Physicochemical Properties of Honey From Different Floral Sources

Abstract

This study was done to investigate the nutritive value of Sudanese bee honey collected from different floral sources (sunut, sidir, talih and sunflower). Physical and chemical analysis were conducted. The results showed significant variation between the different honey types according to the floral origin, which indicate that the level of refractive index ranged from 1.4923 to 1.5038, pH value (4.46 – 5.00), moisture (13.2 – 17.6 %), Ash (0.35 – 0.78 %), protein (0.74 – 1.25 %), ascorbic acid (7.8 – 14.9 mg / 100g), total polyphenols (83.7 – 121.4 mg / 100g), total sugars (76.1 – 81.5 %), reducing sugars (72.6 – 79.3 %), fructose (37.2 – 47.9 %), glucose (25.9 – 40.5 %), sucrose (2.1 – 3.6 %)and free acidity (37 – 63.7 meq / kg). The concentration of minerals in (ppm ) such as potassium were ranged from 1774.5 to 3318.25, sodium (438.90 – 858.70), phosphorus (70.80 – 102.70), iron (39.80 – 50.20), magnesium (17.50 – 37.70), calcium (9.60 – 24.50), manganese (1.95 – 11.70), copper (3.80 – 5.11) and zinc (2.70 – 4.01).
