What You Need to Know
The process combines gentle heat (30–60 °C) with phenolic antioxidants leached from banana leaves, which scavenge free radicals and form a protective film of phenol‑derived adducts on the fish surface. Simultaneously, smoke‑borne phenols, aldehydes and acrolein deposit, lowering water activity to ~0.70 and inhibiting microbial growth, thereby extending shelf life.

The Science
Primary Reaction
Phenolic adsorption and antioxidant activity during low‑temperature smoking reduces lipid oxidation and microbial proliferation.
