Differential mobility spectrometry coupled to mass spectrometry (DMS−MS) for the classification of Spanish PDO paprika

# metadata.dc.description.abstract[].value
Ion mobility spectrometry (IMS) has proved its huge potential in many research areas, especially when hyphenated with chromatographic techniques or mass spectrometry (MS). However, focusing on food analysis, very few applications have been reported following a fingerprinting approach. Therefore, in this study, differential mobility spectrometry coupled to mass spectrometry (DMS−MS) is presented for the first time as an alternative technique for food classification and authentication purposes using a fingerprinting strategy. As a study case, 70 Spanish paprika samples (from La Vera , Murcia , and Mallorca ) were analysed by DMS−MS to address their classification ¿using partial least squares regression-discriminant analysis (PLS-DA)¿ and authentication ¿through soft independent modelling of class analogy (SIMCA)¿. As a result, after external validation, complete sample classification according to their geographical origin and excellent La Vera and Mallorca sample authentication were reached.
