Abstract
Abstract A soy protein having excellent water-solubility, gel-forming ability, water-binding property and emulsifying property is obtained by separating the protein at a temperature below 80* C. in an acidic condition from soy milk which is obtained from soybean meal or soybeans by water extraction, alkalizing the protein with an alkalizing agent, returning the pH to about neutral with acid and thereafter heating the resulting protein solution at a temperature above 60* C.
