What You Need to Know
The precise thermal regime denatures cell wall polysaccharides and inactivates enzymes such as polyphenol oxidase, preserving color, flavor, and nutrients. Heat below the denaturation point of key enzymes retains vitamin C and carotenoids, while vacuum sealing reduces oxidative browning. The controlled temperature and time also modulate texture from crisp to tender without over‑softening.
