What it is

Sodium bisulfite is a chemical compound that is a salt of sulfurous acid. It is produced when sulfur dioxide gas is dissolved in a solution of sodium carbonate or sodium hydroxide. It often appears as a white crystalline powder.

Why it's used

Sodium bisulfite is commonly used as a preservative and antioxidant in food. It helps prevent browning in fruits and vegetables, and it can inhibit the growth of bacteria and yeast in foods like dried fruits, wine, and processed potatoes. It is also used to maintain the color and flavor of certain processed foods.

Health notes

In the US, sodium bisulfite is generally recognized as safe (GRAS) by the FDA for use as an antimicrobial agent and antioxidant. It can cause allergic-type reactions in sensitive individuals, particularly those with asthma. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated sodium bisulfite and established an acceptable daily intake. EFSA has also evaluated its safety and established an acceptable daily intake.

Allergen info

Sodium bisulfite is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
