What You Need to Know
During the prolonged 200–250 °F (93–121 °C) cook, collagen hydrolyzes to gelatin around 160 °F (71 °C), while surface proteins denature and undergo Maillard reactions above 140 °F (60 °C), forming pyrazines and furans. Smoke from mesquite, oak, or pine deposits phenolic and heterocyclic compounds that contribute smoky aroma and mild antimicrobial effects, and nitrosylated heme pigments develop the deep reddish‑brown color.
