摘要: 以丰年虫为原料,利用超声波辅助法进行提取,筛选提取丰年虫油的最佳溶剂,选择超声波功率、料液比、提取时间和提取温度4个因素进行单因素试验,并在此基础上进行L27(313)正交试验。结果表明:超声波辅助提取丰年虫油的理想溶剂为乙酸乙酯,最佳工艺条件为超声波功率150W、料液比1:10(g/mL)、提取时间40min、提取温度60℃,在该条件下丰年虫的出油率可达84.83%。超声波辅助提取与溶剂法相比,有提取时间短、油脂品质较好等优点。

Abstract: This paper reports the optimization of process conditions for the ultrasonic-assisted extraction of oil from Chirocephalus diaphanous by one-factor-at-a-time and orthogonal array design methods. Ethyl acetate was found to be the most suitable solvent for Chirocephalus diaphanous oil among 5 solvents under investigation. The optimal extraction conditions were determined as 150 W of ultrasonic power, 1:10 of material/liquid ratio (g/mL), 40 min of extraction time, and 60 ℃ of extraction temperature. Under these conditions, the oil yield was 84.83%. The ultrasonic-assisted extraction method had the advantages of time-saving extraction and better oil quality over the traditional solvent extraction method.
