Abstract:

Nine fractions were obtained by Sephadex G-15 gel filtration chromatography from enzymolyzed Parma ham. G-15-P2-E2 was identified to be a flavor peptide through sensory evaluation analysis and electronic tongue determination. G-15-P2-E2-r1 and G-15-P2-E2-r2 were obtained by semi-preparative RP-HPLC chromatography. Through MS/MS analysis, the amino acid sequence of G-15-P2-E2-r1 was Leu-Ser-Glu-Arg-Tyr-Pro (LSERYP, LP6) or Asn-Gly-Lys-Glu-Thr (NGKET, NT5), and that of G-15-P2-E2-r2 Pro-Asp-Leu-Pro-Asn-Thr (PDLPNT, PT6). Moreover, Leu-Ser-Glu-Arg-Tyr-Pro exhibited flavor properties similar to those of enzymolyzed Parma ham.
