What You Need to Know
Prolonged heating (~100 °C) hydrolyzes collagen to gelatin, softening connective tissue. Phenolic compounds from pine or mesquite wood diffuse into the meat, providing antioxidant smoke flavor. Fermented maguey sap lowers pH to ~5.5, inhibiting spoilage microbes while contributing subtle acidity.
