Acidic food and beverage like Fruit Juice ( Citric Acid ), sparkling drinks ( Carbon Dioxide ), Soft Drinks ( Phosphoric Acid ), Pickles ( Vinegar ) or other acidified food are preserved with potassium benzoate. It is approved for use in most countries including Canada , the U.S. , and the EU , where it is designated by the E Number E212. In the EU, it is not recommended for consumption by children. {Link without Title} Cats have a significantly lower tolerance against benzoic acid and its Salts than Rats and Mice . {Link without Title} This compound was humorously referred to in an episode of The Simpsons as an ingredient of toppings for frozen yogurt, otherwise known as " Frogurt ". MECHANISM OF FOOD PRESERVATION The mechanism starts with the absorption of benzoic acid in to the cell. If the intra cellular PKa changes to 5 or lower the Anaerobic Fermentation of Glucose through phosphorfructokinase is decreased by 95%. {Link without Title} SAFETY AND HEALTH In combination with Ascorbic Acid (vitamin C), sodium (and potassium) benzoate can form Cancer -causing Benzene . Heat, light and shelf life can affect the rate benzene is formed. The FDA is currently (as of March 2006) performing tests, but the Environmental Working Group is calling for warning labels and a ban in schools. [http://www.ewg.org/news/story.php?id=5134 .
