<P>PROBLEM TO BE SOLVED: To provide a soybean protein material which is excellent in solubility, stability, emulsifying properties and gel-forming properties under acidic conditions and thus advantageously usable in acidic foods and to provide its production method, and to provide acidic foods using the soybean protein material. <P>SOLUTION: A solution containing soybean protein is subjected to treatment for eliminating or inactivating polyanionic substances contained therein and/or adding a polycationic substance and then heated at a temperature exceeding 100°C under acidic conditions. Thus, a soybean protein having a high solubility under acidic conditions and being appropriately usable in acidic foods can be obtained. By using the protein, protein foods in an acidic region can be provided. Further, by combining the above treatment with a protease-digestion treatment, a soybean protein hydrolysate having a high solubility in an acidic region can be efficiently produced. <P>COPYRIGHT: (C)2009,JPO&INPIT |
