What You Need to Know
The method relies on controlled combustion at 120–150 °C, where collagen hydrolyzes to gelatin at 60–70 °C while the surface remains below 200 °C to suppress Maillard browning. Phenolic smoke compounds such as guaiacol and syringol act as natural antioxidants, reducing lipid oxidation and extending shelf life.
