With Sodium Metabisulfite Retention

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

Sodium metabisulfite is added to foods to prevent spoilage by inhibiting the growth of bacteria and molds. It also acts as an antioxidant, preventing browning and preserving the color of foods. It is commonly found in dried fruits, wines, and processed potatoes.

The FDA lists sodium metabisulfite as Generally Recognized As Safe (GRAS) when used according to good manufacturing practices. It can cause allergic reactions in some individuals, particularly those with asthma or sulfite sensitivity. JECFA and EFSA have evaluated sulfites, including sodium metabisulfite, and have established acceptable daily intakes. While generally considered safe, excessive intake can lead to adverse effects.
