摘要
目的 :寻找超临界二氧化碳萃取药用大蒜油的参数。方法 :采用切片 .压榨 发酵和发酵醇提作为原料预处理 ,大蒜精油进行红外分析。结果 :可直接获得大蒜油 ,其最佳的提取工艺条件为 15MPa ,4 0°C ;大蒜油得率最高 ,可达 4 4 .5 7%。
Objective:To find out the coefficients of garlic oil by Supercritical Fluid Extraction (SFE). Methods: Cutting, squeezing fermentation and fermentation and ethanol extraction of garlic were respectively as pretreatments and then the use of supercritical carbon dioxide as an extraction and given garlic oil was analysed by means of IR. Result: Garlic oil can be directly extracted by SFE and its best operation condition was under the pressure of 15 MPa and at 40 °C extractability of garlic oil was up to 44.57% . Conclusion: Fermentation and ethanol extraction method is a best one for garlic oil obtained.
