What it is
Sulfur dioxide is a chemical compound that occurs naturally in small amounts in some foods and beverages. It is produced industrially by burning sulfur. In food processing, it is often used in its salt forms, such as sodium sulfite or potassium bisulfite.
Why it's used
Sulfur dioxide and its related compounds are used as preservatives in dried fruits, wines, and some processed foods. They prevent spoilage by inhibiting the growth of bacteria, yeasts, and molds, and also act as antioxidants to prevent browning.
Health notes
Sulfur dioxide is generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. Some individuals, particularly those with asthma, may be sensitive to sulfites and experience reactions. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sulfites and established acceptable daily intakes.
Allergen info
Sulfites are not one of the 9 FDA major allergens. They do not contain gluten.
