Description
A method of preserving meat by storing it at extremely low temperatures to slow enzymatic activity and microbial growth.
Technical
At temperatures below −40 °C, water in the meat forms smaller ice crystals, reducing cellular damage and preserving tenderness. Cryoprotectants such as glycerol or trehalose can be added to further inhibit ice‑crystal growth and protect protein structure. The resulting slow biochemical changes enhance flavor development while maintaining safety.
