In different countries, with different climatic conditions and feeding habits always valued long-term storage methods, the most effective of which was considered freezing. Often used for this purpose a block of ice, which were cut down in the winter on the rivers or man-soaked hills and evolved into the deep cellars. This ice did not melt even in summer, serving as a kind of precursor of the modern refrigerator.
Currently saving products by different freezing methods are widely used all over the world, and even in America celebrated the National Day of frozen food (National Frozen Food Day). He is celebrated annually on March 6 — on this day in 1930 in Springfield (USA) first began selling frozen food. A revolution in the food industry has made Clarence Birdseye (Clarence Birdseye). According to reports, the idea of ??applying the methods of freezing food came to him while traveling by dog ??sled on the Canadian Labrador peninsula.
