Description
Nuoc Mam is a fermented fish sauce produced by layering small fish with 20‑25 % salt and aging it at warm ambient temperatures for months.
Technical
During fermentation, halophilic bacteria hydrolyze fish muscle proteins into free amino acids, especially glutamate, which imparts a pronounced umami flavor. Prolonged aging also triggers Maillard‑like reactions that generate volatile pyrazines and aldehydes, contributing to the sauce’s complex aroma profile.
Science
Primary Reaction
Proteolysis of fish proteins by halophilic bacteria releasing free amino acids (notably glutamate).
