What You Need to Know
During smoking, volatile phenolics such as guaiacol and syringol condense onto the food surface, forming a thin antimicrobial film that lowers pH and inhibits bacterial growth. The heat (70–200 °C) drives oxidation of these compounds and facilitates the transfer of flavor‑enhancing aldehydes and ketones, while maintaining moisture to prevent over‑drying.
