Flash freezing is a rapid thermal technique that brings food temperatures below -40 °C within seconds, minimizing ice crystal growth and preserving cellular integrity.
Origin: Japanese scientists (1950s) — Japan
See full technique reference →By using cryogenic agents such as liquid nitrogen or CO₂, flash freezing halts enzymatic activity and protein denaturation, extending shelf life while maintaining sensory quality. The rapid nucleation of ice crystals at high cooling rates prevents the formation of large crystals that would otherwise damage cell membranes.
