What is sulfur dioxide in food?

Sulfur dioxide is a commonly used food preservative and antioxidant. It is added to foods such as dried fruits, wine, and fruit juices to prevent bacteria growth and preserve freshness.

Sulfur dioxide works by inhibiting the growth of molds and bacteria, which helps prevent spoilage and prolongs the shelf life of the food. It also helps maintain the color and flavor of foods, particularly dried fruits and vegetables.

However, some individuals may be sensitive or allergic to sulfur dioxide, experiencing symptoms such as asthma, respiratory issues, and skin irritation. Therefore, it is important for food manufacturers to label products containing sulfur dioxide to alert consumers with sensitivities.

Overall, sulfur dioxide is generally recognized as safe by the FDA when used in accordance with regulations and in appropriate amounts. It is an effective and widely used food preservative that helps maintain the quality and safety of various food products.
