摘　　要：采用正交设计法，在超临界c02流体萃取装置上探索了萃取温度（50～70oC）、萃取压力（18～26MPa）、萃取时间（1～3h）以及原料装填量（160—240g）对葡萄籽油萃取率的影响。萃取压力影响最大，其次为萃取温度和时间，原料装填量影响最小。结果表明，优化的萃取工艺条件为：萃取温度50℃，萃取压力26MPa，萃取时间lh，葡萄籽装填量200g；此条件下，葡萄籽油的萃取率为11．23％。Using orthogonal design method, the extraction rate of grape seed - oil is investigated under a super - critical CO2 fluid extractor. The factors such as extraction temperature （ 50 ～ 70 ℃ ）, extraction pressure （ 18 - 26 MPa）, extraction time （ 1 - 3 h） and loading amount of raw material （ 160 - 240 g） af- fecting the extraction rate of grape seed - oil are determined. The extraction ratio that influenced by each factor is as follows： pressure, and temperature and time, and loading amount of raw material. The experi- mental results show that the optimization of processing conditions is temperature 50 ℃, pressure 26 MPa, time 1 h,loading amount 200 g. Under these conditions, the highest extraction ratio of grape seed - oil is 11.23 %.
