Description
Sous‑vide stews use low‑temperature, long‑time cooking (55–70 °C, 12–48 h) to gently hydrolyze collagen into gelatin while preserving protein structure, flavor, and nutrients.
Technical
At 55–65 °C collagen’s triple helix unwinds and hydrolyzes into gelatin, yielding a silky, tender matrix. Myosin denatures between 60–70 °C, causing muscle fibers to contract and release moisture, while fat melts around 55–60 °C, releasing flavor compounds without emulsifying. Precise temperature control prevents over‑gelatinization and maintains a desirable texture.
