What it is
Sodium sulfite is a white crystalline powder. It is a salt of sulfurous acid, which is formed when sulfur dioxide gas dissolves in water. It can be produced industrially by reacting sulfur dioxide with a sodium base, such as sodium carbonate or sodium hydroxide.
Why it's used
Sodium sulfite is used as a preservative and antioxidant in food. It helps prevent browning in dried fruits and vegetables, and it inhibits the growth of bacteria and mold in some foods. It is also used in winemaking to prevent oxidation and spoilage.
Health notes
In the US, sodium sulfite 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 sulfites, and they are permitted for use in many countries.
Allergen info
Sodium sulfite is not derived from any of the nine FDA major allergens. It does not contain gluten.
