What You Need to Know
During drying, salt draws water out of muscle cells via osmosis, lowering water activity and creating an environment hostile to mesophilic bacteria. Protein denaturation occurs gradually at 0–10 °C, maintaining tenderness, while the limited moisture and temperature suppress Maillard browning. The resulting product is a lean, high‑energy food with minimal chemical changes.
