Prepared With Sulfites Retention

Sulfites are compounds containing sulfur and oxygen. They occur naturally in some foods and are also added to foods. In food processing, sulfites are used to prevent spoilage and maintain color.

Sulfites act as a preservative by inhibiting the growth of bacteria, yeasts, and molds. They also prevent oxidation, which can cause browning and loss of flavor in foods. They are commonly found in dried fruits, pickles, olives, and processed potatoes.

In the US, sulfites are regulated by the FDA as a food additive. Some individuals, particularly those with asthma, may be sensitive to sulfites and experience allergic-type reactions. The FDA requires foods containing more than 10 parts per million of sulfites to declare their presence on the label. JECFA and EFSA have evaluated sulfites and established acceptable daily intakes.
