Shandong Jinyang industry Co.,Limited was founded in 2009, As a specialized supplier of sodium metabisulfite, we enjoy 50% stock at a local factory. The factory annually produces 800,000 tons of sodium metabisulfite. There are two kinds of specifications, including Food Grade, Industrial grade, thus our products can meet the demands of customers in the fields of food,chemical industry, mining and water treatment. in addition,our sister company Henglink International Limited as a specialized supplier of various chemicals and solutions to customers home and abroad .
Sodium metabisulfite is a white or yellow crystalline powder or small crystal with a strong SO2 odor, a specific gravity of 1.4, soluble in water, and the aqueous solution is acidic. When it is in contact with a strong acid, it releases SO2 to form a corresponding salt. When it is left in the air, it oxidizes. It is Na2S2O6, so the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.

Magnesium sulfate is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is
strongly hygroscopic and often encountered as the heptahydrate sulfate mineral epsomite (MgSO4â?¢7H2O), commonly called Epsom
salt.And the monohydrate, MgSO4â?¢H2O, is found as the mineral kieserite.In food preparation, magnesium sulfate is used as a brewing
salt in beer production or used as a coagulant for making tofu.
