Description
Controlled pyrolysis of fermented shrimp proteins releases volatile sulfur compounds that enhance umami perception.
Technical
Maillard reactions between shrimp-derived amino acids and reducing sugars occur alongside lipid oxidation, producing pyrazines (2-ethyl-3,5-dimethylpyrazine) and sulfur-containing compounds (dimethyl trisulfide). The low-moisture environment prevents hydrolysis while promoting non-enzymatic browning.
Culinary Significance
Transforms the pungent raw belacan into a complex aromatic base that binds oil-soluble flavors into rempah pastes.
