Appearance

White to slightly yellowish fine crystalline powder

Function

Potassium metabisulfite is a common wine or must additive, in which it forms sulfur dioxide gas (SO2). This both prevents most wild microorganisms from growing, and it acts as a potent antioxidant, protecting both the color and delicate flavors of wine. Potassium metabisulfite is sometimes used in the brewing industry to inhibit the growth of wild yeasts, bacteria, and fungi. It is also sometimes added to lemon juice as a preservative.

Synonyms

Potassium Pyrosulfite; Dikaliumdisulfit; Potassium Disulfite; Potassium Metabisulfite
