The potential of selected ion flow tube mass spectrometry (SIFT-MS) to differentiate malted barley cultivars on the basis of their headspace profiles has been investigated. Prime focus is on the analysis of aldehydes and particularly as compared to the headspace SPME GC-MS method currently used. Whereas GC-MS is the technique of choice for detailed analytical volatile fingerprinting, it is not suited for real-time quantitative monitoring. In this respect, the SIFT-MS technology is fully complementary to GC-MS for quality control of raw materials, fast evaluation of worth, and monitoring fermentation.
