""Tropicana orange juice is a pasteurized orange juice, and what they do is they store this juice, which is a full strength juice, in these million-gallon aseptic storage tanks for upwards of a year," Hamilton (that would be Alissa Hamilton, author of Squeezed: What You Don't Know About Orange Juice) told Calgary's Eyeopener. "And when the juice goes into the tanks, it's stripped of oxygen so it doesn't go bad in the tanks. However, when they strip the juice of the oxygen, they're also stripping it of the flavour-providing chemicals that are natural to the juice. So what companies such as Tropicana do is they hire flavour and fragrance companies, the same ones that make high-end perfumes and cologne, to engineer flavour packs to add back to the juice to make it taste fresh."
