High resolution mass spectrometry based authentication of Czech and Moravian wines

Popis výsledku v původním jazyce

Nowadays, adulteration of food, beverages and dietary supplements is a growing problem worldwide. Wine is a popular alcoholic beverage and because of its high commercial value, it is one of the most common beverages subject to fraud and mislabelling. Wine may contain hundreds of chemical compounds, their presence and concentrations can be influenced by many factors, such as a grape variety and ripeness, climate and soil of the cultivation area, winemaking techniques and a vintage year. Polyphenols play an important role among the chemical compounds present in wine because of their influence on colour, taste, body, bitterness and astringency. The polyphenolic compounds have also beneficial effects on human health. There are different attributes of wine that can be adulterated (geographic origin, harvest year, etc.). In the last few years, there has been growing interest in developing analytical methods for wine authentication. However, a reliable procedure for the authentication of a wine variety is still unavailable. The aim of this study was to investigate the applicability of profiling of phenolic compounds using ultra-high performance liquid chromatography coupled to high resolution tandem mass spectrometry to authenticate wine according to the grape variety. The metabolic profiling of phenolic compounds based on U-HPLC-HRMS/MS combined with multivariate data analysis, PCA and PLS-DA, was demonstrated to be a reliable tool for wine authentication according to the grape varieties. The most pronounced clustering for grape varieties was achieved for white wines using positive ionization data. Characteristic markers were identified as flavonoids, cinnamic acid derivatives and stilbene derivatives.
