Evaluation of Nutrient Parameters of Selected African Accessions of Bambara Groundnut (<i>Vigna </i><i>subterranea </i>(L.) Verdc<i>.</i>)

Abstract

Developing countries, especially in Africa are facing challenges of malnourished conditions and food insecurity generally. Nutrients, being components of food ingredient required for survival, normal body function and satisfying the physiological and dietary requirements of the body metabolism [38]. Hence, for meaningful growth and developments in man, the type and amount of nutrients intake and its rate of absorption or level is crucial. However, much emphases and consumption pattern in Africa had been on common or routine food crops like rice, common beans, cassava, maize e.t.c., resulting in the reduced utilisation of other plant species, termed neglected and under-utilised species (NUS), like Bambara groundnut. Selected accessions of Bambara groundnut (Vigna subterranea (L.) Verdc), assembled at the International Institute of Tropical Agriculture, IITA, Ibadan, Nigeria were analysed for important nutrients parameters including moisture content, carbohydrate, protein, crude fibre, total sugar, fat, starch, ash and minerals, based on standard and established protocols at the Crop Utilisation laboratory, IITA, Ibadan, Nigeria. Moreso, samples were sent to the South African grain laboratory, the Willows, South Africa, for the determination of free and essential amino acids using HPLC and UPLC conditions. Results revealed that accessions TVSu -1235, TVSu -1231, TVSu -1205, TVSu -729 and TVSu -1824 could be regarded as high nutrients varieties, while TVSu -1744, TVSu -553 and TVSu -922 are medium nutrients type, while the remaining accessions falls below the medium nutrient range, among these lines of Bambara groundnut evaluated. The protein values has a range of 15.88 ± 0.005 g / 100 g for TVSu -1202 to 24.91 ± 0.011 g / 100 g for TVSu -1231; while their carbohydrate content ranges from 42.77 ± 0.001 g / 100 g for TVSu -1202 to 62.76 ± 0.223 g / 100 g for TVSu -1744.

Variations of Nutrient and Antinutrient Components of Bambara Groundnut (Vigna subterranea (L.) Verdc.) Seeds

“…erefore, it is expected that BGN should contain a high amount of carbohydrate. In this study, the carbohydrate content of 58.34% is similar to the result reported in the study of Atoyebi and Osilesi [30] (range of 42.77%-62.76%) and higher than 50.2% reported by Yao and Kouassi [7]. e higher the below 25%, is similar to that obtained by Nti [33], who reported a range of 19.3% to 27.1%, and Sirivongpaisal [34], who reported 15.48% protein content.…”

Bambara groundnut: an exemplar underutilised legume for resilience under climate change

“…Processing of bambara groundnut into flour (although HTC can affect milling) and its use as a full or partial substitute is one approach to reduce the HTC characteristics. A range of products and lines have been developed and evaluated (Ijarotimi and Esho 2009;Atoyebi et al 2017;Feldman et al 2019), as well as the packaging of industrially cooked seed into cans (Zimbabwe and Ghana, now discontinued) or vacuum sealed packets (Ghana), so that seed can be incorporated into food without the limitation imposed by cooking, for middle class consumers, at least. However, for most small-scale farmers, where bambara groundnut is a nutritional food security crop, reducing the components of HTC could be a significant advantage and is associated with traditional uses (e.g., in Zimbabwe; Mubaiwa et al 2018).…”

GGE Biplot Analysis of Genotype × Environment Interaction and Yield Stability in Bambara Groundnut

“…Reports have emerged that it can be used in the treatment of diseases such as diarrhea [2]. The seeds are rich in protein, carbohydrates, fat, mineral content, and fiber [3,4]. BGN is believed to be the most resilient to drought among grain legumes [5,6].…”
