Pop Rocks

Pop Rocks, also called popping candy, is a candy owned by Zeta Espacial S.A. Pop Rocks ingredients include sugar, lactose (milk sugar), and flavoring. It differs from typical hard candy in that pressurized carbon dioxide gas bubbles are embedded inside of the candy, creating a small popping reaction when it dissolves. Background and history The concept was patented by General Foods research chemists Leon T. Kremzner and William A. Mitchell on December 12, 1961 (U.S. patent #3,012,893), but the candy was not offered to the public until 1976, before General Foods withdrew it in 1983, citing its lack of success in the marketplace and its relatively short shelf life. Distribution was initially controlled to ensure freshness; but with its increasing popularity, unauthorized redistribution from market to market resulted in out-of-date product reaching consumers. After that, Kraft Foods licensed the Pop Rocks brand to Zeta Espacial S.A. which continued manufacturing the product under Kraft's license. Eventually, Zeta Espacial S.A. became the brand's owner and sole manufacturer. Pop Rocks is distributed in the U.S. by Pop Rocks Inc. (Atlanta, Georgia) and by Zeta Espacial S.A. (Barcelona, Spain) in the rest of the world. Zeta Espacial S.A. also sells popping candy internationally under other brands including Peta Zetas, Wiz Fizz, and Magic Gum. In 2008, Marvin J. Rudolph, who led the group assigned to bring Pop Rocks out of the laboratory and into the manufacturing plant, wrote a history of Pop Rocks development. The book, titled Pop Rocks: The Inside Story of America's Revolutionary Candy, was based on interviews with food technologists, engineers, marketing managers, and members of Billy Mitchell's family, along with the author's experience. In the book, Rudolph points out that the Turkish company HLEKS Popping Candy flooded the market with popping candy in the year 2000.
