| Abstract: | In this study,sorghum pigment is extracted from sorghum shell.Through ultrasonic pretreatment,single factor experiment and L9（34） orthogonal experiment methods are applied to investigate the effects of solid-liquid ratio,extraction temperature,extraction time,ethanol concentration on the rate of sorghum pigment extraction.The optimal conditions are as follows： ultrasonic frequency 20-25 kHz,power100 W,time 30 s,interval 10 s,the total output time 20min,solid-liquid ratio 1： 8,extraction temperature 60℃,extraction time 1 h,alcohol contraction 75%,the maximum extraction rate 15.36%,which is 6.83% higher than the traditional alcohol extraction. |
