OJ was just a seasonal treat until WWII, when the government charged the Florida Citrus Commission with finding a way to ship vitamin C-packed juice overseas to prevent scurvy among the troops. Their solution, frozen concentrate, was literally created in a vacuum---and gave rise to a major new U.S. industry. By the war’s end, reconstituted juice had reached the front lines. And by the 1950s, housewives across the country were stirring up OJ for breakfast year-round.
