Sodium Metabisulphite, or SMBS, is a multipurpose inorganic substance that finds use in many different industries. Its chemical formula is sodium metabisulphite (Na₂S₂O₅). Food processing, water treatment, medicines, textiles, and more all depend on sodium meta bi sulfite because of its strong antioxidant and preservative qualities.

Sodium Meta Bi Sulphite’s primary uses, chemical characteristics, and leading industrial applications are examined in this article, along with the reasons SNDB is one of India’s top exporters of high-purity SMBS.

What is Sodium Meta Bi Sulphite?

A white, crystalline powder, sodium meta bi sulphite has a strong, sulfur-like smell. The key ingredient in its antibacterial and antioxidant properties, sulfur dioxide (SO₂), escapes as it breaks down in acidic conditions and is very soluble in water.

Chemical Formula: Na₂S₂O₅

Molecular Weight: 190.10 g/mol

Appearance: White or off-white crystalline powder

Purity: Available in industrial, technical, and food grades (up to 97% purity)

Key Properties of Sodium Meta Bi Sulphite

• Excellent preservative and antioxidant
• Powerful reducing agent
• Sulfur dioxide (SO₂) release upon decomposition
• Good solubility in water
• Effective microbial inhibitor

Top Industrial Applications of Sodium Meta Bi Sulphite

1. Food Industry

• Serves as a color stabilizer and preservative in processed vegetables, juices, and dried fruits.
• For bleaching starch and coconut cream.
• Stops food packaging from oxidizing and spoiling.

2. Water Treatment

• Utilized to dechlorinate water in industrial and municipal wastewater.
• Before returning water to the environment, it neutralizes any remaining chlorine.

3. Textile & Leather Industry

• Serves as a bleaching agent during the dyeing and processing of textiles.
