Abstract
A low sodium, low monosodium glutamate soy hydrolysate is prepared from a soy material, as for instance, soy flour, soy meal or soy grits by hydrolyzing the soy material with a protease enzyme in water. The hydrolysis is conducted in the absence of the addition of either acid or base at a temperature of about 90.degree. for 2 hours. After deactivating the enzyme and dewatering the mixture the resulting hydrolysate contains from about 45 to about 55 weight percent of enzymatic hydrolyzed soy based protein, from about 1 to about 3 weight percent fat, from about 5 to about 9 weight percent ash, from about 2 to about 8 weight percent water, from about 32 to about 36 weight percent carbohydrate, and less than 0.1 weight percent sodium.
