Abstract Traditional complementary foods based on cereals have inadequate nutrients required by infants. This study developed a co- fermentation process of maize (50%), cowpea, (30%) and sweet potato (20%w/w) to produce a complementary food for infants. The control was fermented whole grain maize. Gruel of fermented cereal is called ‘ogi’ in Yoruba native language of south-west Nigeria. Analyses of proximate composition, minerals, amino acids and ß-carotene contents were done using stand...
AbstractA process of conversion of flour from three varieties of cassava, namely Odongbo, ofege and TMS30752 to ethanol using α-amylase locally sourced from germinated unhusked paddy rice and yeast isolated from palm wine was developed. It involves the germination of paddy rice for a period of 15days to produce α- amylase for starch hydrolysis and isolation of yeast from palm wine for fermentation. The results showed that optimum amylase yield of “ofada” rice paddy was at 6th day germin...
The impact of extraction methodology and polarity of extraction solvents on the assay of phenolic compounds was investigated using musk tree seed (Buchholzia coriacea) as a model substrate. The efficiency of four solvents (methanol, ethanol, acetone and ethyl acetate) at 20, 40, 60, 80 and 100% aqueous solution and five extraction methods (shaking, vortex mixing, stirring, sonication, sonication/vortexing and accelerated solvent extractor) in extracting the phenolics of B. coriacea were evalu...
Abstract Watermelon (Citrullus lanatus) juice was produced from different varieties of watermelon (Dansuke, orangeglo and cream of Saskatchewan). Single strength orange juice was used as control. Proximate composition of sample products was analyzed. Results showed that single strength orange juice had more moisture and protein (93.41% and 0.74% respectively) than the water melon juices. The watermelon juice had more carbohydrates, fat and ash. Taste of single strength orange juice was c...
ABSTRACT Cookie bars were produced from mixtures of cassava and groundnut flours with cornstarch as binder. Box-Behnken response surface design for k=3 was used to study the effects of experimental variables for cassava flour (25- 75%), groundnut flour (25-75%) and corn starch (5-15%). Effects of the experimental variables on physical properties of the cookie bars were assessed. Experimental variables had significant effect on the thickness and spread factor of the cookie bars. Keywords: P...
ABSTRACT Cheese is a concentrated dairy product produced by acid or rennet curdling of milk, stirring and heating the curd, draining off the whey, collecting and pressing the curd. In this study, Cheese was made from cow milk supplemented with tigernut milk and coconut milk in the percentage ratio of 25:25:50; 25:50:25; 50:25:25; 75:25:0; 75:0:25% cow- tigernut milk-coconut milk (v/v). The unsupplemented cow milk cheese was used as control. The quality, shelf life and sensory attributes of th...
ABSTRACT Native Starch was extracted from Aerial yam (Dioscorea bulbifera). The starch extracted was dried using oven (at 300C for 24 hours) and microwaved for (30, 45, 60 seconds). Starch obtained using different drying methods and conditions were analysed for their physicochemical, functional properties and pasting characteristics. Results obtained showed that amylose, amylopectin, colour, pH, bulk density, swelling power, least gelation capacity, oil absorption capacity, water absorption c...
ABSTRACT Oils extracted from the fruits of two Africa spices- Piper guineense and Xylopia aethiopica were evaluated for their antimicrobial activities using Escherichia coli, Salmonella sp, Aspergillus sp, Bacillus cereus, Penicillum commune and Rhizopus stolonifer as test isolates. Well-in-agar, disc diffusion and dilution susceptibility testing methods were used to assay for their antimicrobial properties. For the bacterial isolates the antimicrobial activity of the oils increased with ...
Background of the study There is increased advocacy on the consumption of functional foods by World human nutrition due to different health problems related with food consumption such as diabetes and coronary heart diseases (WHO/FAO, 2003). Food professional/industries might face challenges of producing food products containing functional ingredients in order to meet the nutritional requirements of individuals with health challenges. This is because of the effect of added sugar and lipids i...
ABSTRACT Ready-to-eat vegetables and fruits have intrinsic properties predisposing them to microbial contamination especially in the absenceof proper quality control procedures. Recently, the increased in consumables bio-burden manifested as the accumulation of potentialpathogenic microbes therein which triggered the food related ailments associated with morbidity and mortality cases. Evaluating themicrobial quality of such foods is therefore important. This study was aimed at evaluating the ...
ABSTRACT Lecithin is used for applications in human food, animal feed, pharmaceuticals, paints, and other industrial applications, but consistent importation of lecithin has a negative effect on foreign exchange leading to devaluation of the naira. The need to explore locally available products such as cassava starch as a possible substitute to the use of lecithin is paramount, hence, the reason for this work. This research was carried out to evaluate the emulsification properties of�...

The research design involved the random sampling approach which was adopted in the selection of the six (6) zobo samples from the 5 different markets within Awka metropolis while the last zobo sample...
ABSTRACT In ensuring the prevention of losses when raw agricultural product is in the peak of its season and to assure safety, effective method of packaging and processing is highly indispensable. This study researched into the property of stored tomato concentrate packed in glass bottle, plastic bottle and polyethylene stored in the presence of light and in the absence of sunlight. Tomato concentrate...
The continent of Africa has recorded impressive economic growth for over two decades. Factors identified as contributing to this growth include commercial oil deposits, inflation control, government liberalization and privatization policies, foreign direct investment, private sector investment in industries such as construction and service sectors, and a strong agricultural production. The continent is likely to continue enjoying strong economic growth if these resources are well managed. Afr...
