Current Position of Sanitation in Nigerian Food Industries
R.O. Adeleke
Pakistan Journal of Nutrition , 2010,
Abstract: Evaluation of conformity of major commodity food industries to sanitation standards was carried out. Major fourteen food industries were investigated include dairy industry, bakery, beverage factory, fish processing industry, brewery, cereal processing and fruit canning industry. The survey shows that most Nigerian food industries were designed, constructed and operated without sufficient consideration for many important sanitary factors and without adequate facilities of the right kind or the type of conditions which would promote good personal hygiene and impeccable plant sanitation. Few of the industries performed satisfactorily in some of the area investigated while four companies attained the minimum standard specified in this survey on all overall basis. Much more attention needs to be paid to rodent and pest control, water treatment, waste disposal and utilization.

R.O. Adeleke,J.O. Odedeji
Pakistan Journal of Nutrition , 2010,
Abstract: In this study the functional properties of wheat and sweet potato tuber (Ipomea batatas) flour blends were investigated. The sweet potato tubers were brought from local farm in Offa Kwara State. The tubers were thoroughly sorted, washed, peeled, sliced, blanched, soaked, drained, sundries and milled into flour. Wheat flour used was purchased at Orisumbare market in Osogbo Osun State. The wheat and sweet potato flour were blended using the following ratios (WF:SPF:100:0, 90:10, 85:15, 80:20, 75:25, 0:100). These samples were thereafter subjected to functional properties analysis. The results revealed that as more and more sweet potato flour was added to wheat flour, there was significant effect on the functional properties.
Acceptability Studies on Bread Fortified with Tilapia Fish Flour
R.O. Adeleke,J.O. Odedeji
Pakistan Journal of Nutrition , 2010,
Abstract: This study was conducted to assess the acceptability of bread samples produced by fortification of wheat flour with Tilapia Fish Protein Flour (TFPF) in varying proportions (5, 10, 15 and 20% by weight of wheat flour). Bread produced from 100% wheat flour served as the control. The fortified bread and the control samples were subjected to proximate and organoleptic analysis. The result of proximate analysis revealed that the incorporation of TFPF into wheat flour resulted in improvement in the nutritional value of bread sample. The protein content increases as more and more TFPF was added. The protein content for the control sample was 9.08% while the values for fortified bread samples ranged between 18.01 and 10.59% with sample coded 411 (80% wheat flour: 20% TFPF) having the highest value. The result of organoleptic analysis revealed that there was no significant difference among the samples in term of taste, aroma, crust and crumb colour and overall acceptability. Acceptable fortified bread could therefore be produced from wheat and TFPF.

O.A. Abiodun,R.O. Adeleke
Pakistan Journal of Nutrition , 2010,
Abstract: This study evaluates four Cucurbit species in Iree, Osun state, Nigeria. The species used were Cucumeropsis manni (Naudin), Cucumis sativus, Leganaria siceraria and Cucumeropsis edulis (Hook). Proximate and mineral analyses were carried out on the shelled Cucurbit species. Protein, fat, ash, crude fibre, moisture and carbohydrate content ranged from 33.80-39.96%, 40.26-45.21%, 3.35-4.89%, 1.66-2.16%, 4.78-5.21 and 7.08-14.15% respectively. There were significant difference (p<0.05) in the values obtained in protein, fat, ash moisture content and carbohydrate. But there was no significant difference (p<0.05) in crude fibre values for Cucumeropsis edulis and Cucumis sativus. Cucumis sativus had higher calcium content (2.03%) while Cucumeropsis manni had higher values in Mg (8.87%), Na (162.76 ppm), Mn (107.72 ppm) and Fe (39.71 ppm) contents. Leganaria siceraria also had higher values in K (5.43%), Cu (5.09 ppm) and Zn (19.75 ppm). Acid value ranged from 3.13-4.22 mgKOH/g, free fatty acid ranged from 3.4-3.9%. Saponification and peroxide values of 188-193 mg KOH/g and 9.7-11.6 Meq/kg were obtained for the melon seeds oils. Also, iodine values for the melon seeds ranged from 95.5-98.2 Wijs. All the seeds serve as good sources of protein, fat and minerals.

