Product description:

Sodium Benzoate (E211) is a sodium salt of benzoic acid, a compound naturally present in small concentrations in foods like prunes, cranberries, cinnamon, cloves, and apples. In its commercial form, E211 appears as a fine white powder with no odor or a faint almond-like scent (benzaldehyde).

Mechanism of Action

Sodium benzoate works by reducing the activity of key microbial enzymes, particularly those involved in the breakdown of fats and starches, and affecting oxidation-reduction processes. It also effectively inhibits the growth of yeasts and molds, extending the shelf life of a wide range of products.

• Mayonnaise, ketchup, margarine

• Jams, marmalades, fruit pastes

• Confectionery and baked goods

• Canned fish and caviar

• Meat products

• Pharmaceuticals – as a preservative in liquid medications

• Cosmetics and personal care – in shampoos, gels, toothpastes

• Aerospace industry – for protecting aluminum components and galvanized surfaces

• Pyrotechnics – to produce distinct sound effects in fireworks
