Abstract

Akpi (Ricinodendron heudelotii) is a semi-deciduous plant species indigenous to the coastal nations of West Africa. Its kernels are rich in nutrients and bioactive compounds. In this article, we performed a nutritional characterization and a phytochemical composition of defatted kernel flours from Ricinodendron heudelotti that were grown in six different regions of Cote d’Ivoire. Classical analytic methods were used to determine the chemical composition. There were significant differences between the samples for all the parameters studied; in addition, both the locality of production and the Ricinodendron heudelotii seed kernels extraction systems showed a noteworthy influence on the mineral and element composition of the defatted flours. The samples were also rich in protein (47.0–61.3%) and energy (330.4‒339.2 kcal/100 g). Magnesium (12.0–40.0%) was found to be the predominant mineral. Polyphenols (216.6–403.9 mg/100 g) and oxalates (714.7–972.9 mg/100 g) were the main phytochemical compounds identified. The consumption of defatted kernel flours from Ricinodendron heudelotti may contribute relatively high intake levels of protein, carbohydrate, and mineral macro- and micronutrient (K, Mg, Ca, Mn, and Fe). By performing principal coordinate analysis, the multidimensional scaling plot classified the defatted flours according to the kernel extraction into four main extraction systems: Bondoukou-Lakota-Vavoua diagram, Agboville1 diagram, Divo diagram, and Agboville2 diagram.