Pakistan Journal of Nutrition , 2010,
Abstract: This study was conducted to investigate the pasting characteristics of wheat and sweet potato tuber (Ipomea batatas) flour blends. The sweet potato tubers were bought from a local farm in Offa, Kwara State. The tubers were thoroughly sorted, washed, peeled, sliced, balanced, drained, sundried and milled into flour. Commercial wheat flour was used and purchased from Igbona market in Osogbo, Osun State of Nigeria. The wheat and sweet potato flour were blended using the following ratios (WF : SPF : 100 : 0, 90 : 10, 85 : 15, 80 : 20, 75 : 25, 0 : 100). These samples were thereafter subjected to pasting characteristics analysis. The results revealed that as more and more sweet potato flour was added to wheat flour there was improvement in the pasting properties.
Physico-chemical Properties of Commercial Local Beverages in Osun State, Nigeria
R.O. Adeleke,O.A. Abiodun
Pakistan Journal of Nutrition , 2010,
Abstract: This research work evaluates the physico-chemical properties of local beverages form, Osun State. Nigeria. The drinks were analyzed for PH, titratable acidity, specific gravity, total soluble solids, ethanol content, total solids, total sugar, reducing sugars, non reducing sugar and ascorbic acid. From the analysis, the PH value ranged from 4.2-6.3, the titratable acidity ranged from 0.8-11.7. The highest specific gravity was in fura da nunu (1.3180) and the lowest in ogogoro (0.9897). Total soluble solid ranged from 0.3-10.7%. Ogogoro (distilled palmwine) had the highest percentage of alcohol content of 37.6%, burukutu (sorghum beer) had 4.6% and palm wine had 3.1% while nunu (fermented skim milk), omi wara (cheese whey), kunnu zaki (millet food drink), Adoyo (maize drink) and fura da nunu (fermented skim milk with millet dough) had lower values. Fura da nunu had highest total solid (21.8%) and total sugars (7.5%). These values were significant different (p<0.05) from other samples. Adoyo had highest value of 32.0 mg/100 g ascorbic acid while ogogoro had the lowest value. The PH of ogogoro was nearer to neutrality compared with the other local drinks analyzed. Titratable acidity and ascorbic acid of zobo and pito were not feasible due to the products colour. The high alcoholic content of ogogoro, burukutu and palmwine signifies that the product can cause health problem such as obesity and can damage the organs in the body. Adoyo, fura da nunu, nunu and kunnu zaki are good source of ascorbic acid but diabetic patient may take them without sugar.
Upper esophageal sphincter pressure in patients with Chagas' disease and primary achalasia
Dantas, R.O.;
Brazilian Journal of Medical and Biological Research , 2000, DOI: 10.1590/S0100-879X2000000500009
Abstract: the most important component of the upper esophageal sphincter (ues) is the cricopharyngeal muscle. during the measurement of sphincter pressure the catheter passed through the sphincter affects the pressure value. in chagas' disease and primary achalasia there is an esophageal myenteric plexus denervation which may affect ues pressure. we measured the ues pressure of 115 patients with chagas' disease, 28 patients with primary achalasia and 40 healthy volunteers. we used a round manometric catheter with continuous perfusion and the rapid pull-through method, performed in triplicate during apnea. pressures were measured in four directions, and the direction with the highest pressure (anterior/posterior) and the average of the four directions were measured. the highest ues pressure in chagas' disease patients without abnormalities upon radiologic esophageal examination (n = 63) was higher than in normal volunteers (142.8 ± 47.4 mmhg vs 113.0 ± 46.0 mmhg, mean ± sd, p<0.05). there was no difference in ues pressure between patients with primary achalasia and patients with chagas' disease and similar esophageal involvement and normal volunteers (p>0.05). there was no difference between patients with or without esophageal dilation. in the group of subjects less than 50 years of age the ues pressure of primary achalasia (n = 21) was lower than that of chagas' disease patients with normal radiologic esophageal examination (n = 41), measured at the site with the highest pressure (109.3 ± 31.5 mmhg vs 149.6 ± 45.3 mmhg, p<0.01) and as the average of the four directions (64.2 ± 17.1 mmhg vs 83.5 ± 28.6 mmhg, p<0.05). we conclude that there is no difference in ues pressure between patients with chagas' disease, primary achalasia and normal volunteers, except for patients with minor involvement by chagas' disease, for whom the ues pressure at the site with the highest pressure was higher than the pressure of normal volunteers and patients with primary achalasia.
Theories and Concepts in Migration and Settlement Studies: The Case of the Coastal Yoruba
R.O. Ajetunmobi
The Social Sciences , 2013, DOI: 10.3923/sscience.2012.289.296
Abstract: The study of the Coastal Yorubaland as a regional group is of recent phenomenon. The traditional history of the various subgroups such as the Awori, Ilaje and Ijebu waterside is replete in theories and concepts of migration. The study of these theories and concepts in the settlement studies of the groups will enhance the knowledge of the Yoruba of the coastal environment. This presentation focuses on the analysis of the theories and concepts of migration of the Yoruba of the Coastal Nigeria which has not been given adequate attention. The study relies on diligent collection and interpretation of oral, ethnographic, archival and secondary source materials. The study observed that the pull and push factor in the settlement of the various coastal Yoruba found expression in economic, political, social, religious and geographical factors. The pattern of migration was from less favourable environment to more favourable one leading to fission and fusion of groups. The religious factor, especially that of the Ifa oracle played a dominant role in the settlement of many groups while the Ife connection remains a binding force.

Comparative Survival and Growth Rate of Clarias gariepinus and Heteroclarias Hathclings Fed Live and Frozen Daphnia
R.O. Ojutiku
Pakistan Journal of Nutrition , 2008,
Abstract: Feeding trial was conducted to assess survival and growth rate of Clarias gariepinus and Heteroclarias (hybrid of Clarias gariepinus and Heterobranchus longifilis) larvae (3-day old) fed on live and frozen Daphnids. Live and Frozen daphnia were used as starter diet at 50 Daphnids per larvae per feeding time for each of the species for fourteen days to assess their performance. The response to the feed and the species were compared. Heteroclarias and Clarias gariepinus fed live Daphnids performed better in terms of growth rate than those fed Frozen daphnids, though, no significant difference (p<0.05) statistically. Clarias gariepinus and Heteroclarias fed Frozen had greater survival than those fed live Daphnids. Heteroclarias fed live and Frozen Daphnids performed better in growth and survival than Clarias gariepinus. Therefore, Live Daphnids is recommended for larvae though Frozen Daphnids can be used as supplement and Heteroclarias is recommended for aqua culturists for better growth and survival.
