Description
Vacuum‑sealed sous‑vide cooking preserves vegetable nutrients, color, and texture by precise temperature control and reduced oxygen exposure.
Technical
The process inactivates heat‑labile enzymes such as polyphenol oxidase and peroxidase while allowing starch gelatinization at temperatures between 55–80 °C. The vacuum environment limits oxidative reactions, reducing pigment degradation and nutrient leaching. Controlled heating also softens cell walls, yielding a tender yet crisp mouthfeel.
