Product Description

Presenting Premium Economical Food Preservatives: Sodium Metabisulfite.

Sodium Metabisulfite Sodium Metabisulfite is an exquisite white or yellow crystalline powder or small crystal, boasting a strong, distinctive SO2 aroma. With a specific gravity of 1.4, it dissolves seamlessly in water, creating an acidic aqueous solution. On encountering a robust acid, it liberates SO2 and forms a corresponding salt. Be aware, exposure to air leads to oxidation, as its chemical structure is Na2S2O5, indicating limited storage longevity. At temperatures exceeding 150 degrees Celsius, it decomposes, releasing SO2.
