Anthony Rossi who founded Tropicana Products in 1945 was an Italian immigrant who arrived in the US with $25 and did not know English. He developed an orange juice pasteurization process to allow transport from the factory in Florida to as far away as New York starting in 1970.
Major orange juice producers add chemical fragrances called “flavor packs” to their juice to provide the signature taste of their brand because orange juice loses its flavor during pasteurization and de-oxygenation. The formulas vary to give a brand’s trademark taste. If you’re discerning you may have noticed Minute Maid has a candy like orange flavor. That’s largely due to the flavor pack Coca-Cola has chosen for it. Some companies have even been known to request a flavor pack that mimics the taste of a popular competitor, creating a “hall of mirrors” of flavor packs. Despite the multiple interpretations of a freshly squeezed orange on the market, most flavor packs have a shared source of inspiration: a Florida Valencia orange in spring.
Tropicana OJ is owned by Pepsico and Simply Orange by Coca Cola. They strip the juice of oxygen for better storage, which strips the flavor. They then hire flavor and fragrance companies, who also formulate perfumes for Dior, to engineer flavor packs to add to the juice to make it “fresh.”
