Abstract

Tannic acid, total, complexed and ionized fluoride, calcium, total phosphate, zinc, aluminium, copper, iron, mercury and manganese were determined in infusions prepared from some or all of 30 brands of tea. Mercury and copper were not detected. Significant positive correlations were observed between fluoride, aluminium and manganese. The low reactivity of fluoride in tea infusions with powdered hydroxyapatite compared with that in dilute sodium fluoride solutions may be in part explained by the presence of aluminium and manganese.

摘要

对30个品牌茶叶中的部分或全部冲泡液测定了总单宁酸、络合态和离子态氟化物、钙、总磷酸盐、锌、铝、铜、铁、汞和锰。未检测到汞和铜。观察到氟化物、铝和锰之间存在显著正相关。与稀氟化钠溶液相比，茶叶冲泡液中氟化物与粉末状羟基磷灰石的反应性较低，这可能部分归因于铝和锰的存在。
