Abstract: 1. A PROCESS FOR RECOVERING PROTEIN FROM A PROTEINCONTAINING SOURCE MATERIAL OF VEGETABLE OR MICROBIAL ORIGIN WHICH COMPRISES FORMING AT A PH OTHER THAN THE ISOELECTRIC PH OF THE PROTEIN AN AQUEOUS SLURRY OF SAID PROTEIN SOURCE MATERIAL RAPIDLY HEATING SAID SLURRY UNDER PRESSURE TO AND HOLDING AT A TEMPERAURE IN THE RANGE FROM ABOUT 250 TO 350*F. FOR A PERIOD OF NOT MORE THAN SIX MINUTES, FLASH COOLING THE HEATED SLURRY UNDER REDUCED PREESSURE TO ACCOMPLISH SEPARATION OF VAPOR THEREFROM, AND RECOVERING THE COOLED HOMOGENEOUS SLURRY CONTAINING PROTEIN IN SOLUTION.
