Processed cheese

Processed cheese is a dairy product. It is made from cheese. Other unfermented dairy products, emulsifiers, salts, food colorings and whey may be added to this. 

History
The first processed cheese was made by Walter Gerber in Thun, Switzerland in 1911. Today, this is still sold as Gala. The first processed cheese in Germany was made by Gebrüder Wiedemann, in 1922. This was named Adler (which is German for Eagle). At approximately the same time, Fromageries Bel launched La vache qui rit, which is still available today. In Austria, it was Alma, in 1921.

Advantages and disadvantages
There are a number of advantages of processed cheese over regular cheese. These are:
Processed cheese has a longer shelf-life
It is possible to use leftovers from other cheesemaking processes.
The melting process can be controlled better. Regular cheese often separates into fat, and proteins.
There are fewer flavors of processed cheese than of unprocessed cheese
One disadvantage to processed cheese is that it is unhealthier than other cheeses if eaten too much.
