In the present experiment, the significance of cultivar (convention-al and coloured) and of the application of the soil fertility enhancer UGmax on health-promoting properties of carrot roots subjected to the freezing process of carrot cubes after water blanching was investigated. The selection of cultivar turned out to be highly signif-icant with respect to the development of health-promoting properties of carrot roots. The highest antioxidant properties were found in the purple cultivar ‘Deep Purple’. Its mean antioxidant capacity accounted for 5.31 mmol Fe+2 · kg–1 f.m. Essential for health-promoting properties were the contents of anthocyanins (R2 = 0.83), chlorogenic acid (R2 = 0.81) and total polyphenolics (R2 = 0.71). The application of the biological agent UGmax improved the qual-ity of carrot significantly, increasing the content of total carotenoids and reducing the losses of ascorbic acid during processing. The freezing process negatively influenced the antioxidative properties of carrot irrespective of cultivar and applied agro-technique (use of UGmax), especially in the case of water-soluble antioxidants such as anthocyanins and ascorbic acid
