Abstract:
Recently, gamma-glutamyl dipeptides (gamma-GPs) were found to be responsible for the attractive kokumi flavor of Parmesan cheese (PC). Quantitation of gamma-GPs and their parent amino acids in 13-, 24-, and 30-month ripened PC samples by LC-MS/MS and stable isotope dilution analysis (SIDA), in-cheese (13)C-labeling studies, followed by analysis of the gamma-glutamyl transferase (GGT) activity revealed gamma-GPs to be generated most efficiently after 24 months of ripening by a GGT-catalyzed trans...     »
