Product Overview

• Sodium Bisulfite, chemically Sodium Hydrogen Sulfite, is an inorganic reducing agent and preservative compound widely used across water treatment, food processing, and chemical manufacturing industries. It appears as a white to pale yellow crystalline powder or granular solid with a characteristic sulfurous odor, and is highly soluble in water, forming a mildly acidic solution. Procorbay International supplies industrial-grade and food-grade Sodium Bisulfite serving as a dechlorination agent in water treatment, an antioxidant/preservative in food processing, and a reducing agent across various chemical manufacturing applications.
• Sodium Bisulfite is manufactured through the reaction of sulfur dioxide gas with sodium carbonate or sodium hydroxide solution under controlled conditions, followed by crystallization and drying to achieve the required purity grade. Procorbay sources Sodium Bisulfite from established sulfur chemical manufacturers with consistent quality control over purity, sulfur dioxide content, and heavy metal specifications across both industrial-grade and food-grade material.
• Industrially, Sodium Bisulfite serves a critical dechlorination function in water and wastewater treatment, neutralizing residual chlorine before discharge or further processing, and functions as an oxygen scavenger in boiler water treatment to prevent corrosion. In food processing, it serves as an antioxidant and preservative, preventing enzymatic and non-enzymatic browning in processed fruits, vegetables, and wine production (as a sulfiting agent), subject to food-grade purity and regulatory compliance. It also functions as a reducing agent in textile bleaching and dyeing processes, in photographic processing chemistry, and as a raw material in the synthesis of various sulfonate and sulfite-derivative specialty chemicals.
• Given its broad cross-industry relevance spanning water treatment, food processing, and textile chemistry, Procorbay maintains consistent, multi-grade Sodium Bisulfite supply to serve buyers across these applications.
