| 摘 要： | 应用超临界CO2技术萃取莲子心油。研究了预处理条件(水分含量、粉碎度)、萃取条件(萃取温度与压力、CO2流量、时间)、分离条件(分离温度与压力)对莲子心出油率的影响;然后在单因素分析的基础上,进行正交试验,确定了超临界萃取的最佳工艺条件为:原料水分含量5%左右,粉碎度60目,CO2流量30L/h,时间2h,萃取压力32MPa,萃取温度50℃,分离压力9MPa,分离温度45℃,此时莲子心油的出油率为14.09%。

| Abstract: | The extraction of lotus germ oil by supercritical fluid CO2 has been studied. The influences of preprocessing conditions (moisture content, grind degrees), extraction conditions (temperature, pressure) and separation conditions (temperature, pressure) on the extraction rate were researched. On the basis of single factors tests, the optimal working parameters were worked out by orthogonal extraction tests: 5% of moisture content, 60 of grind degrees, 30L/h of CO2 of flow rate, 2 hours, 32MPa of extraction pressure, 50℃ of extraction temperature, 9MPa of separation pressure, 45℃ of separation temperature. |
