What You Need to Know
During cold smoking, phenolic compounds such as guaiacol and syringol generated from birch bark combustion diffuse into the meat and bind to myoglobin, stabilizing its red color and providing antioxidant protection. Smoke aldehydes (e.g., formaldehyde, acetaldehyde) react with surface proteins and lipids, forming cross‑links that inhibit microbial growth and slow oxidation. The low temperature prevents protein denaturation, maintaining tenderness while the smoke compounds act as antimicrobial agents.
