What You Need to Know
Rapid cooling at –196 °C or higher rates (>10 000 °C/min) limits ice crystal nucleation and growth, thereby preventing cellular rupture. The process also suppresses enzymatic activity and lipid oxidation, maintaining protein structure and flavor compounds. Controlled storage at –80 °C for months preserves the frozen state without recrystallization.
The Science
Primary Reaction
Rapid freezing reduces ice crystal growth, preserving cellular structure and protein integrity
