Description
Cold and hot smoking with native North American woods preserves protein foods by depositing smoke‑derived phenolics, acids, and carbonyls while controlling temperature to avoid protein denaturation.
Technical
During cold smoking (52‑80 °C) phenolic compounds such as guaiacol and syringol are deposited onto the meat surface, acting as antimicrobials by disrupting microbial membranes. Hot smoking (65‑95 °C) simultaneously cooks the meat and generates carbonyls and organic acids that lower pH, further inhibiting spoilage bacteria. Lignin pyrolysis in hardwood smoke produces aromatic phenols, while cellulose degradation yields acetic acid and formaldehyde, contributing to both flavor and preservation.
