Abstract
A defatted meal originating from oil-bearing seeds such as soybean, rapeseed or cottonseed is treated with an acidic aqueous solution to solubilize protein present in the meal. If desired any insoluble carbohydrates present can be removed. The pH of the resulting slurry or clarified solution is lowered to between 2.0 and 3.0 and maintained to dissociate the protein into its subunits. The slurry or clarified solution is heated to cause aggregation of the subunits and its pH is then raised prior to ultra-filtration. A membrane is employed which retains the proteinaceous material and yet allows salts and low molecular sugar to permeate.
