What You Need to Know
During low‑temperature smoking (70–80 °C), thujone and cineole from cedar bark volatilize and react with moisture to form phenolic compounds that coat the fish surface, lowering pH and inhibiting bacterial growth. The phenolic film also reduces oxygen penetration, slowing oxidative rancidity while preserving the fish’s raw texture.
The Science
Primary Reaction
Thermal volatilization and oxidation of cedar bark monoterpenes forming phenolic antimicrobial compounds
