What You Need to Know
The NaCl in the brine disrupts protein–water interactions, increasing water retention, while sodium nitrite reacts with myoglobin to form nitrosyl heme complexes that stabilize color and inhibit Clostridium botulinum. The process also preserves enzymatic activity at 4–10 °C and prevents oxidation with additives such as sodium erythorbate.
The Science
Primary Reaction
Salt-induced protein solubilization and nitrite-mediated myoglobin oxidation to nitrosyl heme
