Abstract
Abstract DISPERSED PLANT PROTEINS ARE DIGESTED WITH AN ACID ACTIVE ENZYME AT A PH BELOW 4.6. QUIESCENT CONDITIONS ARE MAINTAINED IN THE REACTION MEDIUM AND DIGESTION PROCEEDS UNTIL THE INSOLUBLE COLLOIDAL PROTEIN IS SUBSTANTIALLY COMPLETELY DISSOLVED. THE PH IS RSISED TO ABOUT 4.6. AND THE MEDIUM IS ALLOWED TO STAND CAUSING ADDITIONAL INSOLUBLE PROTEIN TO PRECIPITATE. THE INSOLUBLE RESIDUE IS REMOVED AND THE SOLUBLE POTEIN MATERIAL IS DRIED. A CLEAR LIQUID, WHICH CAN BE CARBONATED, IS FORMED CONTAINING THE SOLUBILIZED PROTEIN MATERIAL AT A PH CORRESPONDING TO THE ISOELECTRIC POINT OF THE PROTEIN.
