What You Need to Know
Cryogenic freezing involves the rapid cooling of a substance to extremely low temperatures, typically below -196°C, using liquid nitrogen as the cooling agent, which can cause the formation of ice crystals, affecting the texture and structure of the frozen substance. This process requires specialized equipment and training to perform safely.
