Sulfites Added

Sulfites are a group of chemical compounds containing 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 synthetically.

Sulfites are added to foods as preservatives to prevent spoilage and maintain color. They act as antioxidants, inhibiting browning in fruits and vegetables and preventing the oxidation of wine and dried fruits. They are commonly found in dried fruits, wine, processed potatoes, and some baked goods.

In the US, sulfites are regulated by the FDA. Foods containing added sulfites at levels of 10 parts per million or more must declare them on the label. Some individuals, particularly those with asthma, may experience sensitivity reactions to sulfites. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sulfites and established acceptable daily intakes. The European Food Safety Authority (EFSA) has also assessed sulfites.
