以脱脂油茶籽粕为原料,研究从油茶籽粕中提取茶多糖的优化工艺,对提取工艺中液料比、乙醇浓度、浸提温度和浸提时间分别进行了单因素实验,以考察各单因素对茶多糖得率的影响。在单因素实验的基础上利用4因素3水平的响应面法（RSM）建立二次回归模型,对4个因素进行优化组合,并对因素和因素间交互作用进行方差分析和响应面分析,从而确定从油茶籽粕中提取茶多糖的最佳工艺条件为液料比11:1、乙醇浓度60%、浸提温度55℃,浸提时间2 h。验证实验茶多糖实际得率为7.43%。最后,简要总结了提取出的粗茶多糖的分离纯化方法。工艺优化后茶多糖得率高、安全可靠、生产操作方便,为工业上茶籽多糖的提取提供了...

Using the degreased camellia seed meal as raw material, the extracting process of tea polysaccharide from the camellia seed meal was studied, the experiments were carried out to test the yield of tea polysaccharide affected by different factors which including the ratio of liquid to material, concentration of ethanol, extraction temperature and time. Then, on the basis of single factor experiments, the quadratic regression model was established by 4-variable 3-level RSM to optimize the four factors. At the same time, ANOVA and RSM analysis abou...
