What You Need to Know
By maintaining temperatures between 55 °C and 70 °C for extended periods, the method allows controlled unfolding of myosin and collagen, preventing over‑cooking while suppressing Maillard browning. The vacuum environment reduces oxidation and limits microbial growth, and the slow heat transfer ensures even temperature distribution throughout the food matrix.
