Product Name: Food Grade Sodium Metabisulfite/sodium pyrosulfite SO2 65%
Application: Used as a food preservative. It is a slight hazy
solution free from inappropriate impurities. These sulphites are
available in white and faint cream crystalline free flowing powder
and are widely used in photographic chemical and preservative
chemical.Used in medicine when producing chloroform,solasulfone and
methnylal;used as coagulant in rubber industry; used as dechlorided
agent or assistants in printing and dyeing industry; used to
improve leather properties in leather industry; used as developing
agent in photosensitivity industry; used when producing hydroxyl
geranial, hydrochloric hydroxylamine in chemical industry; used as
bleaching agent, antiseptics, antioxidant, ect.in food industry.
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.
molecular formula: Na2S2O5
Appearance: white crystal powder
|Heavy metal(Pb mg/kg)||≤5.0||<5||qualified|
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
