<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 provide a process for producing the same and the acidic foods with the use of the same. <P>SOLUTION: A solution containing soymilk is subjected to a treatment for eliminating or inactivating polyanionic substances contained therein and/or adding a polycationic substance and then heated at 100°C or above under acidic conditions. Thus, a soybean protein having a high solubility under acidic conditions and thus being appropriately usable in the acidic foods can be obtained. By use of this protein, protein foods in an acidic region can be provided. By combination of the above-described treatment with a protease-digestion treatment, a soybean protein hydrolyzate having a high solubility in the acidic region can be efficiently obtained. <P>COPYRIGHT: (C)2009,JPO&INPIT |
