Description
Ancient Greek and Roman fish sauce was a halophilic fermentation of small fish in salted vats, producing a salty, umami condiment traded across the Mediterranean.
Technical
The process relied on proteolytic enzymes and halophilic bacteria to hydrolyze fish proteins into amino acids, peptides, and volatile esters. The resulting liquid contained high levels of glutamic acid, tyramine, histamine, and characteristic esters such as 3‑methyl‑2‑butenyl‑1‑yl acetate, giving it a pungent, umami-rich aroma.
