超临界CO_2萃取野生杏仁油的试验研究
|
摘要
采用超临界CO_2萃取法提取野生杏仁油,通过单因素试验和正交试验对提取工艺进行优化。试验结果表明,影响野生杏仁油萃取率的主要因素顺序为:萃取压力>萃取温度>萃取时间,最佳工艺条件为:原料颗粒度40目,萃取压力26 MPa,萃取温度45℃,萃取时间3 h,该条件下野生杏仁油提取率达到42%～45%。
Wild almond oil was extracted by supercritical CO_2 extraction,and the extraction process was optimized by single factor test and orthogonal test.The main factors affecting the extraction rate of wild almond oil were as follows:extraction pressure>extraction temperature>extraction time and the best technological conditions.The best technological conditions were raw material particle size 40 mesh,extraction pressure 26 MPa,extraction temperature 45 ℃,extraction time 3 h.The extraction rate of wild almond oil under this condition reached 42% ～ 45%.
