What You Need to Know
During cold smoking, phenolic compounds such as guaiacol and syringol penetrate the fish matrix and form covalent cross‑links with protein side chains, stabilizing structure and lowering water activity. Hot smoking induces a Maillard reaction between reducing sugars and amino groups, producing melanoidins and aromatic aldehydes that contribute to browning and antioxidant activity, while controlled temperatures limit nitrosamine formation.
