What You Need to Know
Lean meat is dehydrated to a moisture content below 20 % (a_w < 0.6), which suppresses bacterial growth by limiting water activity. Rendered animal fat is mixed in to create an oxygen‑impermeable matrix that further retards oxidation and spoilage. The low‑moisture environment minimizes Maillard reactions, preserving the original flavor while preventing rapid lipid oxidation.
