ABSTRACT Iron deficiency anaemia (IDA) has been a significant public health problem in the developing world. Fortification has been identified as one o f the most cost-effective and sustainable approaches for controlling IDA. Addition of various bionutritional substances creates several technical challenges for the Food Technologists and therefore it is necessary to maintain the overall quality o f the product in terms o f the bioavailability o f the fortifying agent. The main objective...
ABSTRACT Cowpeas are a relatively inexpensive source of proteins and vitamin B. Unfortunately, the problem of insect infestation is one of the main constraints to the efficient and widespread utilisation of cowpeas. The hydrothermal treatment which involves the exposure of cowpeas to steam followed by drying has been used effectively in protecting cowpeas against the insect infestations. This study set out to assess the functional, chemical and textural changes associated with the hydro...
ABSTRACT Utilization of cassava, which contributes 22% of the gross agricultural product in Ghana, is limited by its high perisability, low protein content and toxicity due to the presence of the cyanogenic glucoside, linamarin and lotaustralin. Akyeke, a fermented and granulated, steamed-cooked cassava meal consumed extensively along the southwestern parts of Ghana is one of several products prepared from cassava in order to reduce postharvest loss of the crop. Fermenting grated cassava...
ABSTRACT The efect of therma-extrusion processing of white yam (Dioscorea rotundata) and bambara nut (Vigna subterranean) on some selected exwe parameters of residence time, throughput and moisture content were investigated in this study. Both yam and bambara nut were processed into meals of 750 pm and 500 pm respectively. Extrusion was carried out following a three variable response surJace methodology using a Box Behnken design. Blend of yam meal and Bambara nut meal at ratio 80:20 respect...
ABSTRACT Cassava (Manihot esculenta Crantz) peel is one of the solid wastes produced as a consequence of cassava processing. It is low in protein but contains a large amount of carbohydrate, causing an environmental problem with disposal. In order to add-value to this major cassava processing waste and also reduce its resultant environmental pollution, this study investigated the effect of submerged fermentation using Trichoderma viride ATCC 36316 on the protein content and amino acid profile...
ABSTRACT The seeds of cotton (Gosspyium hirsutum) fall among the lesser known oil seeds. Cottonseeds are not normally consumed in their natural state due to their gossypol content, an antinutrient. The effect of processing on the sensory characteristics and chemical composition of cottonseed and its extract was studied by subjecting the cottonseed extract to heat treatment (boiling) and the cottonseed to fermentation. The cottonseed extract was boiled using the open pot and the pressure pot f...
Abstract Solid state fermentation of cassava peel with emphasis on protein enrichment using Trichoderma viride was evaluated. The effect of five variables: moisture content, pH, particle size (p), nitrogen source and incubation temperature; on the true protein and total sugars of cassava peel was investigated. The optimum fermentation period was established to be 8 days. Total sugars were 5-fold higher at pH 6 relative to pH 4 and 7-fold higher when cassava peels were fermented at 30oC relati...
ABSTRACT Biscuits were produced from blends of acha and cowpea flours. The blends were lWO& 90% 80% 70% and 60% acha with cowpea flour to make 100% in each. Proximate composition, trypsin inhibition activity, functional properties including water absorption index, fat absorption index, gelation capacity, bulk density and emulsifying capacity of the blends were determined. Biscuits were produced from the blends. Trypsin inhibition activity, physical properties of the biscuit including break st...
Abstract The postharvest losses in fruits and vegetables in developing countries vary between 15-90%. Many organizations are actively promoting the processing of fruits and vegetables to find a solution to the difficulties encountered in storing large quantities of fresh produce without incurring heavy losses. This study evaluated the chemical, microbiological and sensory properties of leather blends produced from 'Ogbomoso' mango and carrot. Purees of mango (Mangifera indica 'Ogbomoso') and...
ABSTRACT Bambara nut was subjected to different treatments prior to mechanical dry dehulling and milling into flours. Physicochemical properties of the flours and sensory attributes of moin-moin prepared from the flours were compared with that of moin-moin from fresh pastes from cowpea and Bambara. The functional properties investigated included foam-ability, foam-stability, gelation capacity, dispersibility and dehull-ability while proximate chemical composition of the flours was also invest...
Abstract This study was conducted to investigate effects of extrusion conditions on physicchemical properties of blend of yam and bambara nut flours. Blend of white yam grit (750 pm) and Bambara nut flour (500 pm) in ratio 4: 1 respectively was extrusion cooked at varying screw speeds 50-70rpm, feed moisture 12.5-17.5% (dry basis) and barrel temperatures 130-150 OC. Extrusion variables employed included barrel temperature (BT), screw speed (SS) and feed moisture content (FM), while physico-c...
ABSTRACT Cocoa beans are the main ingredient for making chocolate and in Ghana, it is a major contributor to the economy as it generates an annual foreign exchange of about US $2 billion. The ability to produce high quality cocoa beans free from moulds and mycotoxin contamination has therefore become critical due to the impact mycotoxins have on health of consumers and global trade. This study investigated changes in fungal growth, mycotoxin concentrations, physico-chemical properties and coc...
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...
ABSTRACT The prevalence of under nutrition in many communities requires the need for the availability of nutrient dense affordable food supplements such as Ready-to-use supplementary foods. An energy dense, drinkable ready to use supplementary food produced by enzyme hydrolysis of cooked mixture of peanuts, cowpeas and rice with added vitamin mineral mix was both acceptable to consumers and showed promise of efficacy in improving the nutritional status of women of child bearing age through ...
ABSTRACT Open sun drying (OSD) has been a fish processing method for ages. In Ghana women form a large number of processors. Post-harvest losses still prevail in the trade due to poor fish handling, processing and storage which results in poor quality of dried fish. Solar drying has been introduced to improve on quality of OSD dried fish. A survey of open sun drying practices (OSD) at Kasoa (Central Region) and Tema (Greater Accra Region) showed poor hygiene practices and low value of product...
