ANTIOXIDANT PROPERTIES AND BIOLOGICAL ACTIVITY OF FRUIT WINES
The fruit wines from blueberry were made by microvinification procedure. Wines were produced in the absence or presence of sugar and/or enzymatic preparation glycosidase (EPG). Selected phenolic acids were quantified using UPLC/MS-MS analysis. Total phenolic content (TPC) was determined by the Folin-Ciocalteu method. Also, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing ability of plasma (FRAP) methods were applied. The α-glucosidase inhibitory activity of blueberry wines was also investigated. Wines made with addition of sugar and EPG showed the best results. Phenolic profile and biological activity of blueberry wine depended from microvinification procedure which was used in the production.
