桑叶绿茶中微量元素含量及浸出特征研究
Study on extracting characteristics and total content of trace element in mulberry green tea by FAAS
摘要
Abstract
The trace of elements such as cacium, magnesium, copper, manganese, zinc, iron in mulberry green tea were determined by flame atomic absorption spectrometry, each element extraction content in mulberry green tea were determined by different brewing time and different brewing times.The results showed that the order of each total element content was Ca.〉 Mg 〉 Fe 〉 Mn 〉 Zn 〉 Cu and the order of extraction rate was Mg 〉 Ca 〉 Zn 〉 Fe 〉 Mn 〉 Cu.The trace of element extracting characteristics in different brewing time can be described with logarithmic eauation, the characteristics in different brewing times can be described with exponential equation.The results could be as a theoretic basis for its depth exploitation.关键词
