With Sodium Metabisulfite

Sodium metabisulfite is a white or slightly yellowish crystalline powder. It is a salt of sulfurous acid, formed by combining sulfur dioxide with sodium carbonate or sodium hydroxide. It is commonly produced industrially through chemical synthesis.

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

In the US, sodium metabisulfite is generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. It can cause allergic-type 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 daily intakes. Some people are sensitive to sulfites and may experience adverse reactions.
