Description
Controlled anaerobic fermentation of fish proteins by endogenous enzymes and halophilic bacteria produces savory amino acids and nucleotides.
Technical
Proteolytic enzymes (trypsin, chymotrypsin) hydrolyze fish muscle proteins into free amino acids (glutamate, aspartate) and peptides, while microbial action generates nucleotides (inosine monophosphate) through ATP degradation.
Culinary Significance
Creates a potent umami source that enhances flavor complexity in sauces, soups, and marinades across multiple cuisines.
