摘要
利用响应面法对罗望子胶的提取工艺进行优化。在单因素实验的基础上选取实验因素和水平,根据中心组合(Box-Benhnken)实验设计原理采用三因素三水平的响应面分析法,根据回归分析确定各工艺条件的主要影响因素,以多糖提取为响应值作响应面图。结果表明,罗望子胶的最佳提取工艺条件为:料液比1:40、pH4.4、沉降时间3h,在此条件下,罗望子胶的提取率预测值为53%,验证值为52%。
The optimum extraction conditions of tamarind gum from Tamarind seeds were obtained through Box-Behnken central combination design and Response Surface Analysis（RSM）.Experiment factors and levels were firstly selected by single-factor to study the extraction of tamarind gum from tamarind seeds.According to the Box-Behnken center united experimental design principles,the method of response surface analysis with 3 factors and 3 levels was adopted.Then the factors influencing the technological parameters were determined by means of regression analysis.Response surface and contour were finally graphed with the yield of tamarind gum as the response value.Experimental results indicated that the optimum extraction conditions of tamaeind gum were as follows：ratio of material to water 1：40,pH4.4,settling time 3h.Under such condition,the yield of tamarind gum was the maximum with predicted value of 53% and verified value of 52%.
