Challenges in the Analysis of Soft Drinks

Techniques involving mass spectrometry (MS) as a detection tool in food analysis have evolved substantially. Gas chromatography–mass spectrometry (GC–MS) and liquid chromatography–mass spectrometry (LC–MS) are commonly used to detect, identify, quantify and confirm both natural and xenobiotic substances in the food production chain. One of the most distinctive trends in MS-based analysis is the use of time-of-flight mass spectrometry (TOF-MS) for both target and non-target analysis of a wide range of organic compounds that occur in biotic matrices. High-speed unit resolution TOF-MS instruments can be combined with a fast one-dimensional GC and/or comprehensive two-dimensional GC (GCGC) set-up with “flash ” separation in the second dimension to identify and quantify a wide range o
