How is cola produced?
Jimmy Doherty reveals the secrets of cola in his food factory. He manages to recreate the taste of cola by using water, sugar, natural plant oils, gum arabic, caramel colouring, phosphoric acid and caffeine. He then experiments with frozen carbon dioxide to make his cola fizzy. He demonstrates what happens when he forces the carbon dioxide out of supermarket colas, as well as when frozen carbon dioxide is left in a sealed bottle with water.
