Abstract: In order to improve oil yield and quality, response surface methodology was employed to optimize the ultrasonic-assisted extraction of blackberry seed oil. A mathematical model was constructed describing oil yield as a function of temperature, extraction time, ultrasonic power and liquid (hexane)/material ratio. The optimal extraction conditions were obtained as follows: extraction temperature 42.82 ℃, extraction time 12.20 min, ultrasonic power 53.19 W, and ratio of solid to liquid 1:2.23. Under these conditions, the predicted oil yield was 12.6%, and the experimental value 12.5%.
