Frozen food

frozenfrozen foodsfreezing
Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food).
In the food commodity industry, there are two processes: mechanical and cryogenic (or flash freezing).

Dry ice

This rapid freezing is done by submerging the sample in liquid nitrogen or a mixture of dry ice and ethanol.
Dry ice can be used to flash-freeze food or laboratory biological samples, carbonate beverages, make ice cream, solidify oil spills and stop ice sculptures and ice walls from melting.

American inventor Clarence Birdseye developed the "quick-freezing" process of food preservation in the 20th century.
That same year, he developed an entirely new process for commercially viable quick-freezing: packing fish in cartons, then freezing the contents between two refrigerated surfaces under pressure.
