Title: Ultrasound-assisted Extraction and Fatty Acid Compositions of Pumpkin Seed Oil
Abstract: Pumpkin seed oil was extracted by ultrasound method. The optimal ultrasound-assisted extraction processing conditions were explored by single-factor and orthogonal experiments. Results indicated that the optimal extraction processing parameters were material-liquid ratio of 1:8 (g/mL), extraction time of 20 min, ultrasonic power of 90 W and extraction temperature of 30 ℃. Under these optimal extraction conditions, the extraction rate of pumpkin seed oil was up to 94.22%. The factor order for influencing extraction rate of pumpkin seed oil from strong to weak was material-liquid ratio, ultrasonic time, ultrasonic power and extraction temperature. The analysis of gas chromatography revealed that pumpkin oil mainly contained palmitic, oleic, stearic, linoleic and linolenic acids.
