Discover the Ultimate Solution in Food Preservation with our Premium and Economical Sodium Metabisulfite! Designed to protect your culinary creations, this food preservative ensures long-lasting freshness.
Sodium Metabisulfite: Your Trusted Partner in Food Preservation. This remarkable compound presents itself as a white or yellow crystalline powder or small crystal, characterized by its distinct SO2 aroma. With a specific gravity of 1.4, it readily dissolves in water, forming an acidic aqueous solution. Upon contact with strong acids, it liberates SO2 to create its respective salt. Exposure to air results in oxidation, so it's best to utilize it promptly. Its chemical composition, Na2S2O5, is sensitive to prolonged storage. Above 150 degrees Celsius, it decomposes, releasing SO2.
