Sodium metabisulphite is a preservative that inhibits growth of various fungi and other pests and helps preserve content of some vitamins and phytochemicals. It can, however, degrade some vitamins.
Sodium metabisulphite is metabolized easily by the liver to harmless products. In a study of rats fed sodium metabisulphite daily for months, no negative effects were seen.
Individuals sensitive to sulphites should avoid sodium metabisulphite.
