E213 – Calcium Benzoate

Description

Calcium benzoate is a calcium salt of benzoic acid, appearing as a white crystalline or powdery solid. It acts as a preservative by inhibiting the growth of molds, yeasts, and some bacteria, extending the shelf life of food products.

Notes

Calcium benzoate is produced by combining benzoic acid (which occurs naturally in fruits like cranberries and prunes) with calcium hydroxide, creating the calcium salt form of benzoic acid. This chemical reaction transforms the original benzoic acid into a compound that dissolves more readily in water and provides the added benefit of calcium content. The result is a white, crystalline powder that serves as both a preservative and a source of calcium. As a preservative, calcium benzoate prevents the growth of harmful bacteria, yeasts, and molds in food products, helping to extend shelf life and maintain food safety. You'll typically find it in processed foods, beverages, baked goods, and other packaged products where preservation is important. Food manufacturers sometimes choose calcium benzoate over sodium benzoate when they want to avoid adding sodium to their products or when they want to include calcium as an additional nutritional benefit. This synthetic preservative is suitable for vegetarians, vegans, and most religious dietary requirements. It can be particularly appealing to health-conscious consumers because it provides calcium – an essential mineral for bone health – while serving its preservative function. Like other benzoate preservatives, it's well-regulated and generally recognized as safe when used within approved limits, though some individuals may have sensitivities to benzoate compounds.
