An automated method of total polyphenols analysis in apple juice using the Folin-Ciocalteu reagent is presented. Chlorogenic acid was selected as the standard since a similar kinetic behaviour, standard-sample, was observed. A straightforward method with good reproducibility (CV < 1%), sampling frequency (48 h-1) and correlation with the traditional batch method (r = 0.9924) is proposed.
本文介绍了一种使用福林-西奥尔特试剂自动分析苹果汁中总多酚的方法。由于观察到绿原酸具有相似的动力学行为（标准品-样品），因此选择绿原酸作为标准品。提出了一种具有良好重现性（CV<1%）、采样频率（48次/小时）且与传统分批法具有相关性（r=0.9924）的直接方法。
