Physicochemical characteristics and pollen spectrum of some Algerian honeys

The characterisation of Algerian honeys was carried out on the basis of the microscopic (pollen analysis) and physico-chemical properties. The samples were analysed for parameters including refractive index, moisture, density, dynamic viscosity, pH, specific rotation, electrical conductivity, ash, sugars, proteins, proline and phenolic compounds contents. The results obtained in the present study show the variability of chemical composition of the honey samples. The botanical families Myrtaceae, Apiaceae and Ericaceae are most frequently found. The most pollen types are Eucalyptus which is present in five samples. The samples are found to meet national and international honey specifications. © 2005 Elsevier Ltd. All rights reserved.
