【摘要】 简述了茶多酚的应用情况 ,并研究了间接测定食品保鲜剂中茶多酚的原子吸收法。本测定方法是基于茶多酚能与碱式乙酸铅发生络合反应 ,产生难溶于水的黄色沉淀 ,经离心后 ,用原子吸收法测定上清液中过量的铅离子 ,由此可间接测定茶多酚含量。此方法准确、快速 ,可方便地应用于食品保鲜剂—茶多酚的测定更多还原

【Abstract】 In this paper,applation actuality of New Food Additive Green Tea Polyphenols was simply described,and a new indirect method for determining Green Tea Polyphenols by atomic absorption spectrometry is studied. The basis is Green Tea Polyphenols could react with Pb 2+ and lead to yellow precipitate.The precipitate is centrifuged to subside,the Pb 2+ in supernatant is determined by AAS,and the concentration of Green Tea Polyphenols is obtained.更多还原
