Sodium Metabisulfite (CAS 7681-57-4) is a chemical compound that is widely used in various industries due to its high-quality nutritional and functional properties. It is particularly known for its strong reducing capabilities and is commonly used as a preservative, antioxidant, and bleaching agent in food products.
In the food industry, sodium metabisulfite serves multiple purposes:
It is also used in winemaking to prevent oxidation and microbial growth, and in the processing of fruits and vegetables to maintain their freshness and color. In baking, it can act as a dough conditioner, improving the texture and extendibility of the dough.
However, it's important to note that the use of sodium metabisulfite in food is regulated because it can cause allergic reactions in some individuals, especially asthmatics. It is not permitted in certain countries for use in meat products due to potential adverse health effects.
In addition to its applications in food, sodium metabisulfite is used in water treatment to remove chlorine and as a reducing agent in the mining industry, particularly in copper and gold flotation processes. It is also used in cosmetics for its skin-friendly properties and in the paper industry for bleaching.
