    CO2超临界萃取技术提取被孢霉菌丝体油脂的研究

    Study on the Mortierella Mycelium Oil Extraction by Supercritical CO2 Fluid Technology

      摘要
    • 摘要: 采用被孢霉菌丝体作为实验材料，比较系统地研究了在超临界状态下，预处理条件（水分含量、粉碎方法、粉碎度）、萃取条件（萃取温度与压力）、分离条件（分离温度与压力）对油脂萃取率的影响；分析了操作条件对油脂质量特别是γ－亚麻酸（ＧＬＡ）的影响；确定了最佳工艺路线，为批量生产提供了依据。

       

      Abstract: Mortierella mycelium was taken as experimental material of extraction condition. In addition to the analysis of the effects of extraction condition on the quality of oil, especially, GammaLinolenic acid (GLA), this paper systemically studied the influences of preprocessing condition (moisture content,grind method, grind degree),extraction condition (temperature,pressure) and separation condition (temperature,pressure) on the extraction rate. The optical technique way was determined and the bases for batch process were provided.
