Of course, frozen food has always existed in climates that were cold enough for the food to freeze. Many people developed innovative food-freezing techniques, including Enoch Piper, William Davis, and Daniel E. Somes. However, Clarence Birdseye is credited with inventing in 1924 the quick freezing method, which produces the type of frozen foods that we know today.
While working as a fur trader in Labrador, NF, Canada, Birdseye discovered that the fish that he and the local Inuit caught froze almost immediately after being pulled from the water. He was delighted to discover that the fish was just as delicious when thawed out months later. From this experience, he theorized that food must be frozen very quickly in order for it to retain its taste and texture.
Birdseye was right. Before quick-freezing came along, foods were frozen at a fairly slow rate. This caused large ice crystals to form, which ruptured the cell membranes of the food. When the food was defrosted, the ice crystals melted and water would leak out, taking with it the food's flavor and texture.
Birdseye developed two methods for quick freezing foods, both of which employed the innovation of packaging the food beforehand.In the first technique, the package was held between two metal belts that were chilled to -40°F to -45°F using a calcium chloride solution.
In the second and more popular technique, the packaged food was held under pressure between two hollow metal plates that were chilled to -25°F by the evaporation of ammonia. Using this method, a two-inch-thick package of meat could be frozen to 0F in about 90 minutes, while fruits and vegetables took about 30 minutes.
Birdseye's quick-freezing process actually ended up creating 168 patents! These covered not only the freezing technique but also the packaging, type of paper used, and related innovations.
Clarence Birdseye invented frozen food in New York (USA) in 1949
Probably that the people who fought in the war, they didn't have that much access to heat than us so the probably used the frozen foods and out them in the microwave and maybe ate them. And I think that's why can food was invented, for the war.
yes they are they will eat you and kill you
eggs
so it stays fresh
