Physicochemical, Microbiological and Sensory Properties of Honey from Yewaland, South-West Nigeria

Consumers are concerned about the authenticity and general quality of honey in Yewaland, Nigeria. Physicochemical (moisture, protein, ash, fructose, sucrose contents; total titratable acidity, total soluble solids, specific gravity, viscosity, electrical conductivity, refractive index and pH), microbial tests (total plate and identification), and sensory properties of honey samples were evaluated. Samples were collected from bee breeders in the different areas of the region. The results ranged from 13.6-15.0% moisture, 0.2-5.2% protein, 0.24-0.38% ash, 40.5-45.6% fructose, 3.0-5.8% sucrose, 1.40-1.47 specific gravity, 1607-2037 viscosity, 6.3-14.9
S/cm electrical conductivity, 40.3-75.5mg/l total soluble solids, 3.60-4.2 pH, 0.39-0.46 titratable acidity and 1.34-1.35 refractive index. Staphylococcus, shigella, and Bacillus spp were identified in some samples. The appearance of the samples was lighter. Samples from Oja-Odan and Iwoye had the best overall acceptance scores of 8.7 and 8.5 respectively. Thus honey samples were of good quality compared to the international standard and their acidic pH values reveal that they are unadulterated and have good shelf stability potentials. Their characterization will make it possible to obtain Nigerian quality labels.
