods to improve the measurement efficiency and the accuracy of the measurement. Based on the review of the content of trace elements in Oolong tea and the determination methods, this paper provides references for the study of the content of trace elements in Oolong tea and the establishment of more suitable evaluation system of trace elements in tea.
