Treated With Sulfur Dioxide And Sodium Sulfite

Sulfur dioxide (SO2) and sodium sulfite are chemical compounds used together. Sulfur dioxide is a gas, while sodium sulfite is a salt. They are often used in combination to prevent spoilage and maintain the appearance of foods.

These compounds act as preservatives and antioxidants. They help prevent browning in fruits and vegetables and inhibit the growth of bacteria and yeast. They are commonly found in dried fruits, wines, and some processed potato products.

Sulfur dioxide and sulfites are permitted food additives in the US and are generally recognized as safe (GRAS) by the FDA when used according to regulations. However, some individuals may be sensitive to sulfites, experiencing allergic-type reactions, particularly those with asthma. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated sulfites, and regulatory bodies have established guidelines for their use and labeling.
