What You Need to Know
Cold smoking induces mild protein denaturation and lipid oxidation, allowing phenolic smoke compounds such as guaiacol and syringol to diffuse into the fish. These phenolics contribute antioxidant activity and characteristic smoky flavor, while controlled temperature and time prevent excessive Maillard reactions and polycyclic aromatic hydrocarbon (PAH) formation.
The Science
Primary Reaction
Cold smoking causes protein denaturation and lipid oxidation while phenolic compounds from hickory smoke diffuse into fish tissue, forming flavor and antioxidant compounds.
