What is Potassium Metabisulphite?

Potassium Metabisulphite is a chemical compound commonly used as a preservative in the food and beverage industry. It is also known as potassium pyrosulfite and has the chemical formula K2S2O5. Potassium metabisulphite is an effective antimicrobial agent that inhibits the growth of bacteria, fungi, and yeast, thereby extending the shelf life of food products.

The manufacture of Potassium occurs by the reaction of sulphur dioxide with potassium hydroxide. This occurs via the below reaction:

2SO2 + 2KOH -> K2SO5 + H2O

Evaporating the solution leaves crystals of Potassium Metabisulphite for resale. The resulting compound is a white crystalline powder that is highly soluble in water. Further changes can occur if the heat reaches 190oC, decomposing Potassium Metabisulphite into Potassium Sulphite and Sulfur Dioxide.

Potassium metabisulphite is commonly used in the wine industry as a sterilizing and clarifying agent, as well as in the brewing industry to prevent the growth of bacteria and yeast.

In addition to the wine and brewing industries, potassium metabisulphite is used in a variety of other food products, such as dried fruits, fruit juices, and seafood. It is also used as a bleaching agent in the textile industry and as a reducing agent in the photographic industry. While generally considered safe, potassium metabisulphite can cause allergic reactions in some people and should be used in moderation.
