Product Introduction
Description
- Sodium metabisulfite (Na₂S₂O₅) is an inorganic substance. It appears as white or yellow crystals and has a powerful, pungent odor. This compound is soluble in water, and its aqueous solution exhibits acidity. When it reacts with strong acids, sulfur dioxide is released, and corresponding salts are formed. The primary role of sodium metabisulfite is that of an oxidizing agent. In food processing, it is predominantly utilized as a preservative, bleaching agent, and loosening agent. Specifically, in the brewing industry, sodium metabisulfite is frequently employed as a preservative.
