What it is
Sulfur dioxide (SO2) 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. In food, it's typically used in the form of sulfites, which are salts of sulfurous acid.
Why it's used
Sulfur dioxide and sulfites act as preservatives by preventing the growth of bacteria, yeast, and mold. They also function as antioxidants, protecting foods from browning and spoilage. They are commonly found in dried fruits, wines, and processed meats.
Health notes
Sulfur dioxide and sulfites are generally recognized as safe (GRAS) by the FDA when used as preservatives. However, some individuals, particularly those with asthma, may experience sensitivity reactions. The FDA requires sulfites to be declared on food labels if they are present at levels of 10 parts per million or more. JECFA and EFSA have evaluated sulfites and established acceptable daily intake levels.
Allergen info
Sulfur dioxide and sulfites are not derived from any of the 9 FDA major allergens. They do not contain gluten.
