With Sulfites

Sulfites are compounds that contain sulfur and oxygen. They occur naturally in small amounts in some foods and are also produced by the body. For food use, sulfites are typically manufactured.

Sulfites are used as a preservative to prevent spoilage and maintain the color and flavor of foods. They act as antioxidants and antimicrobials. They are commonly found in dried fruits, wine, pickles, olives, and some baked goods.

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, such as hives or breathing difficulties. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sulfites and established acceptable daily intake levels. Evidence regarding sulfite sensitivity is mixed, with some studies suggesting a higher prevalence in asthmatics than in the general population.
