Product Description

Industrial Grade 96% Crystalline or Powder Sodium Metabisulfite for Food Use

Product Information

Sodium metabisulfite (chemical formula: Na₂S₂O₅) is a high-efficiency inorganic chemical with strong reducing properties, widely used in food preservation, water treatment, textile printing, and pharmaceutical industries. It usually appears as white crystalline powder or small crystals, with a slight sulfur dioxide odor; it is easily soluble in water (aqueous solution is acidic) and soluble in glycerin, but insoluble in ethanol. It is sensitive to air and moisture—easy to absorb water and oxidize into sodium sulfate, so sealed storage is required.

• Reduction Potential: Sodium metabisulfite has strong reducing properties and can be oxidized to sodium sulfate (Na₂SO₄).

• Acidity: It exhibits weak acidity and can react with bases to form salts.

• Thermal Stability: Decomposes at temperatures above 150°C to release sulfur dioxide (SO₂).

Applications

1. Food Industry

• Preservative: Sodium metabisulfite is widely used as a preservative to inhibit the growth of yeast and bacteria, thereby extending the shelf life of food products.

• Antioxidant: It prevents oxidation and browning in foods such as wine, fruit juices, and dried fruits.

• Bleaching Agent: Used to bleach food products and maintain their color, particularly in the processing of dried fruits and candied fruits.

2. Water Treatment

• Chlorine Removal: Sodium metabisulfite is used to remove chlorine and chloramines from water, ensuring the safety and stability of water quality.

3. Pharmaceutical Industry

• Stabilizer and Antioxidant: Sodium metabisulfite is used as a stabilizer and antioxidant in pharmaceutical formulations to extend the shelf life of drugs and protect active ingredients.

4. Photography Industry

• Fixing Agent: In the photography industry, sodium metabisulfite is used in fixing baths to remove unexposed silver halides, ensuring the quality of photographic prints.

Packaging and Transportation

Packaging Options:

Standard: 25kg kraft paper bags with inner PE liners (moisture-proof, anti-oxidation, prevents SO₂ leakage).
Bulk: 1000kg jumbo bags (for industrial bulk orders, reducing transportation costs).
Custom: Branded packaging (printing your logo) and small-size packs (1kg-10kg) for retail or small-batch buyers
