Consumer Advice
Sodium hydrogen sulfite (also called sodium bisulfite) is a sulphite preservative and antioxidant used in fruit wines, dried fruit, juices and pickled vegetables to prevent browning and microbial growth. It acts by releasing sulfur dioxide. As with other sulphites, it is safe for most people, but sulphites are a legally declared allergen and asthmatics or sensitive people should be alert. Residues in compliant products are tightly regulated, so buying from reputable sources is sufficient.
