Sulphite is a preservative added to a vast range of foods and beverages to prevent browning or oxidation. Some individuals are sensitive to sulphite additives and may experience a range of allergic reactions. Therefore, both the U.S. Food and Drug Administration (FDA) and European Union (EU) laws require that the presence of sulphites be declared on food labels when the concentration exceeds 10 mg/L. Several analytical methods exist to measure sulphite in food and beverages, however, they suffer from repeatability issues, and can be quite cumbersome to perform. A patent has been filed for an innovative, fast, and accurate ion chromatographic (IC) method based on direct current (DC) mode electrochemical detection. This article explains more.

Organosulphur compounds are important substances in the food industry because they can contribute to the flavour impression of a product. The human olfactory system’s sensitivity to sulphur leads to low flavour threshold values, making the analysis of these substances a challenging task. Gas chromatography (GC) with sulphur chemiluminescence detection (SCD) is a highly sensitive and selective technique for the analysis of sulphur compounds in various matrices. Using a range of different beers as an example, an approach is presented to reliably qualify and quantify sulphur components in beverages using headspace sampling and GC–SCD.
