Determination of Essential Mineral Content of Bambara Groundnut (Vigna Subterranea L.) Produced in North of Côte d’Ivoire

The aim of this study was to assess the mineral content of bambara groundnut seeds in the Northern regions of Côte d'Ivoire and evaluate their nutritional value. A total of 120 bambara groundnut samples were collected from five regions and categorized into seven cultivars based on seed coat color. The seeds were then analyzed at the Nutrition and Food Technology Laboratory of Félix Houphouet-Boigny National Polytechnic Institute using energy dispersive spectrophotometry. The analysis revealed the presence of macro elements, including potassium, sodium, magnesium, calcium, and phosphorus, with varying concentrations. The microelements zinc, iron, manganese, and copper were also found in the seeds. The contribution of these minerals to daily intake requirements ranged from 0.11% to 20.94%. However, zinc was found to have a higher need for adequate intake. These findings indicate that bambara groundnut seeds, regardless of cultivar, are a good source of essential minerals. Promoting the consumption of bambara groundnut could help address food security and poverty alleviation in the region. Furthermore, these results emphasize the importance of this underutilized legume in combating hunger and malnutrition in Africa.
