Preparation of low phytate rapeseed protein by ultra filtration 2. membrane development and testing


, : Preparation of low phytate rapeseed protein by ultra filtration 2. membrane development and testing. Journal of the American Oil Chemists' Society 58(12): 1021-1023

The feasibility of using ultrafiltration (UF) to eliminate phytate from aqueous sodium chloride extracts of rapeseed was studied. With a proper choice of casting solution composition and casting conditions, high flux asymmetric cellulose acetate membranes of different surface porosity capable of giving different levels of phytate-protein separation were effectively created. The efficiency of the cast cellulose acetate membranes on phytate-protein separation was greatly influenced by the solution pH. The presence of sodium chloride in the processed solution was important to obtain a low retention of phytate. Complete removal of phytate from rapeseed extract with little or no loss of proteins was achieved using continuous diafiltration.
