通过响应面分析法对大豆种皮中果胶的提取工艺进行优化.利用响应面实验设计考察pH值、提取温度、提取时间、和液料比四个因素对果胶得率的影响,探讨果胶提取的最佳工艺条件.通过响应面实验得出,pH值、液料比对果胶得率有显著影响,大豆种皮果胶提取的最佳工艺条为:pH1.54、提取温度89.9℃、提取时间90 min,果胶最大得率为8.37%.

To optimize the extraction process of the soybean hull pectin by response surface methodology .The influ-ence factors of extraction temperature,pH of HCl solution,extraction time and liquid-solid ratio were evaluated using a fractional design,to explore the optimum conditions of pectin extract .Obtained by experiment,both the pH of HCl solution and liquid -solid ratio had significant effects on the extraction rate ,the optimum conditions of pectin ex-traction were pH of HCl solution 1.54,extraction temperature 89.9℃,extraction tim...
