摘要: 在利用超临界CO2技术萃取大蒜风味成分的研究中,以正交试验对萃取温度、萃取压力、浸提时间、循环时间等对大蒜有效成分萃取率的影响进行了研究,此外还比较了萃取温度对萃取产物可分离特性的影响。结果表明,在一定的加料量和预处理条件下,萃取压力19MPa,萃取温度35℃,静态浸提50min,动态循环50min后,在分离温度为35℃,分离(I)压力8MPa,分离(II)压力6MPa下分离。萃取率较高,萃取物中大蒜精油的可分离度也相对较高。

Abstract: During the study of supercritical CO2 extraction of garlic, the extraction parameters were optimized by orthogonal test. The results indicated that under the designed optimal amount of influx and pretreatment conditions, a combination of extraction pressure 19 MPa and extraction temperature 35 ℃ proved optimal for the extraction efficiency, and later the garlic oil separation efficiency, provided that static soak time is 50 min and dynamic circulating time is 50 min, and a two-step separation method was employed, and the separating parameters were chosen as following: separator (I), 8 MPa, 35 ℃; separator (II): 6 MPa, 35 ℃.
