What You Need to Know
During smoking, volatile phenols such as guaiacol and syringol condense onto the food surface, forming a thin film that lowers pH and inhibits microbial growth. The process also generates aldehydes (acrolein, formaldehyde) and, at higher temperatures or prolonged exposure, polycyclic aromatic hydrocarbons that contribute to flavor and potential health concerns.
The Science
Primary Reaction
Condensation of phenolic and aldehydic compounds onto the food surface forming a protective film
