What You Need to Know
The process relies on the volatilization of α‑pinene, terpinen‑4‑ol, and limonene between 70–90 °C, which infuse the meat with piney, resinous aromas. At temperatures above 120 °C the terpenes polymerize, producing bitter off‑flavors, while insufficient airflow (<10 L min⁻¹) leads to incomplete combustion and the formation of polycyclic aromatic hydrocarbons.
The Science
Primary Reaction
Volatilization of juniper essential oils and controlled oxidation of meat proteins
