Introducing our Premium Economical Food Preservative: Sodium Metabisulfite, expertly crafted to enhance the longevity and freshness of your food products. A top-tier choice for quality preservation!
Sodium Metabisulfite Sodium Metabisulfite is a versatile, white or yellow crystalline powder or small crystal, characterized by its distinct SO2 odor. With a specific gravity of 1.4, it is highly soluble in water, producing an acidic solution. Upon interaction with strong acids, it releases SO2, forming corresponding salts. Note: exposure to air causes oxidation, affecting its stability. As Na2S2O5, it is vital to store the product carefully, avoiding prolonged exposure. At temperatures exceeding 150 degrees Celsius, it decomposes, releasing SO2.
