Antioxidant activity and total flavonoid content of honeys
Published December 15, 2010
25-28

The influence of honey on human health has been known since ancient times. Different components, like vitamins, amino-acids, enzymes, and the so called antioxidant activity of the honey play role in this effect, and also in the excellent quality. The aim of present study was to determine the total antioxidant activity and the flavonoid content ...of some honey samples. These two parameters are widely studied, and a lot of data can be used to compare and analyse. On the basis of them we can state that our results are quite similar than those we can find in literature. Characteristic feature of the examined honey samples is, that the antioxidant activity increased with the darkening of the colour. The lowest antioxidant activity and flavonoid content was produced by the acacia honeys with greenish shade of colour. The highest values was found in the very dark honeys (forest, sage, golden rod). The only exception was the coriander honey, where despite of its lighter colour, very high antioxidant activity was
measured.

The effect of collecting area on the element content of Hungarian acacia honeys
Published September 5, 2018
129-138

Six macroelements and twelve microelements were identified in thirty-six Hungarian acacia honeys collected from ten counties by inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). One-Way ANOVA (LSD and Dunnett T3 test) and linear discriminant analysis (LDA) were used to ...determine the statistically verified differences among the honey samples with different geographical origin.

Significant differences were established among the samples from different counties in Na, P, S, Fe, Ni, Cu and Sr concentrations. Based on the macroelement content of honeys, the separation of samples with different geographical origin was not successful because the percent of correctly categorised cases was only 64.9%. However, examining the As, B, Ba, Cu, Fe Mn, Ni and Sr concentration, the separation of different groups was convincing since the percent of correctly classified cases was 97.2%. Thus, the examination of microelement concentration may be able to determine the geographical origin of acacia honeys.
