Sodium Metabisulfite is an inorganic chemical formula that’s also known as sodium pyrosulfite and sometimes referred to disodium or metabisulfite.  It’s created by evaporating sodium bisulfite and sulfur dioxide which leaves behind a white or yellow solid.  It is a then turned into a powder for use.  This has a wide variety of uses as a preservative, disinfectant, and antioxidant.  It’s known as E223, which is a food additive that preserves and adds antioxidants to food.  Home winemakers and homebrewers may use this when it comes to cleaning and sanitizing their equipment.  It can also be added to wine as a source of SO2, which is a bactericide and antioxidant.  It’s also used to clean desalination systems’ potable water reverse osmosis membranes.  It may also be used after drinking water has been treated by removing the chemical chloramine.  Photographers can also use this chemical.  It can also be used for bleaching coconut cream. It is used as reductant of the developing agent and protective agent for the fixative in photographic industry.
