Sodium Metabisulfite is one of sodium salts, it is a kind of inorganic compound, also called Sodium Pyrosulfite or spelled as Sodium Metabisulphite. The product is white or slightly yellow crystalline powder, with a gentle or heavy smell of SO2. Sodium metabisulfite plays important roles in modern industries as a preservative, bleaching agent, leavening agent, antioxidant, color fixative, mold inhibitor, coagulant, dechlorinate agent, cotton fabric cooking agent, reductant, mineral processing agent, concrete water reducing agent, etc.. The product can also be used for the production of sodium hydrosulfite, chloroform, phenylpropylsulfone, benzaldehyde, sulfamethazine, metamizole, caprolactam, and etc..
As the leading Sodium Metabisulfite China manufacturer,Qingdao Tianya Chemical Co., Ltd produces high quality Sodium Metabisulfite products with wide applications.
Application of Sodium Metabisulfite Food Grade:
Sodium Metabisulfite food grade is mainly applied to food industry, feed industry, cosmetics and skin care products, also use for water treatment and other fine chemicals field.
Sodium Metabisulfite food grade is used in food industry as preservative, bleaching, leavening agent, antioxidant, and color protector.
Antiseptic agent: Sodium Metabisulfite can be used for fruit juice, preserves, and canned food, can extend its shelf life and effectively sterilize it.
Bleaching agent: Sodium Metabisulfite can be used for flour in the production of pastries and other foods for bleaching.
Leavening agent: Sodium Metabisulfite can make the structure of bread and biscuits become loose, and the taste becomes relatively crispy.
Antioxidant preservatives: Sodium Metabisulfite has good antioxidant and preservation effects on seafood, fruits, and vegetables, etc.
Protector: in the processing and preservation of light colored vegetables, such as mushrooms, lotus roots, water chestnuts, bamboo shoots, yams, etc. sodium metabisulfite food grade solution can be used as color protection.
preservative and antiseptic: Sodium Metabisulfite can be used in feed field as feed additive.
Reductant: Sodium Metabisulfite can be used in water treatment as a reductant. For example, in electroplating wastewater treatment, in the treatment of wastewater containing hexavalent chromium, Sodium Metabisulfite can be added first. After a full reduction reaction, polyaluminum chloride or polymeric ferric sulfate flocculant can be added after alkali adjustment, and finally sodium sulfide can be added to remove the heavy metals that have not been settled.
Anti oil oxidants and preservatives: Sodium Metabisulfite can be used in cosmetics and skincare products to prevent and delay product deterioration caused by oxidation reactions.
