Is Sodium Metabisulfite Allowed to Be Added to Food?


Sodium metabisulfite used in food is safe within the national quality standards.

Sodium metabisulfite is a kind of food additive, which is generally used as an antioxidant, preservative and bleach. As long as used within the specified range and dosage, it will not have any impact on human health. Therefore, China plans to expand the use range of sodium metabisulfite to allow its use in Lamian Noodles.

On February 17, the Ministry of Health issued the No. 2 announcement of 2013, approving the expansion of the use scope and dosage of 10 food additives such as vitamin E and Sodium metabisulfite. Among them, sodium metabisulfite can be used as an antioxidant in wet noodle products (only Lamian Noodles), with the maximum use amount of 50 mg/kg (based on sulfur dioxide residue).
