Description
Vacuum‑sealed marination accelerates salt and flavor diffusion into protein tissues by eliminating air and enhancing mass transfer at low temperatures.
Technical
Under vacuum, the reduced pressure removes air pockets, allowing brine to penetrate meat up to 2–3 mm per hour at 4 °C—2–3× faster than conventional marination. The process relies on Fickian diffusion of NaCl and flavor molecules into protein matrices, while maintaining low temperatures to inhibit microbial growth. Acidic marinades (< pH 4.5) can cause rapid protein denaturation, softening delicate fish within minutes when combined with vacuum sealing.
