Benzoic acid (E210) – what is it?
Benzoic acid (E210) is an organic chemical compound that belongs to the group of preservatives. It is a naturally occurring substance that can be found in some fruits and spices such as berries and cinnamon, but most of the benzoic acid used in industry is chemically synthesized.
As a food additive, benzoic acid is valued for its antibacterial and antifungal properties, making it an effective preservative to extend the shelf life of food products by preventing the growth of microorganisms.
Properties of benzoic acid
Benzoic acid is a colorless, crystalline substance, soluble in water and organic solvents such as alcohol and ether. It is characterized by a faint, characteristic odor and a bitter taste. Its preservative effect is most effective in an acidic environment (pH below 7).
Uses of benzoic acid
Benzoic acid is widely used as a preservative in many food products, including sodas, jams, jellies, bakery products and pickles. It is also used in cosmetics, pharmaceutical products and in the chemical industry as a raw material for other chemical compounds.
Where to buy benzoic acid?
Benzoic acid is available in chemical raw material stores, food stores and online. It can be purchased both in pure form and as an ingredient in ready-made preservative mixtures.
Benzoic acid and its functions in food
As a food additive, the main function of benzoic acid is to prevent the growth of bacteria, yeast and mold, which significantly extends the shelf life of food products and helps preserve their quality, taste, color and nutritional value. This is particularly important for products that are prone to rapid spoilage.
