Precise low‑temperature cooking in vacuum preserves protein structure and moisture while preventing oxidation.
Origin: French chefs (1970s) — France
See full technique reference →At 55–65 °C the myosin denatures selectively while actin remains native, limiting gel formation. Vacuum sealing removes oxygen, suppressing lipid‑oxidation pathways that generate aldehydes and ketones. Added NaCl or phosphates increase ionic strength, enhancing myofibrillar water‑binding and reducing drip loss.
