Soy protein concentrate is prepared by removing the sugar part and some food ingredients from defatted powder. Acid leaching and extraction with ethanol aqueous solution, in all these treatments, are initially insoluble, but partially dissolved and soluble, so it is possible to separate them by centrifugation. The main solubility and solubility are then dissolved in water, neutralized to pH 7.0 if necessary, and then dried to produce organic products. Most of the commercial capacity is made through aqueous extraction or acid leaching processes.
