dc.description.abstractPlants are widely recognized as a source of several bioactive compounds. Nevertheless, effective decontamination techniques are required to be used by the industry in order to guarantee safety issues. Irradiation is being progressively acknowledged as a feasible conservation methodology, in relation to its high decontamination effectiveness [1,2]. In this work, the effects of irradiation (gamma and electron beam) in nutritional and chemical profiles of Arenaria montana L. (mountain sandwort), a widely used medicinal species in the Caryophyllaceae family, native from the mountainous areas of Southwestern Europe, were evaluated. The nutritional value was determined by official methodologies for food analysis; free sugars were analysed by HPLC-RI, fatty acids by GC-FID, organic acids by UFLC-PDA and tocopherols by HPLCfluorescence. The effects of gamma irradiation and electron beam in the nutritional parameters were similar, except in fat and protein contents. However, regarding the organic acids, while e-beam irradiation did not cause statistically significant changes in any case, gamma irradiation presented significant changes, with a clear tendency to be higher in the irradiated samples. The same occurred in tocopherols content, especially in samples irradiated with 10 kGy. In respect to fatty acids, it was clear that e-beam irradiated samples showed higher relative percentages of SFA and MUFA, while lower values of PUFA. In general, the obtained results might be a good guidance to choose irradiation type or dose according to the need of maintaining a specific chemical or bioactive profile.pt_PT
