Ham quality evaluation assisted by gas chromatography ion mobility spectrometry. Isoen 2017 - Isocs/Ieee International Symposium On Olfaction And Electronic Nose, Proceedings, 2017, 7968852-NAhttps://hdl.handle.net/2445/188027In recent years, Gas Chromatography-Ion Mobility Spectrometry (GC-IMS) has been successfully employed in food science as a control technique for the prevention of fraud according to food and labeling regulations. In this work, we propose the use of GC-IMS technique to assess the quality of Iberian ham with regard to the Iberian Pig's diet (either nourished with feed or with acorns). For this purpose, we have acquired a dataset composed of 53 samples of Iberian ham from different food providers using a commercial GC-IMS (FlavourSpec, from G.A.S. Dortmund, Germany). Intensive signal pre-processing for GC-IMS was applied to the raw data. This dataset was employed to create four Partial Least Squares Discriminant Analysis (PLSDA) models corresponding to different train/test partitions of the dataset. Nearly perfect classification rates (above 91 %) were obtained for each partition of the dataset, denoting the high power of GC-IMS to characterize food samples. © 2017 IEEE.3 p.application/pdfeng(c) IEEE, 2017Tecnologia dels alimentsControl de qualitat dels alimentsPernilCromatografia de gasosFood technologyFood quality controlHamGas chromatographyGC-IMSPLSDAinfo:eu-repo/semantics/other2022-07-19info:eu-repo/semantics/openAccess6466923
