选取5种具有代表性、稀土含量不同的六堡茶进行稀土浸出率的研究。对照六堡茶地方标准中感官检验要求的冲泡方法,利用ICP-MS测定六堡茶冲泡过程中16种稀土元素的总浸出率,同时对六堡茶茶汤摄食安全性进行评估。研究表明,六堡茶冲泡过程中16种稀土元素的浸出率均在24%以下,根据ADI的参考值,处于较低的暴露水平。因此,建议六堡茶中稀土限量放宽到6mg/kg。 Five kinds of representative, rare earth content of Liubao tea rare earth leaching rate of the study. The total leaching rate of 16 rare earth elements during the brewing of Liubao tea was determined by ICP-MS, and the food safety of Liupo Cha tea was evaluated. The results showed that the leaching rates of 16 rare earth elements during the brewing process of Liubao tea were both below 24%, which were at a lower level of exposure according to the reference value of ADI. Therefore, it is recommended to relax the rare earth loofah tea limit to 6mg / kg.
