Abstract

The aim of this study was to investigate the oil extracted of seeds of different trees of Allanblackia floribunda. The analysis of the seeds of Allanblackia floribunda Oliv. permitted to value their oleaginous character and to establish their compositions in fatty acids and in triacylglycérols in order to promote the valorization of these seeds by diversifying lipid profiles of oils in the Congo basin. These seeds are very oleaginous with oil contents ranging between 60 and 65% after 5 h of extraction in the cyclohexane, permitting to classify Allanblackia floribunda Oliv. In the group of the oleaginous plants with high content in fat matter. The seeds of the seven studied trees show some contents in stearic acid superior to 60%, added to contents of more than 30% of oleic acid, the oil of the seeds of Allanblackia floribunda is characterized therefore by a predominantly saturated profile. The nutritional interest of this source of lipids resides in the neutrality of the stearic and oleic acids (98% cumulative percentage) opposite the blood lipids. The oils of Allanblackia floribunda Oliv. studied, whatever the tree highlights a stability of the profile in TAG of this species leading to fat with a very simple TAG profile which reduces to only one type of TAG constituting more than 88% of the total content in TAG for SSO.

Keywords:
