超声波处理提取华山松籽油的研究

Study on the extraction of seed kernel oil of Pinus armandi via ultrasonic treatment

研究了超声波强度、处理时间、处理时溶剂用量、处理次数对华山松籽油提取率的影响,得出最佳处理条件为超声波强度200kW/m2,处理15min,样品与溶剂比(g∶mL)为1∶7,超声波处理2次,华山松籽油提取率较理想。

Seed kernel of Pinus armandi was processed by ultrasonic wave to enhance the extraction rate of pine nut oil.Effect of several factors (ultrasonic wave intensity,treatment time,solution ratio,extraction times) on ultrasonic wave processing was explored.The optimum conditions for processing were obtained.The results showed that it is under the conditions (ultrasound wave intensity 200 kW/m2,treatment time 15 min,solution ratio 1∶7 (g∶mL),treatment times 2) that extraction rate of pine nut oil was better.
