What You Need to Know
During fermentation, proteolytic enzymes and microbial communities hydrolyze fish proteins into amino acids, peptides, and ammonia, while the brine’s pH drops and volatile sulfur, aldehyde, and ketone compounds develop, creating a complex umami profile. Salt concentration modulates microbial growth, preserving the product while allowing enzymatic activity to proceed.
