Antioxidant in Food Industry: It is widely used in the food industry as a potent antioxidant. For instance, in the processing of fruits and vegetables, it inhibits enzymatic browning by preventing the oxidation of phenolic compounds, thus maintaining the natural color and nutritional value of the products. In winemaking, it plays a crucial role in preventing the oxidation of wine, which helps to preserve its flavor, aroma, and overall quality, and also extends its shelf life.

Bleaching Agent in Textile and Paper Industries: In the textile industry, it is employed as a bleaching agent to remove natural pigments and impurities from fabrics, resulting in a whiter and brighter appearance. Similarly, in the paper-making industry, it helps to improve the whiteness of paper by bleaching the pulp, which enhances the visual quality of the paper products.

Disinfectant and Preservative: Sodium metabisulfite possesses antimicrobial properties, making it useful as a disinfectant and preservative. In water treatment, it can kill bacteria and algae, thereby improving water quality. It is also used in the preservation of certain medical supplies and cosmetics to inhibit the growth of microorganisms, ensuring the safety and efficacy of these products over time.

Reducing Agent in Chemical Reactions: In various chemical processes, it functions as a reducing agent. For example, in the pharmaceutical industry, it is involved in the synthesis of certain drugs, where it participates in reduction reactions to modify the chemical structure of compounds. In the metal-plating industry, it helps to reduce metal ions, facilitating the formation of a uniform and adherent metal coating on the substrate.
