Sodium Bisulfite Added To Help Promote Color

Sodium bisulfite is a chemical compound made from sulfur dioxide and sodium hydroxide. It is a white crystalline powder that dissolves in water. It is often used as a preservative or antioxidant in food products.

Sodium bisulfite is added to foods to prevent browning and preserve color, especially in dried fruits, wines, and processed vegetables. It also acts as a preservative by inhibiting the growth of microorganisms. It is commonly found in canned vegetables, dried fruits, and some processed meats.

The U.S. Food and Drug Administration (FDA) lists sodium bisulfite as Generally Recognized As Safe (GRAS) when used according to good manufacturing practices. However, some individuals, particularly those with asthma, may be sensitive to sulfites and experience allergic-type reactions. 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 acceptable intake levels. Evidence on the health effects of sulfites at typical consumption levels is mixed, with some studies suggesting potential adverse effects in sensitive individuals.
