What You Need to Know
Proteolytic enzymes from halophilic bacteria hydrolyze fish proteins into free amino acids, peptides, and glutamates, creating a rich umami profile. The fermentation also generates biogenic amines such as histamine and tyramine, as well as volatile sulfur compounds that contribute to the complex aroma and flavor of the sauce.
