Orange juice is the liquid extract of the fruit of the orange tree, produced by squeezing oranges. It comes in several different varieties, including blood orange, navel oranges, valencia orange, clementine, and tangerine. As well as variations in oranges used, some varieties include differing amounts of juice vesicles, known as "pulp" in American English, and "juicy bits" in British English. These vesicles contain the juice of the orange and can be left in or removed during the manufacturing process. How juicy these vesicles are depend upon many factors, such as species, variety, and season. In American English, the beverage name is often abbreviated as "OJ".
Due to the importance of oranges to the economy of the state of Florida, "the juice obtained from mature oranges of the species Citrus sinensis and hybrids thereof" was adopted as the official beverage of Florida in 1967. Orange juice (along with grapefruit juice) is offered to every visitor at each of the state's five Florida Welcome Centers. Commercial orange juice with a long shelf life is made by drying and later rehydrating the juice, or by concentrating the juice and later adding water to the concentrate. Prior to drying, the juice may also be pasteurized and oxygen removed from it, necessitating the later addition of a flavor pack, generally made from orange products.
