A PROCESS FOR PREPARING A BLAND, OPTICALLY CLEAR, HEAT GELABLE SOYBEAN PROTEIN WHICH COMPRISES ADDING ONE PART BY WEIGHT OF SOYBEAN MEAL TO 2 TO 100 PARTS BY WEIGHT OF WATER, HAVING A PH OF 3.5 TO 5.5, TO FORM A FIRST SLURRY, MAINTAINING THE PH OF SAID FIRST SLURRY AT 3.5 TO 5.5 DURING SAID ADDITION, MAINTAINING THE TEMPERATURE OF SAID FIRST SLURRY BELOW ABOUT 40*C. TO OBTAIN A SOLUBLE FRACTION CONTAINING SOLUBLE PROTEIN, SOLUBLE CARBOHYDRATES AND SOLUBLE SALTS AND AN INSOLUBLE FRACTION CONTAINING INSOLUBLE PROTEIN, CELLULOSIC CONSTITUENTS AND INSOLUBLE SALTS, SEPARATING SAID SOLUBLE FRACTION FROM SAID INSOLUBLE FRACTION, SUSPENDING SAID INSOLUBLE FRACTION IN WATER TO FORM A SECOND SLURRY, ADJUSTING THE PH OF SAID SECOND SLURRY TO 6 TO 8 TO SOLUBILIZE THE PROTEIN INSOLUBLE IN SAID FIRST SLURRY, SEPARATING SAID SECOND SLURRY INTO A SOLUBLE FRACTION CONTAINING SAID SOLUBILIZED PROTEIN AND AN INSOLUBLE FRACTION CONTAINING CELLULOSIC MATERIALS AND INSOLUBLE SALTS, ADJUSTING THE PH OF SOLID SOLUBLE FRACTION OF SAID SECOND SLURRY TO THE ISOELECTRIC POINT OF SAID SOLUBILIZED PROTEIN WITH ACID WHILE AVOIDING LOCAL CONCENTRATION OF ACID, THEREBY PRECIPITATING SAID SOLUBILIZED PROTEIN, AND SEPARATING SAID PRECIPITATED PROTEIN.
