Sulfites Sea Salt

Sulfites are compounds containing sulfur and oxygen. They occur naturally in some foods and are also produced by yeast during fermentation. In food production, sulfites are often added as preservatives.

Sulfites are used as preservatives 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, processed meats, and some baked goods.

Sulfites are generally recognized as safe (GRAS) by the FDA for use in food. However, some individuals, particularly those with asthma, may experience sensitivity reactions to sulfites, ranging from mild symptoms to severe allergic-type responses. JECFA and EFSA have evaluated sulfites and established acceptable daily intakes. The FDA requires sulfites to be declared on food labels when present at levels of 10 parts per million or more.
