【摘要】 通过对水浸提法、有机溶剂沉淀法及超声波提取法提取南瓜多糖比较,结果以超声波法为最佳提取方法。进一步通过对超声波提取南瓜多糖工艺条件进行单因素和正交试验分析,得出最佳工艺参数:超声波功率400 W,料液比(g/mL)1∶4,作用时间28 min,提取温度60℃。更多还原

【Abstract】 This paper was studied on water extract method,organic solvent extraction method and ultrasonic wave extraction,and it was found that the ultrasonic wave extraction was the best.The optimum technological condition was determined,and the process parameters were that the power 400 W,the ration between pumpkin and water 1∶4,the ultrasound treatment time 28 min and the extraction temperature 60℃ through single factor and orthogonal experiment.更多还原
