Elevate your culinary creations with our Premium Economical Food Preservatives, featuring Sodium Metabisulfite. This essential ingredient ensures the freshness and longevity of your products.
Discover the powerful preservation capabilities of Sodium Metabisulfite, a trusted ingredient in the industry. Sodium metabisulfite is a versatile white or yellow crystalline powder, or small crystals, exuding a potent SO2 aroma. With a specific gravity of 1.4, it dissolves easily in water, turning the solution acidic. Upon exposure to strong acids, it liberates SO2, transforming into its corresponding salt. Left in the open air, it naturally oxidizes. Its chemical formula is Na2S2O5, reflecting its inherent instability for prolonged storage. At elevated temperatures above 150 degrees Celsius, it decomposes, releasing SO2.
