    en.wikipedia.org/wiki/Frozen_food

    Cryogenic freezing is the quickest freezing technology available due to the ultra low liquid nitrogen temperature −196 °C (−320 °F). [ 2 ] Preserving food in domestic kitchens during modern times is achieved using household freezers .

  3. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a vacuum pump. [2] Liquid nitrogen's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in an insulating layer of ...

  4. Plant cryopreservation - Wikipedia

    en.wikipedia.org/wiki/Plant_cryopreservation

    Plant cryopreservation is a genetic resource conservation strategy that allows plant material, such as seeds, pollen, shoot tips or dormant buds to be stored indefinitely in liquid nitrogen. [1] After thawing, these genetic resources can be regenerated into plants and used on the field.

    en.wikipedia.org/wiki/Flash_freezing

    The freezing from the surface or from within may be random. [11] However, in the strange world of water, tiny amounts of liquid water are theoretically still present, even as temperatures go below −48 °C (−54 °F) and almost all the water has turned solid, either into crystalline ice or amorphous water.

  6. Freezing - Wikipedia

    en.wikipedia.org/wiki/Freezing

    Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. [ 1 ] [ 2 ] For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures.

  9. Individual quick freezing - Wikipedia

    en.wikipedia.org/wiki/Individual_Quick_Freezing

    Cryogenic IQF freezers immerse the product in liquid nitrogen at very low temperatures, freezing it rapidly while continuously moving the product to avoid block or lump formation. [5] Although this method shows good freezing results, it might lead to higher processing costs per weight of product due to the cost of the liquid nitrogen required.
