摘要
应用超临界二氧化碳萃取技术,研究了肉桂皮油的提取工艺。探讨了萃取温度、萃取压力、二氧化碳流量、原料堆积密度等因素对肉桂油萃取得率的影响,采用四因素三水平的正交试验,得出肉桂的超临界二氧化碳萃取的最佳工艺条件为:温度40℃、压力35MPa、CO2流量30kg/h、堆积密度(0.44±0.02)g/mL,萃取物得率5.8%～6.0%,为水蒸气蒸馏法的5倍多,所萃取出的肉桂油外观为棕红色油状物,香气纯正。
Extraction technique of Chinese cinnamon oil by supercritical carbon dioxide method was studied.Factors affecting extraction yields,such as temperature,pressure,CO2 flow rate and bulk density of the raw material,were discussed.By orthogonal experiment,optimal technological conditions were achieved as follows:extracting temperature 40 ℃;extracting pressure 35 MPa;CO2 flow rate 30 kg/h;bulk density of raw material(0.44±0.02)g/mL.Oil yield obtained by this method is 5 times more than that by steam distillation method.The obtained cinnamon oil is of brownish red color with right pure odor.
