sodium metabisulfite powder,
sodium meta bi sulphate
molecular formula: Na2S2O5
Appearance: white crystal powder
Sodium metabisulphite white or yellow crystalline powder or small crystallization, with strong smell, a proportion of SO2 1.4, soluble in water, become acidic aqueous solution, and acid contact is released SO2 generated corresponding salts, long for air, is oxidized to Na2S2O6, reason this product not far. Above 1500C, namely the SO2 decomposition.
Industrial used for printing and dyeing, organic synthesis, printing, the leather making, pharmaceutical and other department. In food processing of bleaching agent and antiseptic, osteoporosis agent.
Sodium Metabisulphite SM is used as a preservative in the starch and food industry to control melanosis (black spot) in shrimp; for fermentation in the wine industry; as an antichlor in the chemical industry and as a redox catalyst in the acrylic fibre industry.
The product is also used as a reducing agent in the purification of aldehydes and ketones; in the manufacture of sulphonated oil and resin; for detoxification of cyanide in gold ore processing plants and in the manufacture of photographic chemicals.
It is used as a preservative and antioxidant in food and is also known as E223.
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.
Sodium metabisulfite and potassium metabisulfite are the primary ingredients in Campden tablets, used for wine and beer making.
The acceptable daily intake is up to 0.7 milligrams per kilogram of body weight. Sodium metabisulfite oxidizes in the liver to sulfate which is excreted in the urine.
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.
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.
