What it is
Sulfur dioxide is a gas that occurs naturally in small amounts but is often produced industrially. It is made by burning sulfur or by heating metal sulfides. It is commonly used in food as a preservative.
Why it's used
Sulfur dioxide is added to foods to prevent spoilage by inhibiting the growth of bacteria, yeasts, and molds. It also acts as an antioxidant, preventing browning in fruits and vegetables. It is often found in dried fruits, pickles, olives, and wine.
Health notes
Sulfur dioxide is generally recognized as safe (GRAS) by the FDA when used as a preservative. It can cause allergic-type reactions in some individuals, particularly those with asthma. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sulfur dioxide and established acceptable daily intake levels. Evidence regarding its effects at typical intake levels is generally considered mixed, with some studies suggesting potential benefits and others raising concerns.
Allergen info
Sulfur dioxide is not derived from any of the nine FDA major allergens. It does not contain gluten.
