Description
Vacuum‑packaged freezing preserves protein foods by combining oxygen removal with rapid cooling to reduce ice crystal growth and oxidation.
Technical
By evacuating air, the process limits oxygen‑dependent lipid oxidation and enzymatic browning that normally occur during freezing. Rapid temperature drop under vacuum also restricts ice crystal nucleation and growth, yielding smaller crystals that preserve cell integrity and texture. The combined effect extends shelf life while maintaining flavor and safety.
