RESUMO

This research deals with the physicochemical, microbiological and pollinic characteristics of 58 samples of Apis mellifera L., 1758 (Hymenoptera: Apidae) honey from the Brazilian states of Ceara (20 samples) and Piaui (38 samples). The following parameters were determined: total sugars, reducing sugars, apparent sucrose, humidity, diastase activity, hydroxymethylfurfural, protein, ashes, ph, acidity, formol index, electrical conductivity, viscosity, color, chemical elements (K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Br, Rb, Sr, Ba, Hg, Pb) and microrganisms. The experiments were set in the "Laboratorio de Insetos Úteis", Department of Entomology, Phytopathology and Agricultural Zoology and in the "Laboratorio de Instrumentação Nuclear, Centro de Energia Nuclear na Agricultura" University of São Paulo, in Piracicaba, State of São Paulo. The results have indicated that most of the mean values for each physicochemical parameter are In accordance with the limits established by the Brazilian the diastase activity is below those limits. Concerning the chemical elements, one observed values above those limits, as follows: Cr, Ni, Zn and Pb. The samples were negative for total coliforms. However fungi and yeast were detected. The pollinic analyses showed that the dominant plant species of the Ceara State were Mimosa caesalpiniaefolia, M. verrucosa, Borreria sp., Serjania sp. and type Fabaceae. The dominant plant species of the Piaui State were Piptadenia sp., M. caesalpiniaefolia, M. verrucosa, Croton urucurana and Tibouchina sp..
