摘要: 以南瓜籽为原料,采用微波和超声波对南瓜籽油的萃取进行了对比研究,采用正交法探讨了两种方法的最佳萃取条件和参数。结果表明:微波萃取最佳工艺参数为:溶剂为石油醚,物料与溶剂的质量比为1:7,辐射累计时间为7min,功率为640W,油脂提取率达39.98%;超声波萃取最佳工艺参数为:溶剂为石油醚,物料与溶剂的质量比为1:7,浸泡时间为24h,油脂提取率达38.77%。

Abstract: The microwave and ultrasonic methods were used to extract pumpkin seed oil respectively,and their extraction conditions were optimized by orthogonal test. The results showed that the optimal conditions of the microwave extraction are as follows: petroleum ether as extraction solvent,mass ratio of raw material to extraction solvent 1:7,microwave irradiation time 7 min and power 640 W. For the ultrasonic extraction,they are as follows: petroleum ether as extraction solvent,mass ratio of raw material to extraction solvent 1:7 and soaking time 24 h. The oil extraction rates are 39.98 % and 38.77 % for the microwave and ultrasonic extraction methods under the optimal extraction condtions,respectively.

Key words: pumpkin seed oil, microwave extraction, ultrasonic extraction, orthogonal test
