目的优选复方药茶饮料的最佳提取工艺,为工业化生产提供依据。方法采用福林酚法测定药茶中茶多酚的含量并作为评价工艺的指标,响应面设计试验法优选复方药茶饮料最优提取工艺参数,单因素考察提取次数。结果药茶粉碎成20目,92℃热浸法提取2次,第1次加水量为药茶量的16倍,提取时间25 min;第2次加水量为药茶量的12倍,提取时间25 min。结论按此工艺制备复方药茶饮料可最大限度的保存茶香,提取工艺科学、合理、可行。

Objective To optimize the extraction process of Compound Herb Tea Drink, provide the basis for industrial production. Methods The tea polyphenols in tea as the evaluation index was determined by Folin phenol method. The extraction parameters of Compound Herb Tea Drink were optimized by the response surface design method, and the extraction times were investigated by single factor. Results The herb tea is crushed into 20 meshes, 92 ℃ hot dipping method for 2 times. The amount of water for first time is 16 times of tea, extraction time for 25 mi...
