What it is

Sodium bisulfite is a chemical compound made from sulfur dioxide and sodium hydroxide. It is a white crystalline powder that dissolves in water. It is often used in food processing to prevent spoilage and maintain color.

Why it's used

Sodium bisulfite acts as a preservative by inhibiting the growth of bacteria and preventing oxidation, which can cause food to brown or spoil. It is commonly found in dried fruits, wine, and some processed foods like sauces and baked goods.

Health notes

In the U.S., sodium bisulfite 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 bisulfite and established an acceptable daily intake.

Allergen info

Sodium bisulfite is not derived from any of the nine major allergens. It does not contain gluten.
