Chemometric and multielement techniques for the exploratory analysis of honey q...
Rios, Francisco Teodoro; Lobo, Manuel Oscar; Castanheira, Isabel; Delgado, Inês; Nascimiento , Ana; Sammán, NormaThe proximal and mineral profiles of multi floral honeys from different geographic regions were determined and related to their origin. Moisture, °Brix sugars, ash, pH, free acidity, water activity (aw) and minerals content were determined by AOAC methods. In the exploratory analysis, non-supervised chemometric methods were applied to build classification rules and relate the origin of the samples based on thei...

The Impact of Various Types of Cooking on the Fate of Hg and Se in Predatory Fi...
Ribeiro, Mariana; Douis, Laurène; Silva, José Armando Luísa da; Castanheira, Isabel; Leufroy, Axelle; Jitaru, PetruThis study addresses the effect of various cooking approaches on total Hg (HgT) and total Se (SeT) contents in three predatory fish species. For this purpose, samples of swordfish, dogfish, and tuna from regular French (fish) markets were cooked by boiling, steaming, grilling, and frying, respectively. The levels of HgT and SeT in raw and cooked samples were determined by inductively coupled plasma-mass spectro...
