Including Sulfites

Sulfites are a group of preservatives that occur naturally in some foods and are also added to others. They are chemical compounds containing sulfur and oxygen. In food, they are used to prevent spoilage and maintain color.

Sulfites act as antioxidants and antimicrobial agents, helping to preserve food quality and extend shelf life. They are commonly found in dried fruits, processed meats, baked goods, and some beverages like wine and beer to prevent browning and spoilage.

Sulfites are generally recognized as safe (GRAS) by the FDA for use in food, though they must be declared on labels if present above 10 parts per million. Some individuals, particularly those with asthma, may experience sensitivity reactions to sulfites, ranging from mild to severe. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated sulfites, and regulatory bodies continue to monitor their use and safety.
