What You Need to Know
The smoke deposits phenolic compounds such as guaiacol and syringol, as well as acidic species that lower the surface pH to about 5.2. This acidification, combined with smoke‑induced dehydration, reduces water activity to ~0.85, creating a protective antimicrobial layer that extends shelf life while delivering a distinctive smoky flavor.
The Science
Primary Reaction
Deposition of smoke‑derived phenolics and acids onto cheese surface, altering pH and water activity.
