Using melissopalynology, only a small amount of pollen was found in the filtered honeys, as expected. About 90% of pollen amount were lost after filtration.
Colour is an important quality parameter of honey. It results from the desirable yellow component and the undesirable brown component. The tristimulus colour system CIELab was used to record the colour parameters of the unfiltered and filtered honey samples. The L∗ is the measure of the brightness (lightness) from black (0) to white (100). The a∗ is the function of the red-green difference. Positive a∗ indicates redness, whereas negative a∗ indicates greenness. The b∗ is the function of the green–blue difference. Positive b∗ indicates yellowness, whilst negative b∗ indicates blueness. The units within the L∗, a∗, b∗ system give equal perception of the colour difference to a human observer. The average L∗, a∗, b∗ values of the honey samples of different types are presented in Table 2.
