| Abstract | ||||
| A total of 24 honey samples from eight different botanical sources were analysed. Results are presented for : specific gravity, viscosity, colour, electrical conductivity (EC) "/6 and total solids "/o. Moisture ”fa, pH, free acidity mgfkg, Lactone (mail-cg), total acidity (mqfkg), Proline mgitUUgm and hydroxy methyl foriurai (H.M.F.). The results of physical properties showed that the specific gravity was parallel aznd ranged from (1.39 - 1.42). The viscosity ranged from (13.6 - 46.1 poise). the color ranged from (0.02 . 0.36 ppm), the electrical conductivity (Ec) ranged from (110 - 520 ppm), whereas the total soluble parallel and ranged from (T9 - 81759:.) The results of chemical compsotion showed that the moisture ranged from (17 - 21%), the pH value ranged from (3.? - 4.?) The total acidity content is parallel and ranged from (16.5 - 86%) molt-(g, the proline content ranged from (31.6 - 56.6 mgfIUG gm). The HMF content ranged from (2 - 23.04 mgfkg) in the different types of tested honeys. From data obtained it is clear that the biochemical variation can be useful separating at least some different honeys within different types. Discriminant analysis was used to distinguish honeys, using eight variables for 24 samples (eight plant sources). From data obtained it was found that the most useful characteristics were electrical conductivity, HMF, free acidity and Proline content. | ||||
