摘　　要：利用超临界CO2对石榴籽中石榴籽油的萃取进行了研究,研究了粉碎度、装料量、萃取压力、萃取温度、CO2流量、分离压力和分离温度对石榴籽油萃取率的影响。试验表明,超临界CO2萃取石榴籽油的工艺参数是粉碎度40目、装料量200g、萃取压力30MPa、萃取温度40℃、CO2流量15L/h、分离压力8MPa、分离温度35℃,萃取率23.55%。The extraction of pomegranate seed oil from pomegranate seed with supercritical CO2 was investigated. Studied the influence of the degree of pulverization, feeds the quantity, the extraction pressure, the extraction temperature, CO2 flow rate, the separation pressure and the separation temperature to the pomegranate seed oil extractive speed. The experiment indicated that the optimum extracting conditions of supercritical CO2 extraction are degree of pulverization 40 item, feeds the quantity 200g, extraction pressure 30MPa, extraction temperature 40℃, CO2 flow rate 15L/h, separation pressure 8MPa and separation temperature 35℃, extractive speed 23.55%.
