Elemental Trace Analysis in Studies of Food Products

Bromatological, analytical and chemometric assessment of animal and plant foods based on mineral composition

“…flame technique (FAAS), electrothermal (ET-AAS), cold vapor (CV-AAS), hydrogen generation (HG-AAS) as well as Inductively Coupled Plasma -Mass Spectrometry (ICP--MS) and Inductively Coupled Plasma -Optical Emission Spectrometry (ICP-OES). Reliability and correctness of concentration data were checked under the quality assurance test by the use of appropriate certificate reference materials (CRMs) with declared, known concentration of analytes [1][2]. The validated analytical data were then processed chemometrically by means of univariate, bivariate and other multivariate techniques, e.g.…”

“…The aim of multivariate data analysis is to divide data matrix into its components to reduce relatively numerous variables to a smaller number of orthogonal factors. Such approach guarantees achieving a high degree of generalization of registered tendencies or statistical relationships, and what more, at a high level of statistical significance [2][3]13].…”
