摘要

儿茶素在决定绿茶的涩味和口感方面起着重要的作用。它也有一定的健康益处，这使得绿茶在人类中很受欢迎。本研究报道了用不锈钢电极检测儿茶素的方法。用循环伏安法对电极的感官评价与碳糊电极和铂电极进行了比较。电极在1 ~ 10μM的浓度范围内线性良好，R2值为0.99。为了确定电极的性能，本文还对真实的茶叶样品进行了探索。

Voltammetric determination of catechins in green tea using stainless steel electrode

Catechin plays a significant role in determining the level of astringency and taste of green tea. It has also certain health benefits which makes green tea very popular among mankind. This study reports the use of stainless steel electrode for the detection of catechin. The sensory evaluation of the electrode was compared with that of carbon paste and platinum electrode by means of cyclic voltammetry. The electrode also showed good linearity over the concentration range 1 to 10μM having R2 value of 0.99. Real tea samples are also explored herein to ascertain the performance of the electrode.
