<P>PROBLEM TO BE SOLVED: To provide a beta-glucan peptide derivative having weak side effects and exhibiting excellent toxic substance-eliminating activity, and to provide a method for producing the beta-glucan peptide derivative. <P>SOLUTION: The beta-glucan peptide derivative having the weak side effects and exhibiting the excellent toxic substance-eliminating activity has an oxidation-reduction potential of from -1 mV to -500 mV, and exhibits the toxic substance-eliminating activity. The derivative has a tripeptide consisting of isoleucine, cysteine and cysteine ester-bonded to a hydroxy group of the beta-glucan. The derivative also has lactic acid ester-bonded thereto. The production method thereof includes a step for alkali-reducing a fermented liquid obtained by adding Monascus anka, Bacillus natto, baker's yeast and lactic acid bacteria to rice bran and soybean flour, and subjecting them to mixed fermentation, and has a fermentation step and a reducing step as main steps. <P>COPYRIGHT: (C)2009,JPO&INPIT |
