Uses

Food additive

It is used as a preservative and antioxidant in food and is also known as E223.[4]
It may cause allergic reactions in those who are sensitive to sulfites, including respiratory reactions in asthmatics, anaphylaxis and other allergic reactions in sensitive individuals.[5][6]
Sodium metabisulfite and potassium metabisulfite are the primary ingredients in Campden tablets, used for wine and beer making.[7]
The acceptable daily intake is up to 0.7 milligrams per kilogram of body weight.[8] Sodium metabisulfite oxidizes in the liver to sulfate which is excreted in the urine.[8]
Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na2S2O5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant and preservativeagent.

Sanitization and cleaning agent

It is commonly used in homebrewing and winemaking to sanitize equipment. It is used as a cleaning agent for potable water reverse osmosis membranes indesalination systems. It is also used to remove chloramine from drinking water after treatment.
