摘要:

采用超声波法提取南瓜籽油,筛选了提取南瓜籽油的理想溶剂,通过单因素试验和正交试验考察了提取温度、提取时间、液料比、超声频率和功率对南瓜籽油得率的影响,结果表明:石油醚为提取南瓜籽油的理想溶剂;各因素对南瓜籽油得率的影响大小依次为:液料比>超声时间>超声温度>超声频率和功率;优化的提取工艺参数为:液料比6:1(V/W)、超声频率和功率59kHz、280W、提取温度60℃、提取时间35min,此条件下无壳瓜籽油的得率达39.04%。

Abstract:

Pumpkin seed oil was extracted by ultrasound method, in this study. Effects of extraction solvent, extraction temperature, and extraction time, ratio of liquid to material, ultrasonic frequency and power on oil yield were investigated by single-factor test and orthogonal design. The results showed that the optimal extraction solvent is petroleum ether. The significance sequence of other five factors affecting oil yield is as follows: ratio of liquid to material > extraction time > extraction temperature > frequency and power of ultrasound, and their optimum levels are 6:1 (V/W), 35 min, 60 ℃, 59 kHz and 280 W, respectively. Under these conditions, the oil yield reaches 39.04%.

Key words: pumpkin seed oil, ultrasound-assisted extraction, orthogonal test
