Samples
82 Honey samples of different botanical and geographical origin (Table 1) were analyzed to evaluate the effect of filtration on selected quality parameters. The unprocessed samples, bought directly from beekeepers, were harvested during 2009–2010 flowering season. Each sample was available in unfiltered and originally filtered form to compare the honeys directly. 50–100 g of each sample were rapidly warmed to 45 °C (5–10 min), mixed thoroughly and filtered out with Schott filters (Duran, Mainz, Germany), pore size < 40 μm, under the pressure of 0.3–0.4 MPa. Afterwards, the honey was cooled down. Sample extraction was carried out directly before and after the filtration. The result of filtration was confirmed by pollen analysis.
