Optimization in Extraction of Tea Polyphenols from Qingzhuan -Brick Tea by Response Surface Methodology
摘要
Abstract
The tea polyphenols from Qingzhuan tea were extracted by water solvent .Based on the sin‐gle-factor extraction tests ,Box -Benhnken Design module and response surface methodology were employed to optimize the extraction conditions for the tea polyphenols from Qingzhuan tea .Results demonstrate that the optimum extraction conditions for the tea polyphenols were as the following :liq‐uid-solid ration 40 :1(V/m) ,extraction time 85 minutes and extraction temperature 80 ℃ .Under such optimum conditions ,the theoretical extraction rate was 3 .38% ,while the actual extraction rate of the tea polyphenols was 3 .42% with the relative error of 1 .18% ,indicating that the response sur‐face methodology was feasible to optimize the extraction of the tea polyphenols from Qingzhuan tea by means of w ater solvent .关键词
