This paper describes a novel approach to determine the individual contribution of volatile compounds to the overall sensor responses of metal oxide semiconductor (MOS) sensors when they are applied to a complex mixture of compounds such as food aroma. A methodology entailing the use of a sensor array or electronic nose (EN) as non-destructive detector in-parallel with the flame ionization detector...
In this study, we intend to develop a simple and selective procedure to extract compounds involved in the strong odour which appears after fenugreek ingestion (this odour is responsible of the so-called pseudo-maple syrup urine disease). Two procedures, solvent extraction and headspace solid-phase microextraction (HS-SPME), were employed to extract compounds from armpits sweat samples collected from...
