Description
A salted fish fermentation that yields a liquid umami condiment used throughout the Roman Empire.
Technical
During the months‑long fermentation, endogenous fish proteases and halophilic microbes hydrolyze proteins into free amino acids, notably glutamic acid, which imparts intense umami. Concurrent lipolysis releases fatty acids and volatile phenols such as 4‑ethylphenol and 4‑ethylguaiacol, shaping the characteristic aroma. The process proceeds largely anaerobically, with pH dropping to ~4.5–5.0 as acids accumulate.
