Effect of filtration on colour, antioxidant activity and total phenolics of honey

82 Honey samples harvested in 2009 and 2010 flowering seasons were investigated in order to examine the influence of filtration on colour, antioxidant activity and total phenolics content. In unfiltered honey samples the total phenolics content varied between 40.5 and 177 mgGAE/100 g. The average antioxidant activity ranged from 47.2 to 83.4% when measured with DPPH and from 6 to 79% once measured with ABTS+. The results indicated that filtration had no significant effect on the above-mentioned parameters, however they were found to depend on the types of honey.
