Abstract:
A process for producing a soy protein hydrolysate with a low content of .beta.-conglycinin, a glycinin and a trichloroacetic acid-soluble protein wherein a proteolytic enzyme is allowed to act on soybean protein which has been obtained without thermal denaturation from low-denatured de-fatted soybeans having a nitrogen solubility index of 60 or more, at a temperature of 60 to 80.degree. C. to selectively decompose .beta.-conglycinin in the soybean protein until the glycinin/.beta.-conglycinin ratio is 3.0 or more and the ratio of the trichloroacetic acid-soluble protein to whole protein (TCA ratio) is about 5 to 20%, and then raising the temperature enough to cease the enzyme reaction.
