Application of Sodium Metabisulphite:
Sodium Meta Bi Sulphite is one of a group of preservatives known as bisulphite. It is a food preservative, cosmetic and industrial bleaching agent, and an ingredient in the developing solution for film and photography. Evidence exists that it is also an immune-system toxin. As part of the group of sulfites, sodium metabisulphite can provoke reactions in people, particularly asthmatics, ranging from gastrointestinal discomfort and hives to asthma attacks.

Sodium Metabisulfite is a white to slightly yellowish crystalline powder with sulfur dioxide odor; readily soluble in water. Sodium metabisulfite containing more than 65.0% SO2 w/w releases sulfur dioxide gas when mixed with water. It forms a bisulfite adduct with aldehyde and with ketones to a sulfonic acid. It is used to purify or isolate aldehydes and ketones.

Sodium metabisulfite's reductive and sulfonating properties provide versatile applications.

It is used as an oxygen scavenger to eliminate the dissolved oxygen in waste water and in pipes.

Bisulfite is a reductive bleaching agent. It reduces carbonyl and alcohol groups, which function as colorants of the substances.

It is used in bleaching mechanical paper pulp, cotton, wool and kaolin clay. Additional applications include as a preservative (antioxidant), a hair waving agent, and Ensiling agent.

Bisulfites are used in industries concerned with leather processing, food and beverage processing, gas purification, water treatment to remove excess chlorine, textiles and pulp processing, and many others.

It is used as a reducing agent in chemical manufacturing.

It is an alternative to sulfur dioxide which is used in sterilization of equipments.

Food Uses
Sodium Meta Bi Sulphite is used as a preservative in foods such as baked goods, jams, wines, dried fruit and many sauces. Sulphite can be added before or after cooking. Fruits and raw vegetables used to be sprayed with sulphite, but this practice was banned by the U.S. Food and Drug Administration in 1986. Sodium metabisulphite is also used as an antibacterial agent in wine, although some manufacturers have begun using potassium metabisulphite instead. Some winemakers have claimed that sodium metabisulphite increases the sodium content of wine.

Industrial Uses
Sodium Meta Bi Sulphite exists in both food-grade and non-food-grade forms. The non-food-grade form is an industrial bleaching and reducing agent; it is also used to remove excess chlorine from drinking water and as a photographic developing and fixing bath agent.

Medicinal Use:
Sodium Meta Bi Sulphite is an antioxidant additive in injectable medicines and is also used as a reducing agent in pharmaceuticals. Some medical lotions may contain sodium metabisulphite; even in topical preparations, however, sodium metabisulphite may induce allergic or sensitive reactions.
