What it is

Sodium metabisulfite is a white or slightly colored crystalline powder. It is a salt of sulfurous acid, commonly produced by reacting sulfur dioxide with a solution of sodium carbonate or sodium hydroxide. It is often used as a preservative and antioxidant in various food products.

Why it's used

Sodium metabisulfite is added to foods to prevent spoilage by inhibiting the growth of bacteria and molds. It also acts as an antioxidant, preventing browning and preserving the color and flavor of foods. It is frequently found in dried fruits, processed potatoes, wine, and baked goods.

Health notes

In the United States, 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. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sodium metabisulfite and established an acceptable daily intake. EFSA has also evaluated its safety.

Allergen info

Not a major allergen. However, individuals with sulfite sensitivity may experience reactions.
