Description
Cryogenic encapsulation uses liquid nitrogen to freeze food so rapidly that ice crystals remain microscopic, preserving texture and cellular integrity.
Technical
The extreme cooling rate (~10^4 K/s) arrests enzymatic and microbial activity by driving water into a solid phase before it can form large crystals. This preserves proteins and fats in their native conformation, preventing denaturation and oxidation.
Science
Primary Reaction
Rapid freezing suppresses enzymatic activity and microbial metabolism by arresting biochemical reactions at sub‑zero temperatures.
