  2. Freezing - Wikipedia

    en.wikipedia.org/wiki/Freezing

    Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacteria growth. Freezing is a widely used method of food preservation. Freezing generally preserves flavours, smell and nutritional ...

  3. Flash freezing - Wikipedia

    en.wikipedia.org/wiki/Flash_freezing

    The freezing speed directly influences the nucleation process and ice crystal size. A supercooled liquid will stay in a liquid state below the normal freezing point when it has little opportunity for nucleation; that is if it is pure enough and has a smooth enough container. Once agitated it will rapidly become a solid.

  4. Frozen food - Wikipedia

    en.wikipedia.org/wiki/Frozen_food

    Tunnel freezing is a variant of air-blast freezing where food is put onto trolley racks and sent into a tunnel where cold air is continuously circulated. Fluidized bed freezing is a variant of air-blast freezing where pelletized food is blown by fast-moving cold air from below, forming a fluidized bed. The small size of the food combined with ...

  5. Freeze drying - Wikipedia

    en.wikipedia.org/wiki/Freeze_drying

    Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process [1] that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. [2] This is in contrast to dehydration by most conventional methods that evaporate water using heat. [3]

    en.wikipedia.org/wiki/Individual_Quick_Freezing

    Individual quick freezing, usually abbreviated IQF, is a descriptive term for freezing methods used in the food processing industry. The food is in individual pieces, and is frozen quickly. The food is in individual pieces, and is frozen quickly.

  9. Fractional freezing - Wikipedia

    en.wikipedia.org/wiki/Fractional_freezing

    Fractional freezing is a process used in process engineering and chemistry to separate substances with different melting points. It can be done by partial melting of a solid, for example in zone refining of silicon or metals, or by partial crystallization of a liquid, as in freeze distillation, also called normal freezing or progressive freezing.
