What You Need to Know
The process relies on the adsorption of phenolic compounds such as guaiacol and syringol onto the fish surface, which inhibit bacterial growth. Brining reduces water activity to ~0.85, while controlled moisture loss during smoking further limits microbial proliferation. The charred wood also suppresses the formation of harmful smoke volatiles, extending shelf life in humid coastal environments.
