Development of Extruded Complementary Foods from Blends of Acha . land Cowpea Flours

ABSTRACT Despite the fact that a variety of improved traditional African complementary foods have been developed from cereal-legume blends (1,2), the traditional products that are a leading cause of protein-energy malnutrition, still remain the primary weaning foods, especially in rural communities, largely because of the high cost of improved complementary foods, The ingredients for low-cost complementary foods must be derived from dietary staples available and affordable in the region of in...

Current applications of probiotic foods in Africa

Currently, there is a growing interest in the consumption of probiotic foods due to their reported health benefits. In developed countries, probiotics have been extensively studied and this has led to the production of a variety of probiotic foods especially with dairy milk. However, the use of beverages from plant materials as a potential carrier of probiotic microorganisms is receiving increasing attention. Various indigenous fermented foods containing probiotic bacteria have been part of l...

Physico-thermal and pasting properties of soy-melon-enriched “gari” semolina from cassava

Abstract: The physical, thermal and pasting properties of “gari”, a fermented and toasted cassava granule, enriched with 10% full fat soy-melon protein supplements, at different processing stages, were studied. The stages at which the gari meal was enriched were: after fermentation but before toasting (PRT, soak-mix method) and after toasting (AFT, dry-mix method). Based on the result of the analysis of the physical properties, the swelling index of the samples decreased from 3.79 for the...

EFFECT OF CO-FERMENTATION ON NUTRITIVE QUALITY AND PASTING PROPERTIES OF MAIZE/COWPEA/SWEET POTATO AS COMPLEMENTARY FOOD

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...

Ethanol Yield of Three Varieties of Cassava (Odongbo, Ofege, and TMS 30572) Using α-Amylase from Germinated Paddy Rice and Yeast from Palm Wine

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...

Development of extraction protocol for phenolic compounds in musk tree seed (Buchholzia coriacea)

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...

Proximate and sensory properties of fruit juice produced from varieties of watermelon (Citrullus lanatus).

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...

Physical Properties of Cookies Produced from Cassava – Groundnut-Corn Starch Blend- A Response Surface Analysis

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...

A Philosophical Appraisal of the Politics and Economics of Food in Africa

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...

Effect of Leaf-Type on the Nutritive and Organoleptic Properties of Ogiri-Egusi (Fermented Citrullus vulgaris) Seeds

ABSTRACT---- The effect of wrapping type on the nutritive and organoleptic properties of Ogiri-egusi (fermented Citrullus vulgaris) seeds was studied. The leaves used were miracle fruit leaves (Thaumatococcus danellii), cocoyam leaves (Colocasia spp), and banana leaves (Musa sapientum). The melon seeds were hulled, sorted and washed, boiled for 4h, ground and then wrapped in small portions in different leaf-types and fermented for five days. Proximate analysis and sensory evaluation were...

Phenolics Comparison between Twinning and Celestial Peppermint Teas using HPLC-DAD

Abstract Twinings and Celestial pure peppermint herbal tea is made from 100% select peppermint leaves and is naturally caffeine and gluten-free and parts of their differences lie in the packaging. The HPLC profile of Twinning peppermint and celestial peppermint teas showed that both the teas samples contain caffeic acid, ellagic acid, pcoumaric acid, rosmarinic acid and rutin while celestial peppermint tea had an extra phenolic compound called quercetin. Quercetin was known for its anti-i...

A COMPARATIVE STUDY OF THE FUNCTIONAL PROPERTIES OF FLOURS FROM THREE VARIETIES OF SWEET POTATO (Ipomoeas batatas) ROOTS

ABSTRACT This study was undertaken to assess the functional properties of flours from three varieties of sweet potato (Ipomoeas batatas). The varieties used in this study include orange flesh sweet potato – ‘Umuspo – 3 (Mother’s Delight)’, cream flesh sweet potato – ‘Ex-igbarium’ and red skin-white flesh sweet potato varieties. The functional properties analysed include Swelling power, Water absorption capacity, Oil absorption capacity, Bulk density and least gelation capacity...

Proximate Composition and Antihtperglycaemic Effects of Selected Plant Products

Abstract The proximate, dietary fibre, mineral and antinutrient compositions of Gongronema latifolium (leaves), Gymnema sylvestre (leaves), Corchorus olitorius (leaves) and Bulchozia coriceae (seeds) were evaluated. Diabetes was induced in selected albino rats while the control groups were normal. Both groups were fed diets containing different levels of each plant product (0, 2.5, 5.0, 10.0 and 20.0% respectively) for twenty-eight days. Effects of plant products on blood glucose, sodium, pot...

TECHNICAL AND ECONOMIC PLANS FOR THE DESIGN OF A FACTORY TO PRODUCE 500,000 METRIC TONNES OF CHOCOLATE LIQUOR PER ANNUM

ABSTRACT Cocoa is the common name for some species in the genus Theobroma (family Theobromaceae).   Cocoa are a mixture of many substances remaining after cocoa butter is extracted from cacao beans. When sold as an end product, itmay also be called cocoa powder, cocoa, and cacao. In contrast, the fatty component of chocolate is cocoa butter. Cocoa butter is 50% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa liquor or cocoa mass is a paste...
