Processed cheese, process cheese, cheese slice, prepared cheese, cheese singles or cheese food is a food product made from normal cheese and sometimes other unfermented dairy ingredients, plus emulsifiers, extra salt, food colorings, or whey. Many flavors, colors, and textures of processed cheese exist.
In the United States, the most recognizable variety of processed cheese is sold under the name American cheese, although this name also has other meanings. American cheese is processed and usually bought sliced at a grocery store. The name American cheese also has a legal definition as a type of pasteurized processed cheese under the U.S. Code of Federal Regulations.[1]
Although processed cheese was first invented in 1911 by Walter Gerber of Thun, Switzerland, it was James L. Kraft who first applied for an American patent for his method in 1916.[2][3] Kraft Foods also created the first commercially available sliced processed cheese, which was introduced in 1950. This form of sliced cheese and its derivatives have become commonplace in the United States, most notably used for cheeseburgers and grilled cheese sandwiches. The Laughing Cow is an example of European processed cheese.
