Unifloral Honeys: Chemical Conversion and Pollen Reduction

Palynological evaluation of selected honeys from Romania

“…Pollen richness depends on the pollen production of the parent plant, the climatic conditions, the distance from the beehive to the flower field, the filtering by the bees' proventriculus and, consequently, the diameter of the pollen grains and the mode of honey extraction (von der Ohe, 1994). If honey extraction takes place by pressing the combs, the pollen stored by the bees to feed the larvae, can pass in to the honey increasing significantly the pollen richness of the honey.…”

Physicochemical characteristics and pollen spectrum of some Algerian honeys

“…Pollen analysis has been the traditional method to determine the floral origin of the honey, but this technique is tedious and has some limitations (Hermosin et al, 2003;Von der Ohe, 1994). Usually, honey is considered unifloral, if the pollen frequency of that plant is >45%.…”

Characterization of Multifloral Honeys of Pervari Region with Different Properties

“…A pollen analysis appeared to be the most frequently used method in such identification studies (Bolchi Serini and Salvi, 1990;Bambara, 1991;Szczcesna and Rybak-Chmielewska, 1993). Pollen characterization and quantification of honeys has been the traditional method to determine the nectar sources and botanical origin, but this technique is tedious and has some limitations (Von der Ohe, 1994;Hermosin et al, 2003). Although (PO) palynological method is important for classifying, it is time-consuming, requires a very experienced analysis and is strongly dependent on the expert's ability and judgment (Piana et al, 2004).…”
