Cryogenic freezing is generally considered a relatively expensive process. However, various new applications are constantly being discovered due to liquid nitrogen's unique ability to rapidly reduce temperatures to preserve the taste, texture and appearance of food products.

Freezing preserves the quality of the product because the ice forms microcrystals that do not damage the cells. Through this process, individual pieces freeze instantly and form a layer of ice or ice shell on the outside of the product to prevent drying and sticking.
