Physicochemical parameters and pollen analysis of Moroccan honeydew honeys

The honeydew elements in 152 honeys from Morocco were studied. The main honeydew indicators are mycelia and fungal spores and, generally speaking, they were found in small percentages. Five mixed or forest honey samples were found by a sediments study, with a proportion of honeydew elements/number of pollen grains from nectariferous species of 1.04–1.83. Their origin (floral or honeydew) could not be confirmed in all cases by physicochemical parameters (pH, mineral content, electrical conductivity, sugars and colour) that were analysed, but recommendations for their characterization are presented.
