Why it's used
Sulfur compounds are used in food for several purposes. For example, sulfites (a group of sulfur-based compounds) act as preservatives to prevent spoilage and maintain color in dried fruits, wines, and processed potatoes. Sulfur dioxide is also used as a bleaching agent for sugar and as an antimicrobial agent.
Health notes
Sulfites are generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. However, some individuals, particularly those with asthma, may experience sensitivity reactions to sulfites, such as hives, breathing difficulties, or stomach upset. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sulfites and established acceptable daily intakes. Evidence regarding sulfite sensitivity is well-documented, and foods containing sulfites above a certain level must be labeled.
Allergen info
Sulfur itself is not one of the nine major allergens. However, some sulfites are derived from ingredients that may be processed in facilities that also handle allergens, though sulfur compounds are not typically considered allergenic themselves.
