| This study were included quality tests for 12 locally and imported honey samples that available in the markets of Baghdad city. The results showed a variable percentage of moisture, the Hi4 and Hi5 sample recorded 19.9% and 16.4% respectively, the percentage of ash in the Hi2, Hi5, Hi6 and Hi1 samples were 0.4251, 0.3976, 0.3937 and 0.1964% respectively, samples were contained iron, copper and magnesium in varying percents, the highest percentage of iron was 1.7225 ppm observed in Hl10 sample, while the lowest percentage 0.3058 pmm in Hi7 sample, the highest percentage of copper 0.4219 ppm it was found in Hl8 sample, while the lowest percentage 0.0334 ppm in Hl10 sample, and the highest percentage of magnesium 3.9120 ppm was recorded in Hl10 sample, while the lowest percent 1.0056 ppm in Hi7 sample, while all samples not had both of lead, cadmium and cobalt, the value of pH were between 2.6-3.5 Hi3, Hi2 and Hl12 respectively, the results for total acidity were 15.5-18.3 ml. eq./kg Hi3 and Hl12, the samples recorded different degree of polarization, the highest degree 20.71 was observed in Hi1 sample, while the lower degree 8.60 in Hl8 sample, and when determine activity Diastase, we observed the enzyme was active in Hi1, Hi5, Hl8, Hl10, Hl11 and Hl12, while was not as well as in Hi2, Hi3, Hi4, Hi6, Hi7 and Hl9, the results also showed a variation in the total fructose and glucose in honey samples, the highest value 77.6% was recorded in Hl8 sample, but the lowest value 68.4% in Hi1 sample, while the other samples given different percentage, the total fructose and glucose in Hi3, Hi5, Hi6 and Hi7 were 72.9, 70.8, 72.7 and 72.6% respectively, while the total was 74.7, 74.8, 76.8, 75.8, 75.3 and 76.3% in Hi2, Hi4, Hl9, Hl10, Hl11 and Hl12 respectively. | ||
