Oils of Jatropha curcas and Helianthus annuus stored at ambient conditions for four months in four different containers (polythene, glass, metal and plastic bottles) were sampled at one month interval for physico-chemical properties. Increases were noted in all the containers as follows: Free fatty acid (0.72-1.02 and 0.6-1.14%), peroxide value (0.2-1.86 and 0.23-0.44 mEq kg-1), iodine value (1.40-11.50 and 6.20-14.20), acid value (13.00-50.00 and 36.00-59.00 mg KOH g-1) for Jatropha curcas and Helianthus annuus, respectively. No container effect on the color, dirt/sediment, specific gravity and reflective index of the oils was apparent. All parameters were closed in the limits for oils edited by Codex Alimentary Commission. |

The proximate composition, mineral, physical characteristics and in vitro digestibilities of cucumber (Cucumis sativus) were determined using standard methods of analysis. The results revealed that the mesocarp, epicarp and endocarp of the cucumber contained: 1.68, 3.84 and 0.22% of protein, respectively. The relative fat content varied from a low of 0.02% in endocarp to a high of 0.56% in epicarp, moisture and ash contents were comparable with values of literatures cited. As expected macro minerals were higher than the micro minerals. Na had the highest value followed by Mg, K and Ca. Pb was not detected. In vitro digestibilities of the samples were determined for 10 min. Percentage digestibilities varied thus: epicarp (68.5) mesocarp (78.2) and endocarp (80.5). From the obtained results, it was observed that epicarp of the sample had higher values for ash, protein, fat, fiber and carbohydrate than mesocarp and epicarp. It is hoped that these results would add to existing nutrition data. |

Cockroach, earthworm and soldier ants were analyzed for their proximate compositions, minerals and phytate contents. Values for proximate composition ranged thus: cockroach (protein 9.26%; fat 21.21%; fibre 7.52%; ash 6.85%; moisture 13.85% and carbohydrate 41.33%; earthworm (protein 50.22%; fat 8.62%; fibre 1.36%; ash 26.56%; moisture 8.53% and carbohydrate 4.73%; soldier ants (protein 12.09%; fat 18.92%; fibre 20.13% ash 8.54% moisture 12.62% and carbohydrate 27.72%. Calcium was the most abundant mineral present while Cd was not detectable. The levels of phytate and phytate phosphorus were high and the samples had more than 30% of their total phosphorus linked to phytate. The Ca: Phytate molar ratios of the samples were relatively low. Based on the results it is suggested that nutritional potentials of cockroach, soldier ants and earthworm should be harnessed for use in animal feed formulation. |

The aim of this study was to assess nutrient values of lizards (Agama agama). The samples earmarked for this study were obtained at Federal College of Agriculture, Akure, Nigeria. In male and female Agama agama lizards, anatomical weights, proximate and mineral contents, tannin, oxalate and phytate compositions were determined using standard methods. The samples contained: 54.05-57.69% protein; 2.56-3.01% fat, 1.11-3.18% fibre, 12.91-13.40% ash, 21.38-21.94% NFE, 3.85-4.18% moisture and 328.80-347.5 kcal energy. All the major elements determined were found to be high. The tannin, oxalate, phytate contents were low, meaning that the bioavailability of protein and minerals are high. The values recorded for proximate and minerals compared with other animal sources. It is recommended that nutritional qualities of lizards should be harnessed. |

Studies were carried out on scorpion (Androctonus australis) to investigate its proximate composition, mineral content, oxalate, tannins and phytate. The sample was washed, sieved, dried and finally milled to flour before analysis. The sample may serve as weaning protein source and contained 52.91% protein. The predominant metal was potassium (695.21 mg kg-1) and cobalt found only in traces (2.50 mg kg-1). The anti-nutrient ranged as follows. Tannin (0.24%), phytate phosphorus (2.09 mg g-1), phytate (7.41 mg g-1) and oxalate (0.72 mg g-1). On average, a serving (100 g) of milled, scorpion sample guarantees 331.55 kcal of the daily recommended energy. The phytate, tannin and oxalate contents are of nutritional significant they form insoluble complexes with proteins and minerals. |

The effect of palm oil for the control of Sitophilus zeamais and Callosobruchus maculatus in stored grains was investigated using standard methods of analyses. The experiment was conducted between May and October 2006 in Chemistry laboratory of the Department of General Studies, Federal College of Agriculture, Akure, Nigeria. The quantity of oil used for the storage of 25 g of Zea mays, Cajanus cajan and Vigna unguiculata was 0.1, 0.2, 0.3 and 0.4 mL each. The results showed that the rate of mortality of S. zeamais and C. maculatus was high using 0.3 and 0.4 mL of palm oil. There was no sign of oviposition during the storage except in the control. The result also showed that the higher the quantity of oil, the lower the number of exit holes. Seed viability in the test was high compared to the control which did not show any sign of viability i.e., seed viability was not affected by the oil treatment. The application of the oil on the stored grains was simple and the results were encouraging. Efforts should be made to encourage its use in pest management. |

The physico-chemical and trace metal contents of water samples from Akure, Nigeria were assessed using atomic absorption spectrophotometery. Results indicated that low variation existed among some physico-chemical parameter (pH, temperature, conductivity, dissolved oxygen and nitrate). In the water sample oil and grease, taste and odor were not detected. The mean levels (mg L-1) of the metals ranged thus; 4.8(Fe), 0.3 (Cr), 0.1(Cd), 0.2(Pb), 0.2(As), 0.1(Ni). However, Co and Zn were not detected. Comparison of the metal contents in the water sample with WHO limits showed that the mean levels of all the metals were below the maximum permissible levels for drinking water. |
