| Abstract: | The best condition of extracted isoflavone of the fermentation soybean milk with ultrasonic wave was studied in this paper, the optimal conditions for extracted soybean isoflavone-glycosidase were determined by the single factor and orthogonal test experiment. The results showed that the optimal condition was the ethanol concentration 90%, 60 ℃, extraction for 45 min. Under the best reaction condition, the content of soybean iso-flavone-glycosidase was 134.41 μg·mL-1 analyzed by HPLC. |
