Sodium bisulfite -or sodium bisulphite- -sodium hydrogen sulfite- is a chemical compound with the chemical formula NaHSO3. Sodium bisulfite is a food additive with E number E222. This salt of bisulfite can be prepared by bubbling sulfur dioxide in a solution of sodium carbonate in water. Sodium bisulfite in contact with chlorine bleach -aqueous solution of sodium hypochlorite- will generate heat and form sodium bisulfate and sodium chloride. - Wikipedia

EFSA evaluation: Scientific Opinion on the re-evaluation of sulfur dioxide -E 220-, sodium sulfite -E 221-, sodium bisulfite -E 222-, sodium metabisulfite -E 223-, potassium metabisulfite -E 224-, calcium sulfite -E 226-, calcium bisulfite -E 227- and potassium bisulfite -E 228- as food additives (2016-04-14)

The European Food Safety Authority (EFSA) has determined that some population groups have a high risk of consuming too much E222.
