【 摘 要 】

Some physicochemical properties (water content, sugar content, viscosity, pH and conductivity) were determined for honey samples from North-Central Nigeria to evaluate their globalbehaviourand comparison with other honey samples. The water content and sugar content varied within the range of (18.22 - 36.82%) and (63.82 - 80.25%) respectively. The pH increased with increase in water content and the conductivities of the samples had correlation with proportion of minor constituents in the honey samples. The relationship among water content (w), temperature (t) and viscosity (η) for different honey samples of may be represented as η = 17.678× 103exp (-0.32w - 0.088t). The temperature dependence of viscosity was evaluated with Arrhenius model, theactivation energy with value of 70.07 kJ/g is fairly unaffected by moisture content.
