The food potentials of tigernut tubers (Cyperus esculentus) locally know as “aki awusa” in Igbo, ”aya” in Hausa and “ofio” in Yoruba were evaluated. The proximate composition of 100g of raw and processed tigernuts showed that moisture content of tigernuts ranged from 4.19 – 51.93 %, crude protein 2.61 – 10.12 %, ash 0.70 – 1.77 %, crude fibre 7.48 – 13.97 %, crude fat 10.79 – 32.06 %, and carbohydrate 22.73 – 56.85 %. Energy values ranged from 232.31- 487.15 Kcal. Tigernuts contain significant amounts of Mg (95.32 -140.96 mg), K (106.44 – 427.92 mg), P (121.78 – 195.95 mg), Fe (1.60 – 4.03 mg), Cu (0.08 – 0.99 mg), Zn (0.32 - 2.46mg), vitamin C (30.90 – 84.66 mg), vitamin E (2.22 – 5.26 mg), moderate Ca (24.42 – 62.29 mg) and low Na (15.77 – 18.27 mg) content. Processing of tigernuts generally increased carbohydrate but decreased magnesium and sodium values.
This study determined the chemical composition and organoleptic attributes of three selected vegetables consumed in Njikoka local government area, Anambra state, Nigeria. The vegetables used for the study were Ipomea batatas, Portulaca olercea and Corchorus tridens purchased from local market in Enugwu-Ukwu, Njikoka local government area, Anambra State, Nigeria. The vegetables were processed (sun and shade dried). The fresh samples served as the controls. Nine yam dishes based on fresh, sun and shade dried of the vegetables were prepared. The vegetable samples and the dishes were analysed for nutrient and antinutrient contents using modern assay techniques. The results demonstrated that shade and sun drying increased various nutrients. The nutrient values for the dishes were lower than those of the vegetable samples. The sensory evaluations of the dishes were generally accepted by the judges as judged by the results. The nutrient content of these lesser-known vegetables and their dishes are promising. These vegetables and their dishes could upgrade the micronutrient densities of some of our traditional d es based only on popular vegetables that are scarce during dry season.
This study was designed to assess the knowledge, attitude and adoption of appropriate infant feeding practices of mothers and the anthropometric indices of their children. Three hundred and seventy three mothers who attended infant welfare clinics at the three health settings (General hospital Ekwulobia, Primary health care Ekwulobia, and Primary health care Akpo) all in Aguata L.G.A were involved in the study. The study evaluated the nutritional status of the infants in relation to their anthropometric indices. Also infant feeding practices of mothers in the locality was assessed. A validated semi-structured questionnaire by experts at the Department of Home Science, Nutrition and Dietetics, University of Nigeria, Nsukka was used to elicit information on socio-economic characteristics of the mothers and their children. Results showed that age of the mothers involved in the study ranged from less than 20 years to 41 years and above.
This epidemiological study was to elicit information on the consumption pattern of antioxidant rich foods among middle-aged adults in Enugu North local government area, Enugu State, Nigeria. Four hundred adult men and women aged 40-60 years were used for the study. Multiple- staged stratified random sampling technique was used for selection of the subjects used for the study. The respondents were randomly selected from 10 streets in the 5 urban zones making up the Enugu North local government area. Structured questionnaire with personal interview was the instrument used for data collection. Information were collected on the demographic characteristics, chronic diseases that affected the respondents, general knowledge of food nutrients, concepts of antioxidant, free radicals, sources and their health implications and on consumption pattern of antioxidant rich foods. Also, data on the length of consumption pattern of antioxidant rich foods and those factors that could hinder adequate consumption of antioxidant rich foods were elicited. The statistical package for socials sciences SPSS version 12 was used for the data analysis. Percentages, frequency, mean and standard deviation were employed for the data analysis. Analysis of data revealed that 74% of the respondents were females and 26% were males, 78.8% were married, 85% had higher education and 80% were civil servants.
This study developed and evaluated infant – feed composite complementary food made from locally available foods which was fed to infants 6-12 months of age. Dried Moringa oleifera leaf was the fortificant. Yellow maize grains were fermented for 48h and oven –dried. Soybean seeds were boiled for 1h, dehulled and oven-dried. Moringa oleifera leaves were shade-dried. All the food materials were milled into fine flours. The proximate, energy, mineral and β-carotene contents of the flours were determined using standard methods. The flours were used to develop 2 blends in ratios of 60:40 (control) and 60:30:10 (test) maize + soybean and maize + soybean + Moringa oleifera leaves respectively. The analysis of the blends were done using standard techniques at 5% confidence level. The blends provided 10% protein. The blends were used to prepare gruels whose sensory evaluation was conducted using 30 mothers.
The study examined the chemical composition of fresh, sundried tender leaves and husks of cowpea ‘Adengee’ (Vigna unguiculata) and organoleptic attributes of their traditional soups. Information on processing, preparation and utilization of soup meals based on cowpea leaves and husks were obtained during the focus group discussion. The tender leaves and husks were parboiled and sundried. Proximate, micronutrients, phytochemicals and antinutrient levels were determined using standard procedures. The soups based on fresh and sundried leaves and husks were analysed prior to sensory evaluation. The data collected were statistically analysed using means, standard deviation and standard error. All values were based on residual moisture. Protein for dried leaves was higher (p
The thrust of this work was to identify some popular and lesser-known cultivated and forest green leafy vegetables consumed in Igbo-ukwu, Aguata LGA, Anambra State, Nigeria. Those identified include ugbogulu, eliemionu, ariraa, okpa okuku, ugu oyibo and abuba ji nwannu, used in this study. These vegetables were purchased in bulk from Igboukwu daily market, cleaned and divided into 3 portions. Fresh portions served as the controls. The sun and the shade dried samples were the processed portions.
This study was aimed at assessing the iron, zinc and anthropometric indices of pre-school children aged 2 – 5 years in Ozubulu. A total of two hundred and forty (240) preschool children were randomly selected. Questionnaire, anthropometric measurements, biochemical analysis and 3–day weighed food intake were used for data collection. Two hundred and forty (240) questionnaires were distributed to mothers and caregivers of the selected children. Out of the 240 samples, sub samples of thirty children were randomly selected for biochemical assessment of iron and zinc status and for 3-day weighed food intake analysis. Iron status was assessed in terms of transferrinemia (serum iron, total iron binding capacity and percentage transferrin saturation) while zinc status was assessed using serum zinc.
This study investigated the nutritional status of children living in Ika North East Local Government Area of Delta State. Data on nutritional status was obtained from 300 children within the age range of 6-24 months randomly selected. Validated and pre-tested semi-structured questionnaire was used to elicit information on the socio-economic characteristics of the nursing mothers. Breast and complementary feeding practices and the processing methods used in producing these complementary foods were also investigated. A 24-hour dietary recall and three-day weighed food intake were used to assess the food intake pattern of 30(10%) children. The results from the questionnaire showed that majority (73%) of the mothers used mostly maize, rice, yams and cassava in feeding their children. About 37% combined either corn-pap/ custard with powdered milk, soybean flour (7%), ground crayfish (7%), sugar (6%) and salt (2%).
The effects o f women's work on child nutrition was investigated in Awka and Mgbakwu communities of Anambra state, in Nigeria.
