Food grade sodium metabisulfite / bleach / Preservatives

Commonly known as: heavy thioredoxin formula: Na2S2O5 Molecular Weight: 190.10 Properties: Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong SO2 smell, specific gravity 1.4, soluble in water, acidic aqueous solution, with a strong acid in contact with the release of SO2 and generate the corresponding salts, long home air, the oxidation of Na2S2O4, so the product can not go far. Higher than 1500C, decomposition of the SO2. Quality Standard: Food additives according to GB 1893-86 sodium metabisulfite purposes: for dyeing, organic synthesis, printing, leather, pharmaceutical and other sectors in the industry; as anti-FU agents, bleaching agents, leavening agent in food processing.
