Potassium hydrosulfite (E228) – what is it?
Potassium hydrogen sulfite, also known as E228, is a chemical compound used as a preservative in the food industry. Thanks to its antioxidant and antibacterial properties, E228 effectively prolongs the freshness and shelf life of food products, preventing spoilage and color changes.
This substance is a potassium salt of sulfuric acid, characterized by a strong preservative effect. It is particularly popular in wine processing, fruit juices and dried fruit production, where it prevents fermentation and oxidation processes.
Properties of potassium bisulfite
E228 exhibits strong antibacterial and antioxidant properties, so it effectively protects food from the harmful effects of microorganisms and the oxidation process. This is particularly important in preserving the color and aroma of food products, which is crucial to maintaining their quality and appeal to the consumer.
Uses of potassium bisulfite
It is mainly used as a preservative in the wine industry, where it prevents fermentation and oxidation of wine. In addition, it is often used in the production of juices, dried fruits, and in some meat and vegetable products to preserve their freshness and color.
Where to buy potassium bisulfite?
E228 is available at specialty stores selling raw materials for the food industry, as well as some online food chemicals stores. It is usually sold as a powder or solution, making it easy to dispense and use in the production process.
Potassium hydrosulfite and its functions in food
As a preservative, E228 plays a key role in ensuring food safety and quality. By inhibiting the growth of microorganisms and preventing oxidation, potassium hydrosulfite effectively extends the shelf life of food products while maintaining their natural organoleptic properties. It is therefore an indispensable ingredient in the food industry, especially where long shelf life and consistent product quality are important.
