Description
Preserving with lard involves rendering fat to a solid, low‑water product that submerges meats, creating an oxygen‑free barrier that inhibits bacterial growth.
Technical
Lard is rich in saturated fatty acids (~40 %) with a melting point around 41 °C, allowing it to stay solid at refrigeration temperatures. During rendering, water is expelled and triglycerides are heated, forming a stable fat that can encapsulate meat. The solidified fat blocks moisture and oxygen, while the low water activity suppresses aerobic microbes.
Science
Primary Reaction
rendering of lard (dehydration and melting of triglycerides) and submersion of meat in fat creates an anaerobic environment
