What You Need to Know
The process deposits phenolic compounds such as guaiacol and syringol onto the surface, forming a protective film that reduces water activity. The mild heat (65–80 °C) allows smoke penetration without cooking the product, and the phenolics react with surface proteins and lipids to create a stable, flavorful matrix.
The Science
Primary Reaction
Deposition of smoke phenolics onto the product surface and subsequent film formation that lowers water activity
