| Brachystegia eurycoma (BE), Afzelia Africana (AA) and Mucuna solannie (MS) flours were blended (%, w/w) at varying proportions: 50:50, 60:40, 70:30, 80:20 and 100:0, with 100% of flours as the control; then analyzed based on the phyto-chemical, functional and proximate compositions. Tanin, saponin, alkaloid and flavonoid values were 4.19, 1.47, 1.49 and 1.15 mg 100 g-1 dm; 3.44, 0.45, 1.34 and 1.13 mg 100 g-1 dm; and 4.1, 0.61, 1.36 and 1.18 mg 100 g-1 dm in MS, AA and BE flours respectively. Increased AA and BE proportions in MS flour increased the swelling index (1.49% -1.76%) whereas AA and BE inclusions (%) resulted in significant () increase in the moisture content of the composite flours (8.3- 14 %). Increase in % AA flour inclusion resulted in... |

| This study determined the effects of temperature and time on oil extraction from indigenous freshwater microalgae– Dictyosphaerium, Chlorella, Desmodesmus and Cosmarium species, cultured in fifteen 2-litre column photobioreactors (PBR) (three per specie). Growth and specific growth rates for the mixotrophic>autotrophic cultivation of the species. Oil was extracted from the dried microalgae species at temperatures ranging from 40 to 120 °C at 20 oC intervals and times ranging from 30 to 210 minutes at 30 minutes’ intervals, by accelerated solvent extraction method. Extraction temperature, time and type of microalgae species had significant effect (p < 0.05) on oil yield (temperature > time > type of species). As extraction temperature and time... |

| The effects of floral location on the physicochemical and thermal parameters of honey samples from Enugu North senatorial zone were evaluated. Floral location had significant effects (P 0.05) on viscosity, electrical conductivity, sugar content, free acidity, ach content, moisture content, density, pH, colour, thermal heat conductivity and thermal heat diffusivity except, F/G ratio and specific heat capacity. Honeys from Igbo-Eze South were more viscose than the rest of the honey samples from other floral locations, with a mean viscosity value at 25 oC (15.58cSt) higher than that at 60 oC (12.63cSt). The electrical conductivity, ash content, moisture content and density ranged between 226.5 - 211.45 µS cm-1, 0.06 - 0.57%, 16.59 – 22.55% and 0.82 – 1.25 g... |
