Sodium Metabisulfite Mono- And Diglycerides

Sodium metabisulfite is a white or slightly yellowish crystalline powder. It is a salt of sulfurous acid, formed by reacting sulfur dioxide with sodium carbonate or sodium hydroxide. It is often used as a preservative and antioxidant in food products.

Sodium metabisulfite is used as a preservative and antioxidant. It helps prevent spoilage by inhibiting the growth of bacteria and fungi, and it can also prevent browning in fruits and vegetables. It is commonly found in dried fruits, wines, and processed potatoes.

In the U.S., sodium metabisulfite is generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. It can cause allergic reactions in some individuals, particularly those with asthma. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated sodium metabisulfite, and both have established acceptable intake levels. Evidence on its long-term effects at typical consumption levels is generally reassuring, but sensitive individuals should be aware of potential reactions.
