Xanthohumol bound to PVPP
Topics of QuAQuA’s current and recent research:
Electroanalytical analysis, namely square-wave voltammetry, of relevant biological compounds.
Chromatographic analysis of several compounds by HPLC-UV, HPLC-FLD, LC-ESI-MS/MS and GC-MS in several food matrices.
Development of new sampling systems with particular emphasis for volatile and semi-volatile analytes.
Development of new automatic flow-injection analysis (FIA) systems with electrochemical instrumental detection.
Analytical, industrial and biochemical studies of several compounds in beer aiming to improve its routine control, its organoleptic proprieties and to make advancements in brewing science.
Extraction of natural antioxidants from by-products/residues of the food industry and further application in food, cosmetic and pharmaceutical products.
Analytical control of off-flavors in beverages, with particular aim in beer and wine.
Analysis of natural antioxidants and the effects of their presence in food.
Extraction of pectic polysaccharides of different fruits and analytical characterization of its total content sugars by HPLC-UV-FLD, detection and the degree of esterification by GC-FID analysis.
