The discussion of Sulfites has become popular among many of us who suffer from allergies and/or sensitivities to additives in our food.
What is a Sulfite?
A sulfite is a chemical compound generally used as a preservative which can cause some people to have mild to moderate or even severe reactions. Although no foods have a high concentration of sulfites, when combined and consumed on a regular basis, individuals can have moderate to severe reactions to the chemical.
If Harmful Why Are They Used?
In general, sulfites are used as a preservative. They assist in keeping harmful bacteria or fungus from growing in the food products that we consume. Sulfites are used in wine and dried food, acting as an antioxidant to prevent them from turning a brown color. In wine, sulfites also prevent wine from turning into vinegar. They are used agriculturally in many ways to extend the shelf life of products. While most governments have placed a ban on the use of sulfites as a preservative for fresh fruits and vegetables, they continue to be used in preserving dried fruits, making wine, and to preserve seafood and other meats. Sometimes trace amounts can be found in products because of the indirect ways sulfites are used. Most countries do not require labeling of trace amounts of the compound.
