Abstract:
1. A method for producing a yeast extract containing a peptide selected from the group consisting of γ-Glu-X and γ-Glu-X-Gly, which comprises culturing a yeast in a medium containing a peptide selected from the group consisting of γ-Glu-X, γ-Glu-X-Gly and X-Gly, and preparing a yeast extract from the obtained cells, wherein X of the γ-Glu-X represents an amino acid or an amino acid derivative selected from the group consisting of Val, Ile, Ser, Thr, Met, Asn, Gln, Pro, Asp, Lys, Arg, His, Phe, Tyr, Trp, and derivatives thereof, wherein X of the γ-Glu-X-Gly represents an amino acid or an amino acid derivative other than Cys and derivatives thereof.
