Comparative Study on the Compositional Analysis of Honeys Produced in South-South Region, Nigeria

Abstract

This study investigate the compositional analysis of honey samples  obtained from six  states (Edo, Delta, Bayelsa, Rivers, Cross River and Akwa Ibom) in south-south region, Nigeria. The compositional  parameters of the honey that were examined includes; moisture content, ash content, pH, refractive index, viscosity,  potassium, magnesium, calcium, iron and glucose. The range of results for the six  states are as follows; Moisture content (12.43%  - 28.33%); Ash content (0.093– 0.86)g 100g^‑1 ; pH value (3.1 – 4.6); Refractive index @ 20^oC (1.4663 – 1.5064); Viscosity @ 20^oC (2.372 – 3.814) cP; Glucose (30.14 - 43.12%); Potassium (4.78 – 8.06) ppm; Magnesium (0.97 – 1.98) ppm; Calcium (0.43 – 0.51) ppm and Iron (2.49 – 7.16) ppm. The mean and standard deviation of the parameters for the six  states are as follows: Moisture content (19.84 ± 5.79); Ash content (0.57 ± 0.31); pH value (3.91 ±0.63); Refractive index @ 20^oC (1.49 ±0.015); Viscosity @ 20^oC (3.142 ± 0.5254); Glucose (39.06 ± 5.00);  Potassium (5.84 ± 1.16); Magnesium (1.43 ± 0.41); Calcium (0.47 ± 0.027) and Iron (5.76 ± 1.79). There is a significant difference in the properties of the honey with respect to locality at p < 0.05.The results of analysis shows that the studied parameters were within recommended limits with the exception of moisture and pH which recorded values beyond the maximum recommended limits for some of the studied samples.
