Ag. vegetable protein disperslons are subjected to successive pressure and cavitation cycling at temps. below the denaturation point and at pH 7-8 to give products with high N soly. index. Thus, 1000 parts soybean protein conc., 7000 parts H2O, and 6 parts NaOH were slurried and pumped at 18.9L/min to a centrifugal homogenizer operating at 6150 rpm, 0.9 mm clearance, discharge pipe back pressure -2.1 kg/cm2, steam injection at 1.4-2.8 kg/cm2, and 104≦̸ temp. The discharged product was neutralized to pH 6.4 at 71≦̸C with 10N HCl, and pumped to a concurrent-flow spray drier operating with air inlet and outlet temps. of 210-25 and 92-8≦̸.
