Descripción del Producto
Sodium Metabisulfite Powder - Food Preservative E223, Water Dechlorinator, Antioxidant Agent
Sodium metabisulfite (chemical formula Na₂S₂O₅) is a white or slightly yellowish crystalline powder with a characteristic sulfur dioxide odor. This versatile product serves as a crucial multi-functional reducing agent, preservative, and antioxidant with essential applications across multiple industries.
Core Applications & Industry Uses
Food Industry Applications
As an internationally recognized food additive (INS 223, E223), sodium metabisulfite is widely used as a preservative, bleaching agent, and antioxidant. It effectively inhibits microbial growth including molds, yeasts, and bacteria to prevent food spoilage. As an antioxidant, it prevents enzymatic and non-enzymatic browning in various food products.
- Preserves color, flavor, and nutritional value in dried fruits and vegetables
- Used in dehydrated potatoes, mushrooms, nuts, and wine production
- Serves as bleaching and decolorizing agent in starch and sugar refining
Water Treatment Solutions
In aquaculture, potable water treatment, and industrial water systems, sodium metabisulfite functions as an efficient and economical dechlorinator and deoxidizer. It rapidly reacts with residual disinfectants and dissolved oxygen to eliminate toxicity and protect sensitive equipment.
- Neutralizes chlorine toxicity for fish and microorganisms
- Protects reverse osmosis (RO) membranes from oxidative damage
- Essential for RO system pretreatment and maintenance
Chemical & Pharmaceutical Applications
Sodium metabisulfite serves as an important reducing and sulfonating agent with diverse industrial applications:
- Textile Industry: Dechlorinating agent after fabric bleaching and reducing agent for vat dyes
- Leather Tanning: Used in depilation and post-tanning processes
- Mineral Processing: Acts as depressant or activator for metal ore flotation
- Pharmaceuticals: Reducing agent in drug synthesis and container sterilization
Environmental Protection
In wastewater treatment applications, sodium metabisulfite effectively treats wastewater containing heavy metals like chromium (VI), reducing it to less toxic trivalent chromium for precipitation and removal. It also removes residual chlorine to meet stringent discharge standards.
