What You Need to Know
Sous‑vide at 55–60 °C for 1–2 h achieves partial thermal inactivation of vegetative cells; subsequent HPP at 400–600 MPa for 5–60 min induces pressure‑driven denaturation of collagen and myoglobin, forming gelatin and stabilizing color. The synergistic effect reduces conventional cooking time and extends shelf life by inactivating spores and suppressing oxidation.
The Science
Primary Reaction
Thermal inactivation + pressure‑induced protein denaturation
