Sulphur Dioxide and Sulphites
Sulphur dioxide and sulphites are used in food as an additive for conservation (E220-E228). Intolerance reactions are similar to an allergic reaction, so called pseudoallergic reactions, and are often triggered by food additives. Concentrations of sulphur dioxide of more than 10 mg/kg respectively 10 mg/L are therefore subject to labelling requirements in Europe for consumer protection.

Method of Determination
Whether dried fruits, grapes or potatoes - at GALAB we routinely determine sulphite and sulphur dioxide using titration after distillation (expressed as SO2).
