摘要:

针对假酸浆子胶质的提取,以水为提取溶剂,通过单因素试验选取试验因素与水平,根据Box-Behnken的中心组合试验设计原理,在单因素试验的基础上采用三因素三水平的响应面分析法,依据回归分析确定各工艺条件的影响因素,以胶质提取率为响应值作响应面和等值线图。结果表明,料液比、温度、浸提时间对胶质提取率都有显著影响,提取工艺条件为温度63℃、浸提时间50min、料液比1:8.7、浸提3 次时,胶质提取率达到极大值。此条件下胶质提取率预测值为10.658%,验证值为10.635%。

Abstract:

With water as the extractant, experiment factors and levels were firstly selected by single-factor tests to study the extraction of gum from Nicandra Physaloides (L.) Gaertn 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 gum as the response value. Experimental results indicated that the ratio of seed mass to water, extraction temperature and extraction time affect the yield of gum. When the extraction parameters are composed of 63 ℃, 50 minutes and 1:8.7 of seed mass to water, three-time extraction, the yield of gum is the maximum with predicted value of 10.658% and verified value of 10.635%.

Key words: Nicandra physaloides (L.) Gaertn seed gum, extraction, response surface analysis
