Description
Coating foods with solidified lard creates an oxygen‑impermeable barrier that inhibits aerobic microbial growth, preserving meats, fruits, and vegetables for months when stored below 4 °C.
Technical
Lard is a mixture of triglycerides composed mainly of palmitic, stearic, oleic, and linoleic acids. The high saturated content (palmitic and stearic) provides a stable, solid matrix at ambient temperatures, while the unsaturated components (oleic and linoleic) are prone to oxidation, limiting shelf life. The solid fat layer physically blocks oxygen diffusion, thereby suppressing aerobic spoilage organisms.
