Cornflower (Centaurea cyanus L.) honey quality parameters: Chromatographic fingerprints, chemical biomarkers, antioxidant capacity and others

Antioxidant and antiradical properties as well as total phenolic content of the samples were found to be rather moderate by FRAP (ferric reducing antioxidant power), DPPH (1,1-diphenyl-2-picrylhydrazyl radical) and Folin-Ciocalteu assays, respectively. Additionally, CIE L∗a∗b∗C∗h chromatic coordinates were evaluated. Colour attributes of cornflower honey were characterised by elevated values of L∗ and particularly high values of b∗ and h coordinates, which correspond to medium bright honey with intense yellow colour.
