- Industrial Uses
The many chemical properties of Sodium metabisulphitemake it a versatile compound useful in many applications. Sodium metabisulphite can eliminate dissolved oxygen in waste water and in pipes. Sodium metabisulphite functions as a bleaching agent, which is useful in making paper pulp, cotton and wool. Sodium metabisulphite is used in water treatment plants to remove excess chlorine. In beer and wine manufacturing, Sodium metabisulphite is often used to sterilize the equipment.
- Food Preservative
Sodium metabisulfite is used as a food preservative. Sodium metabisulphite is commonly used as a food preservative for dried foods, like potato chips, raisins and apples, as well as fruit concentrate juices. Sodium metabisulphite acts as an antimicrobial, inhibiting the growth of fungi and bacteria, thereby keeping food fresh and safe.
- Medicinal Use
Sodium metabisulphite is an antioxidant additive in injectable medicines and is also used as a reducing agent in pharmaceuticals.
- Sodium Metabisulfite as a Cleaner
Sodium metabisulphite is also present in wines and beers, as it is used as both a sterilizer and an antioxidant in the process of brewing beer or fermenting wine. Sodium metabisulphite is also used in the process of purifying water, cleaning water pipes and reverse osmosis membranes in desalinization equipment as it is an antibacterial.
- Sodium Metabisulfite in Other Uses
Sodium metabisulphite acidic and preservative properties also make it an effective substitute for sodium bisulfite, a chemical which is used in traditional darkroom photography.
Also, Sodium metabisulphite is used as a bleaching agent in pulp and textile manufacture, as well as a reducing agent in pharmaceuticals.Sodium metabisulphite is also a known preservative in cosmetics.
The chemical, in concentrated form, has also been used in landscape gardening as a tree stump remover, as it disintegrates the lignin -- chemicals in plant cell walls -- in the tree stumps, making them easier to remove.
