Sodium Metabisulfite, with the chemical formula Na2S2O5 and CAS number 7681-57-4, is a versatile and widely used chemical compound in various industries. This compound is known for its strong reducing properties and excellent antioxidant capabilities, making it an essential ingredient in many industrial and food applications. Available in granularity of 80-100 mesh, Sodium Metabisulfite ensures optimal particle size for diverse processing requirements and efficient performance.
The product is offered in two primary grades: Food Grade and Industrial Grade. The Food Grade Sodium Metabisulfite meets stringent quality standards and purity requirements, making it safe and suitable for use as a preservative, antioxidant, and sterilizing agent in food processing. It is commonly used to prevent discoloration, spoilage, and oxidation in dried fruits, beverages, and other food products. The Industrial Grade, on the other hand, is designed for applications in industries such as water treatment, photography, textiles, and chemical manufacturing, where it serves as a bleaching agent, reducing agent, and oxygen scavenger.
With a molecular weight of 190.09, Sodium Metabisulfite is a white or yellowish crystalline powder that dissolves readily in water, releasing sulfur dioxide (SO2), which is primarily responsible for its preservative and antioxidant effects. This compound’s solubility and reactivity make it highly effective in controlling microbial growth and preventing oxidation in various environments. Its granular size of 80-100 mesh ensures consistent dispersion and ease of handling during industrial and food processing operations.
Classified as a non-hazardous chemical, Sodium Metabisulfite is generally safe to handle when used according to recommended guidelines. It does not pose significant risks under normal usage conditions, but appropriate safety measures should still be observed to avoid inhalation or direct contact, which can cause irritation. The non-hazardous classification enhances its appeal in applications requiring minimal regulatory restrictions and safe handling practices.
Sodium Metabisulfite’s applications extend beyond food preservation and industrial processing. It is used in photographic developing solutions to prevent oxidation of the developer, in leather manufacturing to remove excess chlorine, and in chemical synthesis as an intermediate reagent. Its versatility is supported by its controlled granularity of 80-100 mesh, ensuring that it can be used efficiently across these diverse sectors.

In the food industry, Sodium Metabisulfite is commonly used as a preservative and antioxidant to extend the shelf life of dried fruits, beverages, and processed foods. Its ability to inhibit microbial growth and prevent oxidation makes it an essential additive in food processing. Additionally, it is utilized in winemaking and brewing to control microbial activity and maintain product freshness.
The water treatment sector also benefits from Sodium Metabisulfite’s reducing properties. It is employed to remove excess chlorine and chloramine from water, making it safer for consumption and suitable for industrial use. This application is particularly important in municipal water treatment plants and aquaculture.
In the textile and paper industries, Sodium Metabisulfite serves as a bleaching agent and an anti-chlor agent. It helps in dechlorination processes and enhances the quality of finished products by preventing discoloration. Its role in photographic developing solutions further highlights its importance in various manufacturing processes.
