What You Need to Know
During smoking, phenolic compounds such as guaiacol and syringol, along with aldehydes, diffuse into the oil. The process must be kept below 100 °C to avoid oxidation of unsaturated fatty acids; exceeding 120 °C can produce trans‑fats and rancid off‑odors. Water contamination triggers hydrolysis, leading to off‑odors and loss of flavor.
The Science
Primary Reaction
mass transfer of smoke-derived phenolic and aldehyde compounds into oil
