Comparative study of the nutrients in the voandzeia subterranea seeds (var of nkamba and djambala)

The objective of the study is to compare the composition of nutrients on two cultivars of voandzou seeds. The seeds of voandzou we studied come from the locality of Nkamba South of the DR Congo and in the town of Djambala precisely in the North of Congo Brazzaville. Biochemical and physicochemical seeds characteristics were evaluated to determine the nutritional value of the seeds of this legume and its conservation. The results of the analysis indicated that content in humidity of both cultivars have revealed (12.08±0.19% for seeds of Nkamba against 10.85±0.07% for seeds of Djambala); ash content however shows (4.3±0.35% for seeds of Nkamba and 3.8±0.28% for seeds of Djambala); the seeds of voandzou lipid composition gives proportions of the order of 7.2±1.41% and 9.42±0.95% respectively for Nkamba and Djambala seeds.While the analysis on protein levels reveals (17.53±0.4% and 17.82±0.2% respectively for Nkamba and Djambala seeds) and the total carbohydrate contents (58.89±0.2% for seeds of Nkamba and 58.11±0.4% for seeds of Djambala). The order on the profile in fatty acid of both cultivars is similar and is as follows: C18:3 < C16:1 < C20:4 < C18:2 < C18:1 < C16:0.
