摘要: :为优化超临界CO2萃取杜仲翅果油工艺参数,以杜仲翅果为原料,杜仲翅果油萃取得率为考察指标,采用控制单一变量法,分别确定超临界CO2萃取杜仲翅果籽油的最佳萃取温度、萃取压力、分离温度及分离时间,再通过正交试验及验证性试验,优化筛选最佳提取工艺。结果表明,影响超临界CO2 萃取杜仲翅果油得率的影响因素大小次序为:萃取温度>萃取时间>萃取压力>分离温度,最优萃取工艺技术参数为萃取温度35℃、萃取压力35 MPa、分离温度45℃、分离时间50 min,在该工艺参数下,杜仲翅果油的得率为14.73%,其中α-亚麻酸含量为61.37%。

Abstract: The paper aims to optimize the supercritical CO2 extraction of seed oil in Eucommia. Taking the samara of Eucommia as raw material, and the extraction ratio of samara oil as the index, by controlling the change of mono factors, the optimal extraction temperature, extraction pressure, separation temperature and extraction time were validated with supercritical CO2 extraction of Eucommia seed oil. And then, orthogonal design and verification experiments were conducted to determine the optimal extraction process. Factors influencing the extraction yield of oil in Eucommia were as follows: extraction temperature> extraction time>extraction pressure> separation temperature. And the optimum condition was obtained as follows: the extraction temperature 35℃, the extraction pressure 35 MPa, the separation temperature 45℃, the separation time 50 min. The yield of oil obtained under this condition with supercritical CO2 was 14.73%, and the α-linolenic acid accounted for 61.37% of Eucommia seed oil.
