Description
Curing and dry‑aging are advanced preservation techniques that use salt, nitrite, temperature, and humidity to inhibit microbial growth while inducing enzymatic, Maillard, and color‑forming reactions that develop flavor, texture, and appearance.
Technical
During curing, a salt concentration of 2–3 % (w/w) lowers water activity below 0.85, and sodium nitrite (0.1–0.3 % w/w) reacts with myoglobin to form nitrosylmyoglobin, giving cured meats their characteristic pink color and developing flavor over 48–72 h at 4 °C. In dry‑aging, endogenous proteases such as plasmin and cathepsins cleave myofibrillar proteins at 0–4 °C and 80–85 % RH, tenderizing the meat by up to 30 % while the Maillard reaction at 60–70 °C generates brown pigments and complex flavor compounds.
