A chewing gum with a liquid center is Freshen Up gum. Freshen Up was created in 1975 and was the first gum to have a liquid gel center.
Freshen Up chewing gum is available in peppermint, cinnamon, bubble gum and spearmint flavors. The product was originally processed in a Warner-Lambert assembly plant in Queens, N,Y. An explosion occurred on the manufacturing line in 1976, killing six of the factory workers. In 1977, the New York State Supreme dismissed manslaughter and homicide charges that had been brought against the company and its four executives. The Freshen Up brand is owned by Kraft Foods as of September 2014.
