摘要
目的:以杨梅核为原料,研究超临界CO2萃取杨梅核仁油的工艺条件。方法:采用正交试验,考察萃取压力、萃取温度、分离温度、萃取时间4因素对杨梅核超临界CO2萃取物得率的影响。结果:超临界CO2萃取杨梅核仁油影响因素次序为萃取时间>萃取温度>分离温度>萃取压力。结论:最佳萃取工艺条件为萃取温度45℃,分离温度55℃,萃取压力350 Bar(1 Bar=100 kPa),萃取时间3.5 h。此条件下杨梅核仁油得率为17.60%。
Objective： To study the supercritical CO2 extraction technique with myrica rubra nuclear as materials.Methods： The effects of extration pressure,temperature,separation temperature and extration time on nucleolus oil extraction yield were discussed by orthogonal experiment.Results： The influence of the four factors was in order of extraction timeextraction temperatureseparation temperaturepressure.Conclusion： The optimum extraction conditions are as follows： extraction temperature is 45℃,separation temperature is 55℃,the extraction pressure is 350 Bar,extraction time is 3.5 h.Under these conditions,the extraction rate of nucleolus oil from myrica rubra is 17.60%.
