What You Need to Know
Rapid freezing at temperatures ≤–80 °C forms ice crystals that rupture cell membranes, while controlled thawing at 4–25 °C allows soluble peptides, amino acids, and volatile aromatics to diffuse into the aqueous phase. The process preserves aroma integrity by minimizing thermal degradation and sublimation.
