Sodium Metabisulfite (Na₂S₂O₅) is a white crystalline powder that has a strong smell of sulfur, and is characteristically used as a preservative, disinfectant, and an antioxidant. It is imperative to public health and safety in industrial applications such as food processing, water treatment, medicine, and even in mining. These characteristics of sodium metabisulfite make it one of the most common food preservatives in preventing oxidation and rancidity of food and drink products. Chlorine removal as well as heavy metal removal are some of the functions of sodium metabisulfite in water treatment processes; and it is used in these functional capacities extensively.
The diversification of applications for sodium metabisulfite has proven to increase its market output potential, presenting vast opportunities in manufacturing.
What is Sodium Metabisulfite?
Sodium Metabisulfite is a non-organic compound with Sodium, Sulfur, and Oxygen within its structure. This compound goes into an aqueous solution and gives off Sulfur Dioxide (SO₂) gas, which is famous for its fungicidal and antioxidative properties.
This substance usually comes in packed granules; when water subjects it, it dissociates into bisulfite ions and sulfurous acid, which act as a reducing and bleaching agent. Its physical and chemical characteristics enable its use in diverse sectors from food storage to effluent management, as well as, involved in paper and clothing manufacturing.
Applications of Sodium Metabisulfite
- Food and Beverage Industry: Sodium metabisulfite is one of the most commonly used antioxidants in food and drink processing. It assists in preventing discoloration and primary deterioration of products such as fruit purees, vegetables, and juice. In viniculture and brewing, they use it to reduce the oxygen levels in the liquid and prevent oxygen from getting into the final product after filling it into bottles.
- Water Treatment: This compound is applied in the excess removal of chlorination process and any other metal pollutants in water before utilization for industrial and domestic activities. Industries use it in treatment plants to treat raw waste before allowing it to flow out.
- Pharmaceutical Industry: This reducing agent, sodium metabisulfite which is included in all formulations of sodium metabisulfite in the treatment of pharmaceutical drugs, is usually its reducing agent. It aids drugs in their therapeutic polysaccharide minimization development without your capsules undergoing evaporation or oxidation damage.
- Textile and Paper Industries: In paper and textile manufacture, sodium metabisulphite helps in bleaching of raw materials. It works in brightening up the substrates by making them free of color, hence enhancing their quality.
- Mining Industry: In mining, they use sodium metabisulfite to remove any dissolved heavy metals, preferably gold and other precious metals, that leach.
- Cosmetics Industry: In the cosmetic field, manufacturers use it as an antioxidant to prolong the shelf life of products like creams and lotions.

Production Method of Sodium Metabisulfite
On a high level, the production process of sodium metabisulphite has several phases:
Preparation of raw materials
Most existing raw materials for production of sodium metabisulfite are sodium carbon oxide(soda ash ) and sulfur dioxide SO2. SO2 may be produced by burning of sulfur and or may also be achieved as a waste from other industrial processes.
Reaction
In this process, we introduce sulfur dioxide gas into a solution of sodium carbonate. The sodium carbonate decomposes and forms sodium bisulfite. We carry this process on to a certain level of acidity, where the sodium bisulfite solution transforms into the sodium metabisulfite solution.
The chemical equation may be illustrated as below
SO2+Na2CO3→Na2S2O5+CO2SO_2 + Na_2CO_3 \right arrow Na_2S_2O_5 + CO_2SO2+Na2CO3→Na2S2O5+CO2
Crystallization
The aqueous solution undergoes concentration through evaporation. During this process, sodium metabisulfite is permitted to crystallize.
Filtration and Drying
The process filters the resulting crystals to eliminate any impurities. It then washes the crystals to enhance their purity. Finally, it evaporates any excess water from the purified crystals. This procedure yields sodium metabisulfite in solid form.
Packaging
Sodium metabisulfite is carefully collected and dried. It is then sealed in moisture-proof containers to ensure its protection. These containers help prevent dehydration during both transportation and storage.
