Caramel Coloring in Soda: What You Should Know About This Innocent-Sounding Ingredient
by Michael F. Jacobson
One ingredient in a can of Coke or Pepsi I've never been concerned about is "caramel coloring." After all, wouldn't that just mean the drink was colored with the kind of caramel you could make at home, by melting and browning sugar in a pan?
The truth is more complicated. It turns out that federal regulations describe four types of caramel coloring. And at least three of them are quite different from the confection with the similar name. All of them do start out with some form of sugar. One is called plain caramel. A second involves reacting the sugar with sulfites. A third is made be reacting sugars with ammonium compounds. And in the fourth variety of caramel coloring--the kind used in Coke and Pepsi--sugars are reacted with both ammonium and sulfite compounds. Both the regulations and some manufacturers' Web sites call this form of caramel coloring Caramel IV, or less appetizingly, ammonia-sulfite process caramel.
