What it is
Sodium metabisulfite is a white or slightly yellowish crystalline powder. It is a salt of sulfurous acid, formed when sulfur dioxide dissolves in a solution of sodium carbonate or sodium hydroxide. It is used as a preservative and antioxidant.
Why it's used
Manufacturers add sodium metabisulfite to foods to prevent spoilage by inhibiting the growth of bacteria and fungi, and to prevent oxidation, which can cause browning and off-flavors. It is commonly found in dried fruits, wine, processed potatoes, and some baked goods.
Health notes
In the US, sodium metabisulfite is generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. It can cause allergic reactions in some individuals, particularly those with asthma, and may trigger symptoms like hives or breathing difficulties. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated sodium metabisulfite, establishing acceptable daily intake levels. Some people are sensitive to sulfites, which are released by sodium metabisulfite.
