浙江红山茶茶籽饼中茶皂素提取工艺研究

目的]为浙江红山茶茶籽饼中茶皂素的开发利用提供帮助。方法]以浙江红山茶茶籽饼为材料,通过单因素试验和正交试验研究乙醇浓度、温度、时间和液料比对茶皂素提取的影响。结果]各因素对茶皂素提取的影响大小为乙醇浓度提取时间液料比提取温度;最佳提取工艺条件:乙醇浓度为80%,液料比为3∶1 ml/g,提取时间为5 h,温度为70℃。结论]确定了浙江红山茶茶籽饼中茶皂素的最佳提取工艺。

Study on the Extraction Technology of Tea Saponin from Camellia chekiang-oleosa Hu Tea Seed Cake

Objective] To supply help for extraction of tea saponin from Camellia chekiang-oleosa Hu tea seed cake.Method] With Camellia chekiang-oleosa Hu tea seed cake as material,the effects of ethanol concentraction,liquid-solid ratio,extraction time and extraction temperature on extraction of tea saponin were studied through single factor test and orthogonal test.Result] The effects of various factors on extraction of tea saponin were shown as ethanol concentration> liquid-solid ratio> extraction time>extraction temperature.The optimum technical extraction conditions were as follows: ethanol concentration was 80%,liquid-solid ratio was 3∶ 1,the extraction time was 5 h and the temperature was 70 ℃.Conclusion] The optimum extraction technology of tea saponin from Camellia chekiang-oleosa Hu tea seed cake was confirmed.
