Abstract

The present study was carried out in Economic Entomology Department Faculty of Agriculture, Mansura University, to evaluate some physical properties (Moisture, Total soluble solids, Electrical conductivity, Viscosity and specific gravity) and some chemical properties (Ash, PH, Free and Total acidity, lactone, Hydroxy methyl furfural, diastase activity and Sugars) of Egyptian and Iraqian honeys according to Egyptian honey standard (2005) and Iraqian honey standard (1984). All analysis were carried out in laboratories – Faculty of Agriculture – Mansoura and Cairo University, in addition to Bee Researches department, protection Research Institute. In relation to Egyptian honeys, tested nine samples taken from six governorate ( Giza, Al-Dakhlia, Al-Sharkia, Al-Behira, Ismalia and Kafer El-Sheikh). Also, nine Iraqian honey samples were taken from four governorate (Arbil, Baghdad, Diyala and El-Anbar ). The study included, determination pollen grains in Egyptian and Iraqian honeys.The moisture content divided into three groups: the first groups include eight samples characterized by its distinctive low moisture content 18% or less (from 18% to 16%).Viscosity values ranged between 13.60 to 69.00 poise in Egyptian honeys, while between 48.1 to 87.5 poise in Iraqian honeys.According to results, it was found that all Egyptian honey samples (PH values) were accepted from Egyptian honey standard and refused from Iraqian honey standard. All Egyptian honeys were accepted from Egyptian honey standard., while it was found one honey sample C2 refused from Iraqian honey standard. All Iraqian honey samples were accepted by the Iraqian honey standard, while two Egyptian honey samples (clover A2 and citrus B2) refused from Iraqian honey standard. According to the data of diastase number, seven Egyptian honey samples were accepted from Egyptian standard, while two samples (clover A2 and citrus B3) refused by Egyptian standard and recorded 2 and 2.61 DN, respectively. Seven Egyptian honey samples were accepted from the Egyptian standard (2005) in relation to sucrose and only two samples (clover A2 and cotton C1) refused, recorded 10.87% and 10.97% and this attributed to be attendance of sugars agriculture wastes. In relation to pollen types in Egyptian honey samples were: clover, Eucalyptus and citrus in clover honey, citrus, Eucalyptus, Casuarina, olive, apricot in citrus honey and maize and Purslane in cotton honey. The results indicated that it was not found significant difference between Egyptian and Iraqian honeys in relation to moisture percentages. It not found significant differences between Egyptian and Iraqian honeys in relation to total soluble solids (TSS).The obtained results cleared that low significant differences between Egyptian and Iraqian honeys in relation to electrical conductivity (EC).The results indicated that it found low significant differences between Egyptian and Iraqian honeys in relation to viscosity.there was in significant differences between Egyptian and Iraqian honeys in relation to specific gravity. It was found low significant differences between Egyptian and Iraqian honeys in relation to total acidity values.It was found low significant differences between Egyptian and Iraqian honeys in relation to ash content. In relation to hydroxy methyl furfural it was found low significant differences between Egyptian and Iraqian honey samples. According to diastase activity it was found low significant differences between Egyptian and Iraqian honey samples. The sucrose content in Egyptian and Iraqian honeys is mostly in accordance with the other international standards.
