Sodium Metabisulphite is an inorganic compound containing soda, sulfur and oxygen. Easily soluble in water, leaving the familiar sulfur smell (rotten egg).

  1. Sodium metabisulphite in food:

Sodium metabisulphite is commonly used as a preservative for dried foods such as potato chips, raisins, and apples, as well as fruit concentrate juices. As a food product, the safe daily intake of sodium metabisulphite has been determined to be around 0.7 grams per kilogram of body weight. However, people with sulphite allergy - often manifested by rashes, hives, and wheezing - may try to avoid this preservative altogether.

  1. Sodium metabisulphite as a cleaning agent:

Sodium metabisulphite is also present in wines and beers as it is used both as a sterilizer and an antioxidant in the beer brewing or wine fermentation process. If you or someone you know says they are allergic to red wine, it's probably because of the presence of sodium metabisulphite.

  • Also used in the process of water purification, cleaning of water pipes and reverse osmosis membranes in desalination plants as it has an antibacterial effect.
  1. Sodium metabisulphite in other applications:

The acidic and preservative properties of sodium metabisulfite also make it an effective replacement for sodium bisulphite, a chemical used in traditional darkroom photography. In addition, sodium metabisulphite is used as a bleaching agent in the production of pulp and textiles, and also as a reducing agent in pharmaceuticals. It is also a well-known preservative in cosmetics.

  • Also used in landscape gardening as a tree stump remover as it breaks down lignins - chemicals in plant cell walls - in the stumps, making it easier to remove.
