The white, crystalline powder sodium metabisulfite, or sodium metabisulfite (Na₂S₂O₅), has a strong sulfurous smell. Its powerful reducing properties make it a common bleaching, preservative, and disinfectant. Sodium hydroxide or carbonate and sulfur dioxide react to form sodium metabisulfite. Its potent antibacterial and antioxidant qualities have led to its extensive use across numerous sectors.
Applications of Sodium Meta Bisulfite
- Food and Beverage Industry: In the food and beverage industry, sodium metabisulfite serves mainly as an antioxidant and preservative. It aids in keeping fruits, vegetables, and drinks like wine and fruit juices from browning and maintaining their color. Additionally, it helps to prolong the shelf life of a variety of processed foods.
- Water Treatment: By neutralizing chlorine and chloramine, Na₂S₂O₅ is used in water treatment to dechlorinate water. As a result, it is crucial to the treatment of industrial effluent and the purification of drinking water.
- Pharmaceutical Industry: The pharmaceutical sector uses sodium metabisulfite because of its antioxidant qualities. In the formulation of certain medications and injections, it helps to stabilize active pharmaceutical ingredients (APIs) that could otherwise degrade due to oxidation.
