Influence Of Fermentation And Cowpea Steaming On Some Quality Characteristics Of Maize-Cowpea Blends, Samuel Sefa-Dedeh, Yvonne Kluvitse, Emmanuel Ohene Afoakwa Jul 2001

Influence Of Fermentation And Cowpea Steaming On Some Quality Characteristics Of Maize-Cowpea Blends, Samuel Sefa-Dedeh, Yvonne Kluvitse, Emmanuel Ohene Afoakwa

Professor Emmanuel Ohene Afoakwa

Fermentation and cowpea steaming can be used to improve the protein quality and quantity of fermented maize dough. In the production of maize-cowpea blends, it is important that the quality characteristics are evaluated to determine their functionality in the products. A 5x4x2x2 factorial experiment with cowpea level, fermentation time, cowpea steaming time and fermentation method as the variable was performed. The cowpeas were dehulled, steamed, dried at 65EC for 24 hours and milled into flours. Maize was soaked in water (18 hours), drained and milled into flour. The maize-cowpea blends were made into a 50% moisture dough, fermented for the …

Chemical Composition And Quality Changes Occurring In Dioscorea Dumetorum Pax Tubers After Harvest, Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh Mar 2001

Chemical Composition And Quality Changes Occurring In Dioscorea Dumetorum Pax Tubers After Harvest, Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh

Professor Emmanuel Ohene Afoakwa

Studies were conducted on the chemical composition, as well as the biochemical and textural changes, occurring during storage of two cultivars of Dioscorea dumetorum yam tubers. The tubers were harvested and stored under tropical ambient (28_C) and cold room conditions (4_C) for 24, 48 and 72 h. The samples were evaluated for moisture, starch, sugars, fibres and textural properties. Chemical analysis showed no significant differences between the means obtained for moisture, ash, protein, fibre, fat, carbohydrate, calcium, phosphorus, iron, vitamin A and vitamin C contents of the cultivars (white and yellow) studied. During storage, moisture contents decreased by approximately 6–10% …

Ecological Sustainability For Pastoral Management, Hugh Pringle, Ken Tinley Jan 2001

Ecological Sustainability For Pastoral Management, Hugh Pringle, Ken Tinley

Journal of the Department of Agriculture, Western Australia, Series 4

Pastoralists and rangeland bureaucracies are now required to operate within the limits of ecological sustainability. However, while the concept of ecological sustainability has been enshrined in law and policy at State and Commonwealth levels in Australia, there has been little translation into pastoral management objectives. The introduction of the 'EMU (Ecosystem Management Unit) process', as an equal partnership between ecologists and pastoralists, promises to bring pastoralists into close dialogue with the landscapes they manage on their stations, and to acknowledge and manage for values other than pasture production. In doing so, pastoralists are likely to increase production, reduce costs, and …

Analysis Of A Mixed Cereal Of Legumes That Processes Similar Nutritional Characteristics To A Cereal Product Of Local Consumption And Its Economic Feasibility, Willy Ivan Anzaldo Garcia Jan 2001

Analysis Of A Mixed Cereal Of Legumes That Processes Similar Nutritional Characteristics To A Cereal Product Of Local Consumption And Its Economic Feasibility, Willy Ivan Anzaldo Garcia

Theses and Dissertations

In this analysis, we plan on developing vegetable mixes with high nutritional qualities and instant fuel consumption. These are to be used as a nutritional supplement in the feeding of children from 6 months of age. Initially, I selected the raw material, due to its high protein content and low cost (soy, tarhui, Cuban corn, rice, wheat, barley). They formed mixes with nutritional characteristics similar to the control for reference (15.5% of protein, 419 kcal of energy). From these formulas, different tests of completed production of mixtures, going so far as to obtain eight mixes with good nutritional and organoleptic …

Forest Dynamics In Flood Plain Forests In The Peruvian Amazon: Effects Of Disturbance And Implications For Management, Gustav Nebel, Lars Peter Kvist, Jerome K. Vanclay, Hector Vidaurre Dec 2000

Forest Dynamics In Flood Plain Forests In The Peruvian Amazon: Effects Of Disturbance And Implications For Management, Gustav Nebel, Lars Peter Kvist, Jerome K. Vanclay, Hector Vidaurre

Professor Jerome K Vanclay

Forest dynamics were studied from 1993 to 1997 for individuals > 10 cm DBH in nine 1 ha permanent sample plots. They were established in natural flood plain forests located on the lower Ucayali river in the Peruvian Amazon. After inventories of three plots in each of three forest types, a light and a heavy felling treatment were applied to each of the two plots, while a third plot was kept untreated. Average annual stem mortality and recruitment rates in the untreated plots were among the highest observed in neotropical rain forests: mortality 2.2-3.2% per year, recruitment 3.0-4.6% per year. Dead …
