What is SODIUMMETABISUFITE?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is E223 which has developed particularly rapidly in recent years. Do you know about E223?
- The official answer: Sodium metabisulfite (Na2S2O5), an inorganic compound, is white or yellow crystals, with a strong irritating odour, soluble in water, the aqueous solution is acidic, and contact with strong acids will release sulfur dioxide and generate the corresponding salts. If it is left in the air for a long time, it will be oxidized into sodium sulfate, so sodium metabisulfite cannot be stored for a long time.
What’s the application of SODIUMMETABISUFITE?
In food processing as a preservative, bleaching agent, loosening agent. In industry, sodium metabisulfite is used in printing and dyeing, organic synthesis, printing, tanning, pharmaceuticals and other sectors; sodium metabisulfite is used in chemical and pharmaceutical industries for the production of insurance powder, sulfa-dimethyl pyrimethamine, caprolactam and the purification of chloroform, phenyl propyl sulfone and benzaldehyde.
