Fake foods are used in many ways, such as props for backgrounds in movies, television shows, theatrical plays, television commercials, print ads and trade shows.
Fake foods are also used to display lifelike replicas of real foods for restaurants, grocery chains, museums, banquet halls, casino buffets, cruise ships and in many other instances in which real foods can not be displayed.
For instance, the American company Fake Foods began when fast food restaurant Wendy's needed fake kale for their salad bar display.
More recently, fake foods were also used for nutrition education and consumer research.

A specialized fiber utilized by NASA within the Space Shuttle program was manufactured at the Elizabethton plants during the 1980s, and after many years of a declining U.S. rayon market and increased foreign competition following the General Agreement on Tariffs and Trade and North American Free Trade Agreement, the remaining rayon mill (owned by the North American Rayon Corporation) closed down during the late 1990s.
