Abstract: The acid hydrolysis of soybean isoflavone sugar-moiety to produce a new soybean isoflavone containing low sugar and high activity daidzin was studied.The optimal reaction conditions of the acid hydrolysis of soybean isoflavone were:0.1mol/L hydrochloric acid for 3 hours,temperature 40℃and the ratio of hydrochloric acid and sample 5∶1.Genistein content was 5.95% and the ratio of break 5.25%.

Key words: Soybean isoflavone , Genistein , Acid hydrolysis
