(2019) Apata, O. C.; Oyebade, O. J.; Ajayi, O. O.; Ajayi, O. O.; Adebayo, I. N.; Meludu, N. T.; Ayodele, I. A.
Backgronnd: Aadun is an indigenous maize-bascd snack high in energy, phosphorus and magnesium but low in protein. it is often sold with minimal packaging under conditions which may lead to its rapid deterioration. Protein fortification and improved packaging could enhance its balance of nutrients and increase acceptability. Objective: The study evaluated the chemical composition and organoleptic qualities of fortified, aadun. Methodology: Four different samples of aadun were prepared. T0 served as the control (unfortified aadun) while the three others (T i, T2 and T3 were fortified with groundnut, cray fish and soybeans, respectively. The four samples were subjected to proximate and mineral analysis. Different packaging materials such as foil paper, polyethylene and plastic plate covered with kiln film were used to present the samples to 50 panellists for organoleptic assessment. Results were subjected to descriptive statistics and ANOV A using SPSS version 20 Results- fortified samples were found to be significantly different in their chemical composition and sensory attributes from the control sample. The fortified aadun samples had higher protein, crude fibre, ether extract, iron magnesium, iodine, sodium, potassium and phosphorus due the control. The T0, was rated highest for the colour and the T1 for taste, texture, aroma and overall acceptability. The most preferred packaging material for the samples was plastic plate covered with kiln film while polyethylene was least preffered. Conclusion: Fortifying aadun with different ingredients especially groundnut and improving the materials used in packaging will improve its consumer acceptability.
Endocrine disruptors-arsenic, cadmium and lead in pre and postmenopausal black women with breast cancer
(University College Hospital, Ibadan, 2017) Ajayi, O. O.; Charles-Davies, M. A.; Anetor, J. I.; Ademola, A. F.
Background: The involvement of toxic metals in adiposity has been suggested to be contributory to the high incidence of breast cancer, particularly in sub-Saharan Africa. This study is aimed at evaluating serum arsenic, cadmium and lead in relation to adiposity and blood pressure in Nigerian women with breast cancer. Methodology: The study comprised 85 women newly diagnosed with breast cancer pre-therapy (cases) matched with 84 apparently healthy women without breast cancer (controls) according to age and menstrual phase. Arsenic (As), cadmium (Cd) and Lead (Pb) levels were determined by atomic absorption spectrophotometry. Blood pressure and anthropometry were determined by standard methods. Data analysed by Student’s t-test and Pearson correlation coefficient were considered statistically significant at p<0.05. Results: Cd and Pb levels were significantly higher in cases, compared with controls (p<0.05). Waist circumference (WC), hip circumference (HC), weight, height, waist hip ratio (WHR), waist height ratio (WHtR) were significantly higher in cases compared with controls (p<0.05). Cadmium positively correlated with diastolic blood pressure while FT4 inversely correlated with arsenic in the cases (p<0.05). Conclusion: Observations in this study suggest the involvement of these toxic metals in adiposity which could be involved in breast carcinogenesis.
Enterprise characteristics of selected hotels for indigenous snacks acceptability in South-West, Nigeria
(Home Economics Research Association of Nigeria, 2018-12) Apata, O. C.; Abimbola, A. F.; Ajayi, O. O.; Meludu, N. T.; Ayodele, I. A.
The study assessed the enterprise characteristics of various tourists' centers across the selected states in Southwest Nigeria. It was conducted in selected hotels and tourists centers in southwest Nigeria. Twenty caterers were 1 randomly selected in each hotel and tourist centers. Data were collected using questionnaire and analyzed using frequencies and percentages. The findings of the study show that indigenous snacks were offered in lower proportion to continental snacks in hotels across the states in south-west Nigeria, these snacks are prepared and packaged hygienically and also theses hotels have adequate recreational facilities. The study recommended that workshops and seminars should be organized on promotion of indigenous snacks into hotels and tourists centers.
Progesterone, selected heavy metals and micronutrients in pregnant Nigerian women with a history of recurrent spontaneous abortion
(Makerere University, Medical School, 2012-06) Ajayi, O. O.; Charles-Davies, M. A.; Arinola, O. G.
Background: Environmental and endocrine factors have been implicated in the aetiology of recurrent abortion, with poorly understood roles. Luteal phase insufficiency marked with insufficient progesterone secretion has been reported. Objective: To define the involvement of progesterone, trace metals, and Vitamin E in pregnant women with history of recurrent spontaneous abortion. Methods: Convenience sampling method was used to recruit 69 pregnant women aged 21-41 years with gestational age of 0-20 weeks in this case-control study. Thirty five (cases) and thirty four (controls) had previous and no history of recurrent spontaneous abortion respectively. Demographic characteristics and 10mls of blood samples were obtained from each subject. Serum obtained was used for the determination of progesterone, zinc, copper, selenium, iron, magnesium, manganese, chromium, lead, cadmium, and serum vitamin E by standard methods. Results: Results showed statistically significant decreases (p<0.05) in the serum zinc, copper, and vitamin E and a significant elevation (p<0.05) in the serum selenium, lead, and cadmium in cases compared with controls. Insignificant decrease (p=0.07) was observed in the serum progesterone when cases were compared with controls. Conclusion: Results suggest that elevated serum heavy metals (cadmium and lead) and reduction of essential micronutrients (zinc, copper and vitamin E) may contribute to recurrent spontaneous abortion.
Proximate composition and microbial characteristics of processed tiger nut milk (cyperus esculentus)
(Home Economics Professional Association of Nigeria (HEPAN), 2020-03) Apata, O. C.; Ajayi, O. O.; Adebayo, I. N.
This study investigated the proximate and microbial characteristics of processed tiger nut milk. Tiger nut was purchased, processed under standard conditions and subjected to laboratory analysis in triplicates. The result showed that the sample contain 90.7% moisture content. 0.6% crude protein. 2.7% crude fat. 0.1% crude fibre. 0.2% ash and 5.7%> carbohydrate. The microbial toad was found to the higher than the FAO/WHO standard. The pH was found to decrease from 5.5 at preparation to 3.2 after 18 hours. It was concluded that tiger nut milk is a nutritious beverage with high moisture content hut low crude fibre, crude protein, crude fat and ash content. The milk decrease in pH suggested increase in acidity which aids spoilage.
Service quality and customer loyalty in hotels within Ibadan metropolis, Oyo State
(2019) Apata, O. C.; Afolabi, T. D.; Ajayi, O. O.; Abimbola, A. F.; Adebayo, I. N.; Okhiria, A. O.
The study assessed the effect of service quality on customers’ loyalty in hotels within Ibadan metropolis. Random and convenience sampling was used to sample 192 respondents from thirteen hotels in four local government areas within Ibadan metropolis. Data were analyzed using descriptive and inferential statistics. The findings revealed that there was an overall statistically significant correlation between service quality and overall loyalty (r = 0.439, p<0.01), word of mouth (r = 0.427, p< 0.01) and repeat patronage (r= 0.443, p< 0.01), there was no significant relationship between service quality and price insensitivity (r = 0.439, p>0.01). Overall expectation towards tangibility was at the agree level (4.18) while perception was ranked at the strongly agree level (4.24 )and (4.22), overall expectation towards reliability is at the agree level (4.06) and responsiveness was at the agree level (4.17), perception of responsiveness dimension was at the strongly agree level (4.26), overall expectation towards assurance was at the agree level (4.12), perception of assurance dimension was ranked at the agree level (4.19) and empathy dimension was ranked at the strongly agree level (4.29), while overall expectation towards empathy was at the agree level (4.27). There was significant relationship between service quality and customer loyalty.
