What You Need to Know
Salt creates an osmotic gradient that draws water out of the muscle fibers, lowering water activity below 0.6. Ambient heat (20–30 °C) induces protein denaturation, while occasional smoking above 60 °C triggers Maillard reactions that generate melanoidins and volatile flavor compounds. The combined dehydration and salt inhibition suppress microbial growth, allowing months‑long storage.
