Antioxidant Activities and Total Phenolics of Acacia Honey [PDF]

open access: yesCzech Journal of Food Sciences, 2009
The antioxidant activities and total phenolic content of 30 samples of acacia honey from Croatian territory were analysed. Phenolics were determined by the modified Folin-Ciocalteu method, antiradical activity by the 1, 1-diphenyl-2-picrylhydrazyl (DPPH) method and potential antioxidant activity using the ferric reducing antioxidant power (FRAP) method.
