| 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。 |
| 关 键 词： | 食品保鲜剂 茶多酚 原子吸收法 测定 |

| 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. |
| Keywords: | new food additive green tea polyphenols atomic absorption apectrometry |
