摘要
该文通过单因素试验和RSA响应面分析法优化了超声波辅助提取沙棘籽油的工艺方法,探讨不同提取剂、提取剂用量、提取时间、次数、功率对提取效果的影响。结果表明,超声波提取沙棘籽油的最佳条件为:以石油醚为提取剂,超声波功率为800 W,提取时间17 min,料液比为1∶9。该条件下,沙棘籽毛油的提取得率可达到9.27%;沙棘籽油中维生素E含量较传统方法提取的沙棘籽油高25%。
The optimum conditions of ultrasound-assisted extraction for seabuckthorn seed oil were determined by the single-factor experiment and the response surface analysis. The effects of different solvents, amount of extraction, extraction time, repeats and ultrasonic power were explored. The results show that the optimum extraction conditions were that petroleum ether as the best extraction solvent, ultrasonic power 800 W, extraction time 17 minutes and the liquid/solid ratio of 9 to 1. Under these conditions, the extraction rate for the crude seed oil of seabuckthorn reached 9.27 %. The proportion of vitamin E by ultrasound-assisted extraction was 25 % higher than that by the traditional process.
