中文摘要: 以辣木籽为原料,通过超声辅助水酶法提取辣木籽油。以辣木籽油提取率为指标,利用单因素试验考察pH值、果胶酶添加量、提取时间、提取温度、超声功率对辣木籽油提取率的影响,在此基础上采用响应面法确定提取辣木籽油的最佳工艺条件。结果表明,最佳提取工艺为果胶酶添加量0.50%、pH3.5、提取温度54℃、提取时间12 h、超声功率84 W,此时辣木籽油提取率为30.56%。
Abstract:The Moringa oleifera seed oil was extracted by ultrasound-assisted aqueous enzymatic extraction with Moringa oleifera seed as raw material.The extraction rate was used as the indicator and the extraction condition was optimized by single factor experiments and response surface methodology(RSM).The optimum conditions were as follows:addition amount of pectinase 0.50%(based on Moringa oleifera seed mass),pH3.5,extraction temperature 54℃,extraction time 12 h,and ultrasonic power 84 W.Under these conditions,the extraction rate was 30.56%.
