What You Need to Know
High‑salt brines lower water activity (a_w) below 0.85, while acetic acid reduces pH to ≤4.3, suppressing pathogenic and spoilage bacteria. Honey provides an osmotic environment (a_w≈0.6) and smoke deposits phenolic compounds that act as antioxidants and antimicrobials. Olive oil seals create anaerobic conditions and its phenolics further retard lipid oxidation.
The Science
Primary Reaction
Osmotic dehydration and acidification combined with phenolic antimicrobial action
