foods containing sulphites
Sulphites are used as food preservatives to prevent microbial spoilage. They also act as anti-oxidants to prevent lettuces and other fruits and vegetables from turning brown. After a sulphite treatment, vegetables maintain their fresh appearance even though they may be quite old and stale. They are also used to sanitize containers in the fermentation industry. Restaurant meals may contain up to 25-100 mg of metabisulphite in one meal.
There are actually six sulphiting agents. These are sulfur dioxide, sodium sulphite, sodium bisulphite, potassium bisulphite, sodium metabisulphite, and potassium metabisulphite.
