@@@@Tea polyphenols was extracted by ultrasonic wave technology with orthogonal test method.The effect of adsorption rate for tea polypehnols by using the beaded chitosan resin was studied.The results showed optimal extraction condition were as follows:the solid-liquid ratio 1∶15 (g/mL),the temperature of extraction 60℃, the time of extraction 21 min,and extract twice. Meanwhile the optimal adsorption condition to tea polyphenols were as follows:the beaded chitosan resin 4.0 g,adsorption time 2.0 h,adsorption temperature 30℃,pH of tea soup 7.The absortion rate could reach 70.95%.
