Sulfite Treated To Retain Color

Sulfites are compounds containing sulfur and oxygen. They are naturally present in small amounts in some foods and are also produced by the body. For food use, they are often added to fruits and vegetables, like apples, to prevent browning and maintain their fresh appearance.

Sulfites are added to foods to preserve their color and prevent spoilage. They act as antioxidants, stopping fruits and vegetables from turning brown when exposed to air. They are commonly found in dried fruits, processed potatoes, and baked goods like cakes and pastries.

In the US, sulfites are approved food additives and are generally recognized as safe (GRAS) when used as intended. However, some people are sensitive to sulfites and may experience allergic-type reactions, particularly those with asthma. The FDA requires foods containing more than 10 parts per million of sulfites to declare them on the label. JECFA and EFSA have evaluated sulfites and established acceptable daily intakes.
