Calcium benzoate refers to the calcium salt of benzoic acid. When used in the food industry as a preservative, its E number is E213 (INS number 213); it is approved for use as a food additive in the EU,[1] USA and Australia and New Zealand.[2]
The formulas and structures of calcium carboxylate derivatives of calcium and related metals are complex. Generally the coordination number is eight and the carboxylates form Ca-O bonds. Another variable is the degree of hydration.[3]
It is preferentially used more than other benzoic acid salts or it's esters in foods due to its better solubility and safety to humans.
