Abstract:

A new technology for red raspberry seed oil extraction was proposed using ultrasonic-assisted organic solvent extraction method. The optimal extraction parameters were investigated using single factor method combined with orthogonal array design. Results revealed that the optimized values of extraction parameters were obtained as follows: ultrasonic power 100 W, ultrasonic treatment temperature 30 ℃, ultrasonic treatment time 25 min, and liquid/solid ratio 11:1 (mL/g). This optimization led to an oil yield of 12.97%.
