Summary: | PurposeThis review provides an overview of the applications of Bambara groundnuts in various food products. The genetic diversity, physical properties and chemical compositions of the crop are also elucidated.Design/methodology/approachThis paper critically reviewed the physicochemical properties and applications of Bambara groundnuts from recent literature.FindingsBambara groundnut (Vigna subterranea) is a drought-tolerant crop from West Africa that contains not only carbohydrates and fats but is also high in protein. The cultivars of Bambara groundnut can be distinguished by the colours of seeds, which range from red, blue-eye, brown and black-eye. Bambara groundnuts contain carbohydrate (57–67%), protein (15–25%), fat (4–8%), fibre (1.4–1.5%) and ash (2.9–4%). As a percentage of protein, the essential amino acids, lysine, methionine and cysteine are relatively high in Bambara groundnuts. Meanwhile, linoleic, palmitic and linolenic acids are the fatty acids present in this crop.Practical implicationsSeveral studies have shown that Bambara groundnuts can be used as fat substitutes, emulsifiers, water binders, bulking agents and thickeners due to its water and oil absorption properties, gelling, pasting, emulsifying and foaming abilities. Bambara groundnuts are used in the development of many intermediate or final products like flour blend, cookies, bread and fermented milk. It has a positive impact on the overall proximate, functional, mineral and amino acid profiles of the food products.Originality/valueDespite its high nutrient density, Bambara groundnuts are an underutilised legume due to unavailability and lack of knowledge among consumers on its benefits. There is a need to promote the use of Bambara groundnuts as a future food. |
