Thesis (MTech (Food Technology))--Cape Peninsula University of Technology, 2015.<br>The aim of this study was to characterise the physicochemical, rheological, prebiotic and emulsion stabilising properties of four varieties (black-eye, brown-eye, brown and red) of Bambara groundnut (BGN) extracted using the modified wet milling method. A relatively high yield of BGN dietary fibres was obtained with soluble dietary fibres (SDFs) ranging from 15.4 to 17.1% and insoluble dietary fibres (IDFs) ranging from 12.0 to 15.6%. Black-eye and brown-eye dietary fibres showed superiority in terms

The model is a stand-alone computer program written in Delphi 6 (Borland®). It uses climate data, landrace specific parameters and physiological relationships and runs on a daily time-st

Abstract:

Bambara groundnut (Vigna subterranea (L.) Verdc.) is an important underutilised legume crop, grown mainly by female subsistence farmers in Africa under traditional low input agricultural systems. Bambara groundnut is known as being of high nutritional value, as an atmospheric nitrogen fixer and to possess high levels of drought, pest and disease tolerance. Bambara groundnut is a predominantly self-pollinated crop and is grown as locally adapted landraces. These are expected to exist as non-identical inbred lines and are generally low yielding.

Abstract:

Bambara groundnut (Vigna subterranea (L.) Verdc) is an indigenous legume that is still cultivated in subsistence agricultural systems in sub-Saharan Africa, despite the lack of any major research effort until recently. The crop is cultivated from local landraces as there are no true varieties of the species bred for specific traits. The variable and hostile climates in the region mean that annual yields of most rainfed crops including bambara groundnut are far below their agronomic or genetic potential.

With the world population estimated to be nine billion by 2050, the need to exploit plant genetic diversity in order to increase and diversify global food supply, and minimise the over-reliance for food on a few staple crops is of the utmost importance to address food security challenges. Bambara groundnut (Vigna subterranea (L) Verdc.), is an underutilised legume indigenous to Africa, rich in carbohydrates, with reasonable amounts of protein.

Abstract:

Agricultural production is at the mercy of uncertainties driven by climate change, as a result of this most of the major and minor crops are under threat of crop failure due to the severity of its effects on ‘crop fertility’. Plant reproduction is regarded as highly sensitive to such climatic changes, especially under high temperatures stress. Therefore, a key strategy to adapt to ever-increasing global temperature is by improvement and promotion of underutilised crops, one such future crop and the main focus of our research is bambara groundnut (Vigna subterranea [L] Verdc.).

Bambara groundnut (Vigna subterranea [L.] Verdc.) is an under-utilized indigenous African legume crop which has substantial potential to contribute to food security in sub-Saharan Africa. The crop is well adapted to severe agro-ecologies and grows where other legumes may not survive. The seed is highly nutritious with an ideal balance of carbohydrate (55-72%), protein (18-20%) and fats (6-7% oil), which is particularly beneficial in balancing protein deficiencies in cereals. Also, the seed contains essential and non-essential amino acids of about 33% and 66%, respectively. These attributes mak

Abstract:

Issues surrounding water scarcity will become topical in future as global fresh water resources become more limited thus threaten crop production. Predicted climate change and increasing population growth will place more pressure on agriculture to produce more food using less water. As such, efforts have now shifted to identifying previously neglected underutilised species (NUS) as possible crops that could be used to bridge the food gap in future. Taro (Colocasia esculenta L. Schott) and bambara groundnut (Vigna subterranea L. Verdc) currently occupy low levels of utilisation in South Africa.
