Evaluation of antioxidants in currant and gooseberry

Original language description

Regular fruit consumption helps to strengthen human health by protecting cells from damage by free radicals. Berries of soft fruit contain large quantities of substances with antioxidant activity. The method of Flow Injection Analysis with electrochemical detection for determination of antioxidant activity of soft fruits grown in organic regime (EKO) in comparison to the integrated pest management orchard (IPM) was used. Antioxidant activity was expressed as electrical charge in C (Coulombs) per gram fresh weight of fruits. In total, 49 samples of currant cultivars (red, black, white and pink) and 18 samples of gooseberry cultivars (red and white) were measured. Differences in antioxidant activity between the cultivars were observed, where cultivars with darker fruit reached higher values. The highest antioxidant activity was found in cultivars of black currants, lower in red currants and the lowest in white gooseberries. The highest antioxidant activity was determined among currants for the cultivars ‘Triton’ from the group of black currants (EKO; value 0.785 C g-1), for cultivar ‘Jesan’ (IPM; value 0.226 C g-1) from the group of red currants and for ‘Blanka’ (EKO; value 0.356 C g-1) from the group of white currants. The highest antioxidant activities among gooseberry cultivars were determined in red gooseberries for cultivar ‘Karmen’ (EKO; value 0.117 C g-1) and in white gooseberries for cultivar ‘Mucurines’ (EKO; value 0.045 C g-1). The higher antioxidant activity was determined both for currants and gooseberries grown in EKO in comparison to IPM.
