Abstract: Astract:【Objective】The extraction conditions of residual Tung oil from cold pressing Tung meal by ultrasonic assistance were optimized.【Methods】Response surface analysis and simulation as a tool for design(Box-behnken)and optimization,and then quadratic multinomial mathematical model was established to optimize the process conditions of ultrasonic assisted extrac-tion for residual Tung oil.Finally,the effects of four main factors were studied,such as ratio of liquid to solid,extraction temperature,extraction time and ultrasonic power.【Results】Through response surface analysis and simulation,the optimized conditions for extraction of residual Tung oil assisted by ultrasound were listed as follows:the extraction time of 24.77 min,the extraction temperature at 37.18℃,ultrasonic power of159.66 W,liquid to solid ratio in 3∶1(mL/g),where the predictive yield was 6.30%.The validation experiment showed that the actual yield was(6.45±0.2)%.HPLC analysis showed that the ultrasonic assisted extraction of tung oil was consistent with the traditional solvent extraction.【Conclusion】Experiment design using response surface method and statistical analysis can effectively optimize the process conditions of ultrasonic assisted extraction of residual oil from Tung meal and well predict the results,which further proves that Tung oil extracted by the ultrasonic assisted method can maintain a good quality.
