Variability in Balanites aegyptiaca var. aegyptiaca seed kernel oil, protein and minerals contents between and within locations


By Elfeel A.A.


Balanites aegyptiaca, deep rooted arid zone tree has a very wide natural range. The tree is valued for its fruits and seeds. The seed kernel is rich in oil, protein, minerals and edible as snacks after boiling. The wide range under which this species is occur suggests high pattern of variation among and within locations. The aim of this study was to assess the variability in seed kernel chemical contents between locations and individual trees with locations. Seed kernel from three distinct ecological zones in Sudan and individual trees within each zone were analyzed for minerals (N, P, K, Ca, Mg and Fe), oil and protein contents. The results showed a very high significant variation in all seed kernel chemical contents analyzed among and within locations. The oil content range from 50% to 20%, while protein varied from to 37% to 27%. The study revealed that Balanites seed kernel chemical content was remarkably variable among and within locations, that should be considered in conservation, domestication and improvement plans for this tree
