<p><P>PROBLEM TO BE SOLVED: To solve a problem on recovery of a solvent when a flammable solvent is used and on an organic solvent remaining in extracted fractions, and to provide a method for producing industrially an acidic water-soluble protein made of wheat gluten as a raw material without being limited by conditions for shearing or devices for production such as a separation device. <P>SOLUTION: The method produces an acidic water-soluble protein by extracting a protein soluble in an acidic aqueous solution from wheat gluten. The acidic aqueous solution contains 1.5-3.0 wt.% of organic acid relative to the weight of dried wheat gluten. The organic acid contains at least lactic acid and malic acid, and the ratio in weight of the lactic acid to the malic acid is 83-18/17-82. The acidic aqueous solution does not contain a flammable solvent, and the acidic aqueous solution of 8-12 times as the weight of the dried wheat gluten is used. The pH of the acidic aqueous solution in which wheat gluten is dispersed is 3.7-4.3 when the protein is extracted. The problem is solved by the method for producing an acidic water-soluble protein. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
