PROCESS FOR OBTAINING SOLID SOY ISOFLAVONE-CONTAINING PRODUCTS |
摘要 |
A process for obtaining a solid soy isoflavone- and protein-containing isolate in which isoflavones constitute at least 7% of the isolate and are present in predominantly glycoside form, (genistin + genistein) constitute at least 50% of the isoflavones, the weight ratio (genistin + genistein):(daidzin + daidzein) is at least 1.5:1 and the bulk density is at least 0.57 g/ml.The process includes the sequential steps of (a) heating a soy soluble extract (SSE), made by aqueous alcohol extraction of defatted soy solids and evaporation of the alcohol, at acid pH and at a temperature within the range 70 DEG -90 DEG C to cause sedimentation of an insoluble fraction containing saponin, trypsin inhibitor and isoflavone compounds; (b) cooling the mixture from step (a) to a temperature of not lower than 30 DEG C and separating the insoluble fraction from supernatant liquid in the mixture of step (a) at a temperature of not lower than 30 DEG C; and (c) drying the separated insoluble fraction in a drying system adapted to produce a bulk density of at least 0.57 g/ml in the solid isolate. |
