庐山云雾茶多糖提取工艺研究

摘要

采用正交试验研究了提取温度、时间、固液比等因素对庐山云雾中茶多糖产率的影响.试验表明：庐山云雾茶多糖的最佳提取工艺为：温度75℃，提取时间2 h 、固液比1∶35，庐山云雾茶多糖产率为4.58％.%The factors of extraction temperature , time , ratio of solid to liquid affecting the extraction rate of tea polysaccharides on Lushan mist tea were analysed using orthogonal test in this paper .The results showed that the best extraction technology of Lushan mist tea polysaccharides was as follows : the temperature of 75 ℃ ,2 hours of time ,the ratio of solid to liquid 1∶35 .The extraction yield was 4.58% .
