The popular Fireball Cinnamon Whiskey made headlines this week when Europeans banned it for containing too much propylene glycol, an ingredient found in antifreeze. But that’s not the only place it’s lurking.
Any flavor not found in nature—such as hot sauce–flavored pickles—was probably made possible by propylene glycol. The additive helps maintain consistency and taste in everything from paint to plastic to Pop-Tarts.
The FDA acknowledges that propylene glycol can cause kidney damage when consumed in large doses and skin irritation when it comes in direct contact with flesh. In the U.S., products can contain five grams of propylene glycol for every kilogram of body weight. European formulas, however, can only contain .1 gram per kilogram.
Here are other foods and beverages that contain propylene glycol, according to the Food Industries Manual and the Dow Chemical Company.
