Description
Sous‑vide protein gelation exploits controlled denaturation of myosin and collagen at 55–60 °C to form a stable, uniform protein network, achieving tenderness and juiciness unattainable with conventional high‑temperature methods.
Technical
Protein denaturation and subsequent gelation in sous‑vide occurs most efficiently at 55–60 °C, where myosin and collagen unfold and form a stable network; temperatures above 70 °C accelerate over‑cooking, causing a rubbery texture and loss of gel strength. The gelation process is governed by the unfolding of protein secondary structures (α‑helices to random coils) and the subsequent formation of intermolecular disulfide bonds and hydrogen bonds, which stabilize the matrix.
