What You Need to Know
These methods rely on the physics of heat transfer, vacuum sealing, and phase changes to achieve consistent culinary results across diverse food matrices. Protein denaturation (e.g., myosin, actin, collagen) occurs at specific temperatures, while vacuum sealing limits oxygen‑mediated oxidation and rapid cooling induces protein aggregation or cross‑linking. Exposure to air after steaming triggers Maillard browning, altering flavor and color.
