What it is

Sodium bisulfite is a chemical compound made from sulfur dioxide. It is often used as a preservative in foods to prevent spoilage from bacteria and fungi. It is also used to prevent browning in fruits and vegetables.

Why it's used

Sodium bisulfite is added to foods to preserve them and maintain their color and freshness. It is commonly found in dried fruits, processed potatoes, and some wines and juices. It acts as an antioxidant and antimicrobial agent.

Health notes

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 FDA major allergens. It does not contain gluten.
