The content of a kokumi peptide, γ-glutamyl-valyl-glycine (γ-Glu-Val-Gly), in several kinds of commercial fermented shrimp paste condiments was determined using a LC/MS/MS method after derivatization with 6-aminoquinoyl-N-hydroxy-succinimidyl-carbamate (AQC). Commercial fermented shrimp paste condiments from Indonesia (Terasi), the Philippines (Bagoong) and China (Xiajiang) were analyzed. The analyses revealed that the concentration of γ-Glu-Val-Gly in Terasi, Bagoong, and Xiajiang was 5.2 μg/g, 1.0 μg/g, and 0.9 μg/g, respectively. These results suggested that γ-Glu-Val-Gly is widely distributed in fermented shrimp paste condiments.
