| Abstract | ||
| Forty-five samples of Egyptian Sidr bee honey were collected from three regions representing the governorates of Luxor, Qena and Sohag in Upper Egypt, during November 2021. Fifteen samples from every Governorate. (five honey samples/ apiary). Honey samples were collected at the rate of 1000 g for this study. All honey samples were provided by professional beekeepers. Evaluation of nineteen physicochemical properties: color, electrical conductivity, density, viscosity, moisture, pH, free acid, lactone, total acid, glucose, fructose, sucrose, maltose, total sugar, glucose/fructose ratio, glucose/water ratio, Hydroxymethylfurfural (HMF), Diastase and Invertase Index. The results showed significant differences in moisture, acidity (PH, free acid, lactic acid and total acidity), fructose and glucose, percentage content in this study between Luxor, Qena and Sohag Governorates. The mean hydroxymethylfurfural content was very low in all Sidr honey samples under study. Invertase activity ranged from 202.69 to 249.85 U/kg. with an overall mean of 225.44± 50.238 unit/kg. honey, diastase activity ranged from 26.59 to 34.19 in both units. With an overall average of 30.41± 10.655 units in both scales | ||
