And Sodium Bisulfite

Sodium bisulfite is a chemical compound that is a salt of sulfurous acid. It is a white crystalline powder that is soluble in water. It is produced industrially by passing sulfur dioxide gas through a solution of sodium carbonate or sodium hydroxide.

Sodium bisulfite is used as a preservative and antioxidant in many foods. It helps prevent spoilage by inhibiting the growth of bacteria and fungi, and it also prevents browning in fruits and vegetables. It is commonly found in dried fruits, processed potatoes, wine, and some baked goods.

In the U.S., sodium bisulfite 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, including sodium bisulfite, and established acceptable daily intake levels. Some people are sensitive to sulfites and may experience adverse reactions.
