Description
Roman salt-curing used high-concentration brines at controlled ambient temperatures to preserve meats, fish, and vegetables by lowering water activity and denaturing proteins.
Technical
In a Roman brine, NaCl draws water out of tissues via osmosis, reducing the water activity (a_w) below 0.85 and thereby inhibiting bacterial growth. The high salt concentration also disrupts protein folding, causing denaturation and the formation of a gel-like matrix that further restricts microbial access. The process is enhanced by the addition of herbs and wine, which contribute antimicrobial compounds and flavor compounds that integrate into the protein matrix.
