Changes in the amino acid composition and contents of gamma-glutamyl-beta-alanyl-histidine isopeptide in the macromolecular fraction were measured during heating of chicken extract. Increases of histidine, 1-methylhistidine, and beta-alanine were observed, suggesting that carnosine and anserine were incorporated into the macromolecular fraction. The increase of gamma-glutamyl-beta-alanylhistidine isopeptide in the macromolecular fraction of chicken extract was also observed during the heating process. Furthermore, measurement of gamma-glutamyl-beta-alanylhistidine isopeptide in commercial chicken extract showed that all kinds of chicken extract contained the above isopeptide (from 0.09 to 0.31 micromol/g DM in the macromolecular fraction). These results suggest that the formation of gamma-glutamyl-beta-alanyl-histidine and related isopeptides occur during heating of chicken extract. |
