Analysis of Sulfites in Food and Beverages Using Single Quadrupole Mass Spectrometer


User Benefits

- The development method provides rapid analysis of sulfites, which are added to various foods and beverages as antioxidants. - Good quantification was achieved with the method based on the U.S. FDA method (C-004.03). - The safety of pre-treatment protocols can be offered without the use of dichloromethane as a specified chemical substances.


Sulfites are one of the most common food additives used as antioxidants and bleaching agents, and they are added to various products such as dried fruit, vegetables, frozen shrimp, juice, or wine. Although sulfites are very useful food additives, it is known that consuming food or beverages containing them can cause reactions like allergies. Therefore, the U.S. Food and Drug Administration (FDA) requires the labeling of foods containing more than 10 mg/kg of sulfites, and they have also issued a quantitative analysis method for sulfites. In application news No. 01-00450-EN, we introduced an example of quantitative analysis of sulfites in food and beverages using a triple quadrupole mass spectrometer, referring to the analysis method proposed by the FDA. Meanwhile, a new method is introduced in this application, which can offer preprocessing without the use of dichloromethane as specially regulated substance and simplified quantification analysis of sulfites using LCMS-2050.
