Description
Cryogenic freezing of sashimi uses liquid‑nitrogen temperatures to produce sub‑0.1 mm ice crystals, preserving cell structure and protein conformation.
Technical
Rapid cooling of water to form amorphous ice prevents ice crystal growth and minimizes protein denaturation. Enzymatic activity is halted below −40 °C, extending shelf life while maintaining freshness. The process preserves tertiary protein structure, yielding a smooth, firm texture characteristic of high‑quality sashimi.
