When food is frozen, the water content inside it forms ice crystals. The process of freezing food involves reducing the temperature of the food to below freezing point, typically around 0°F (-18°C) or lower. As the temperature drops, the water molecules in the food begin to slow down and eventually solidify into ice crystals.
