Product Description

Experience the Excellence of Premium Economical Food Preservatives: Sodium Metabisulfite

Sodium Metabisulfite: Unparalleled Quality for Reliable Food Preservation Our Sodium Metabisulfite is a high-purity, white or yellow crystalline powder or small crystal known for its strong SO2 aroma. With a specific gravity of 1.4, this versatile compound is highly soluble in water, forming a mildly acidic solution. On exposure to strong acids, it liberates SO2, creating salts, and upon air exposure, it oxidizes quickly. Its chemical composition is Na2S2O5, necessitating prompt usage as the product is sensitive to long-term storage. Beyond 150°C, SO2 decomposes, evidencing its reactive nature.
