In baking, sodium metabisulfite is used in crackers to develop a soft and extensible dough and improve machinability during sheeting and rolling. It is also used for reducing mixing time requirements of flours. Sodium metabisulfite is used to reduce discoloration in fruits and to preserve wine and pharmaceutical preparations. In industrial water treatment, sodium metabisulfite is added to water to reduce oxygen and chlorine to help control the corrosion. In wastewater treatment, sodium metabisulfite is used to remove residual free and combined chlorine to protect aquatic life from toxic effects of residual chlorine. Additionally, formation of harmful chlorinated compounds in drinking water through reaction of residual chlorine with water-born organic materials can be reduced. Sodium metabisulfite can be easier to use than sulfur dioxide gas for chlorine control. Sodium Metabisulfite is available in 25 kg LDPE bags.
