Sulfites are compounds containing the sulfite ion, most often in combination with sodium (sodium sulfite) or potassium (potassium sulfite). Sulfites release the irritant gas sulphur dioxide, which acts as a preservative and bleaching agent. As well as occurring naturally in some foods and in the human body, sulfites are added to certain foods to act as a preservative as they inhibit microbial growth, maintain food colour and increase shelf life.
Foods to which sulfites are commonly added include wines, beer and dried fruit. They are also used to bleach food starches, such as potato starch and are used in the production of some food packaging materials such as cellophane.
