What it is

Sulfiting agents are compounds containing sulfur dioxide. They occur naturally in small amounts in some foods and are also produced by the body. Industrially, they are often produced from sulfur dioxide gas.

Why it's used

Sulfiting agents are used to prevent browning and preserve food by inhibiting the growth of microorganisms. They are commonly found in dried fruits, processed potatoes, and some baked goods, as well as in wine and beer.

Health notes

Sulfiting agents are generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. However, some individuals, particularly those with asthma, may experience sensitivity reactions. The WHO/IARC has evaluated sulfites, and EFSA has also reviewed their safety. Evidence on the extent and mechanisms of sulfite sensitivity is still being researched.
