Then came dehydration — when liquid is sprayed into a chamber and blasted with hot air. The liquid evaporates, and the remaining solid, a dry particle, is left behind. The first industrial spray-dried dairy products were manufactured shortly after Kraft’s development of processed cheese in the 1920’s.
According to “The Fundamentals of Cheese Science,”dehydrated cheese products, which includes both cheese powders and dried, grated cheese, were developed for the U.S. Army as a means of preserving cheese solids under conditions which natural cheese would not normally be subjected.
The New Yorker points out that over time dehydrated cheese and packaged macaroni and cheese became staples during the course of the war.
Among the many companies producing cheese powders, a Danish processed-food company, Lactosan, claims that after one of its customers returned an order of processed cheese because he had nowhere to store it, a factory manager, Christian Jessen, began experimenting with melted cheese and industrial spray-driers, producing what we recognize as modern cheese powder in 1951.
