Study of Physicochemical parameters and Antioxidant in Honey collected from different locations of India

Abstract

Four varieties of honey collected from the different regions of India for the investigation of physicochemical and antioxidant. The study revealed that all the samples showed pH, Moisture,  EC, TDS, HMF, Colour intensity, total sugar, reducing sugar and sucrose range (3.30-4.13,  15.69-17.23%, 152.33-371.66 µS/cm, 101-241.33 mg/l, 1.75-27.87 mg/Kg, 106.60-1592 mAU,  64.88-73.08%, 62.24-70.24% and 1.76-2.58%) respectively. Among the variety polyflora forest  (PFf) is the best showing pH (4.13 ± 0.02), Moisture (17.23± 0.01%), Electrical Conductivity  (EC, 371.66 ± 0.68 µS/cm), Total Dissolved Solids (TDS, 241.33 ± 0.68 mg/l), Hydroxyl Methyl  furfural (HMF, 1.75 ± 0.00 mg/Kg), Colour intensity (1592.00 ±2.93 mAU) and total sugar,  reducing sugar and sucrose contents were 65.03 ± 0.05 %, 62.24 ± 0.29 % and 2.25 ± 0.09 %  respectively. Even PFf showing minerals Ca, Mg, Na, K, Fe, Zn and polyphenol (2119.28 ± 0.34  mg/Kg), flavonoids (975.50 ± 0.24 mg/Kg), flavonols (588.30 ± 0.33 mg/Kg), flavones (387.26  ± 0.22 mg/Kg) content was found to be more than monoflora, polyflora and processed one.  Compare to other varieties PFf extract was markedly a more potent DPPH free radical scavenging activity and reductive Capacity. From this it concluded that the honey PFf variety was the best than the remaining.
