Potassium Metabisulfite

Also known as Potassium Pyrosulfate, Potassium Metabisulfite is a white crystalline powder with a pungent sulfur odor.  The main uses are as a common wine or must additive, in which it forms sulfur dioxide gas (SO₂).  This prevents most wild microorganisms from growing and acts as a potent antioxidant, protecting both the color and delicate flavors of wine.  The brewing industry uses Potassium Matabisulfite to inhibit growth of wild bacteria and fungi.  This is called 'stabilizing'.   It is also used to neutralize chloramine that has been added to tap water at the sources as a disinfectant.  The food industry uses Potassium Metabisulfite as a preservative when added to lemon juice.

Packaging: 1 kg & 25 kg bag
