Composition and balance of the analytical fractionation of desert date (Balanites aegyptiaca L.) seeds harvested in Senegal

The desert date (Balanites aegyptiaca L.) can be one of the most common trees in Senegal. Thus, the objective is to carry out an analytical fractionation of these seeds to consider prospects for valuing the different constituents and a diagram of fractionation processes. The physical characterization of the seeds made it possible to know the fruit-seed and kernel-hull proportions. The chemical composition of the seeds...
