Introducing our Premium Economical Food Preservatives: Sodium Metabisulfite!
Sodium Metabisulfite: Your Trusted Food Preservative Sodium Metabisulfite is a versatile compound appearing as a white or yellow crystalline powder or small crystals, characterized by a potent SO2 scent. It boasts a specific gravity of 1.4 and dissolves effortlessly in water, creating an acidic solution. Upon contact with strong acids, it releases SO2 to form corresponding salts. Exposure to air leads to oxidation, and due to its chemical nature (Na2S2O5), it is not suitable for prolonged storage. At temperatures exceeding 150°C, it decomposes, releasing SO2.
