Potassium benzoate (E212) – what is it?
Potassium benzoate (E212) is the potassium salt of benzoic acid, a widely used food preservative. It is a white powder or granules, slightly soluble in cold water, which makes it ideal for food applications. Thanks to its antibacterial and antifungal properties, E212 effectively inhibits the growth of microorganisms that can lead to food spoilage and toxin production.
The substance has been approved for use in many countries as a safe food additive, reducing the risk of food poisoning and extending the shelf life of food products.
Properties of potassium benzoate
Potassium benzoate is valued for its ability to effectively inhibit the growth of bacteria, yeast and mold, especially in acidic environments (pH below 4.5). It is heat stable, meaning it can be used in heat-treated products without losing its effectiveness. In addition, it is less toxic than other preservatives, making it a preferred choice in food production.
Uses of potassium benzoate
E212 is widely used in the food industry, especially in products such as soft drinks, fruit juices, canned foods, fish products, sauces, jams and jellies. Its presence helps keep food fresh and safe by preventing it from spoiling quickly.
Where to buy potassium benzoate?
Potassium benzoate is available for purchase by food manufacturers, as well as small entrepreneurs and home cooks, mainly through chemical raw material distributors and specialty food additive stores. It can also be found in online stores that offer a wide range of food additives.
Potassium benzoate and its functions in food
As a preservative, potassium benzoate plays a key role in maintaining food quality and safety. It extends the shelf life of food products by inhibiting the growth of microorganisms that can cause spoilage. Its addition to foods also helps maintain flavor, aroma and textural qualities, which is important for consumer acceptance of a product. In addition, the use of E212 supports efforts to reduce food waste, which has a positive impact on the environment.
