摘　　要：对青岛崂山绿茶中9种矿质元素的溶出特性进行研究,考查了冲泡水温、浸泡时间和冲泡方式等因素对浸出量的影响。结果表明:不同元素的浸出量受冲泡水温、浸泡时间的影响不尽相同,但大部分元素在80℃～90℃水温下溶出量可达最大,而冲泡时间以30min为佳。煮茶时茶汁中元素含量相对较高,泡茶时第二泡浸出量仍可达第一泡的50%以上,证实了崂山绿茶具有营养丰富、耐冲泡等优点。The extracting characteristics of nine mineral elements in Qingdao Laoshan green tea have been researched, the effects of some factors like temperature, time and extracting methods on the extraction have been disscused. The results show that the extracted amount of different elements vary with temperature and time, hut most of elements can be extracted maximumly at 80℃～90℃,with the optimus time of 30min. The elements＇concentrations are relatively high in boiling tea juice ,and the second extracted contents of mineral elements can still reach to 50% of the first extraction,and indicting that the Laoshan green tea is adundant in mineral mutriton and draws well.
