Oznaczanie wybranych związków bioaktywnych w winach polskiego pochodzenia

Each wine has a unique chemical composition that is influenced by the grape variety, the geology and climate of the vine's growth (terroir), and the winemaking process. Despite the fact that several scientific reports have been published about the characteristic of wines from The Old and The New World Countries, data on the specific characteristics of wines from the cool climate regions is still lacking. The objective of this study was to develop analytical methods for evaluating the quality of domestically produced wines in terms of the concentration of specific bioactive compounds, such as: • organic acids and polyphenols determined in one course of analytical procedure, using solvent extraction of liquid samples through an ultrasound-assisted porous membrane (UASE-PMLS) in conjunction with gas chromatography coupled with mass spectrometry (GC-MS) at the stage of final determinations; • biogenic amines using two analytical procedures (a) capillary electrophoresis coupled with mass spectrometry (CE-MS) and (b) salting-out liquid-liquid microextraction technique coupled with GCMS (SALLME-GC-MS). Furthermore, micro- and macroelements were determined. All the data gathered were used to ascertain the correlations between wines' various physicochemical properties by multivariate statistical analysis. The research work was conducted in accordance with the principles of Green Analytical Chemistry, and the developed methods were assessed for their green nature using the Analytical EcoScale and the GAPI Index.
