Abstract:
This paper studied the soybean isoflavones refining process by ultrafiltrating soybean meal extract with polyether sulphone organic membrane and then purified with D101 macroporous resin.The detailed soybean isoflavones refining process was studied and optimized conditions were obtained.The results showed that removal rate of the impurities was up to 56.1% by ultrafiltrating soybean ethanol extract with organic membrane of pore diameter 5 000 D.Purified by D101 macroporous resin,with 0.750 mg·mL-1 sample concentration and 1.0 BV·h-1 fluid samples rate,then successively rinsed with 1.0 BV deionized water,1.0 BV 10% ethanol and 2.0 BV 80% ethanol,purify of 41.2% soybean isoflavone products was obtained and the overall yield was 65.7%.
