Description
Fermented fish preservation uses salt and temperature control to cultivate halophilic and lactic‑acid bacteria that break down proteins and lipids into flavor‑active compounds while suppressing pathogens.
Technical
Proteolysis and lipolysis by halophilic and lactic‑acid bacteria generate peptides, free amino acids such as glutamic acid, and volatile compounds like trimethylamine and aldehydes. Lactic acid and biogenic amines (e.g., histamine) develop under low‑pH conditions, while high salt concentrations favor halophilic Bacillus and lactic‑acid bacteria, producing a complex umami profile rich in glutamyl‑glutamic acid.
