One of the main advantages of this method of preparing frozen food is that the freezing process takes only a few minutes. The exact time depends on the type of IQF freezer and the product. The short freezing prevents formation of large ice crystals in the product's cells, which destroys the membrane structures at the molecular level.
The Cells Alive System (CAS) is a line of commercial freezers manufactured by ABI Corporation, Ltd. of Chiba, Japan claimed to preserve food with greater freshness than ordinary freezing by using electromagnetic fields and mechanical vibrations to limit ice crystal formation that destroys food texture.
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 the fast-flowing air provides good heat transfer and therefore quicker freezing. Contact freezing uses physical contact other than air to transfer the heat.

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 ...
A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods. Cryoprotectants are also used to ...
Snap freezing (or cook-chill or blast freezing) is the process of rapid cooling of a substance for the purpose of preservation. It is widely used in the culinary and scientific industries. It is widely used in the culinary and scientific industries.
