| Abstract: | Applied dye yam as raw material,through the single factor test and orthogonal test,the ultrasonic assisted extraction of pigment dye yam ethanol process conditions were optimized.The test results showed that when dye yam sample preliminary soak was 2h,ethanol concentration was 50%,and liquid-solid ratio was 1：40,ultrasonic power was 200W,extraction temperaure was 60℃,Extracted was 25 min,the extraction of pigment dye yam had best effect.The extraction technology was simple,efficient and had good repeatability. |
