中文摘要:
      以冬瓜籽为原料，采用超声辅助水酶法提取冬瓜籽油。在单因素实验的基础上进行正交实验，得出最佳提取工艺条件:颗粒粒度60目，液料比7∶1，酶用量2.0%（以冬瓜籽质量计），pH 8.0，酶解温度55℃，超声时间20 min，超声功率150 W，超声温度50℃。在最佳条件下，冬瓜籽油提取率为82.55%。
英文摘要:
      The Benincasa hispida Cogn. seed oil was extracted by ultrasound-assisted aqueous enzymatic method．On the basis of single factor experiment, the optimal extraction conditions were obtained by orthogonal experiment as follows: partical size 60 meshes, liquid-solid ratio 7∶?1, dosage of alcalase 2.0%（based on the mass of Benincasa hispida Cogn. seed）, pH 8.0, enzymolysis temperature 55 ?℃, ultrasonic time 20 min, ultrasonic power 150 W, ultrasonic temperature 50?℃. Under these conditions,the extraction rate was 82.55%.
