CO_2超临界萃取技术提取麦胚芽油的研究

Study on extraction condition of oil from triticums by CO 2 supercritical fluid

采用麦胚芽作为实验材料，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ＶＥ的影响；确定了最佳工艺路线，为批量生产提供了依据。

Triticums were taken as experimental materials of extraction condition. In addition to the analysis of the effects of extraction condition on the quality of oil, especially, V E, this paper has studied systematically the influences of pre processing condition(moisture content, grind methods, grind degrees), extraction condition(temperature, pressure) and separation condition(temperature, pressure) on the extraction rate. This optical technological way has also been determined and bases for batch process been provided.
