7.10. Baobab Oil

INCI Name: Adansonia digitata (Baobab) oil

Baobab, Adansonia digitata popularly known as the upside down tree, a long–lived deciduous tree of the family Malyaceae occurring in areas barren and dry in southern Africa, Australia and Madagascar (Zimba et al., 2005; Osman, 2004; Wren and Stucki, 2003; Sidibe and Williams, 2002; Maranz et al., 2008). Within eight species A. digitata, is distinguished by a number of local types differing in life, size, quality of fruit and vitamins content (Gebauer et al. , 2002). Virtually all parts of the baobab trees are used (Sidibe and Williams, 2002). Bulbs, twigs, fruits, seeds, leaves and flowers are used as ingredients in traditional dishes (Nnam and Obiakor, 2003; Nordeide et al., 1996), while the fibers from the bark are used for the manufacture of ropes and chains (Sidibe and Williams, 2002).

The traditional method of obtaining oil from the seeds of the baobab tree is to remove the seeds with thorns, grinding, cooking and then cooling and harvesting of oil above the water layer (Zimba et al., 2005; Osman, 2004; Maranz et al., 2008). In an industrial baobab seed oil is produced primarily by cold pressing (Zimba et al., 2005; Wren and Stucki, 2003).

Oil from the seeds of the baobab tree is called a hidden secret of Africa. It has a yellow color, is edible and has a delicate nutty flavor (Wren and Stucki, 2003; Bird, 2003). It is an excellent source of mono– and poly–unsaturated fatty acids. The oil consists of 15–31% saturated fatty acids, 37–82% monounsaturated fatty acids and 3–31.7% polyunsaturated fatty acids. The main fatty acid is oleic acid C18:1 n– 9 (35.8%), linoleic C18:2 n–6 (30.7%) and palmitic C16:0 (24.2%) (Table 6) (Osman, 2004).

Processed seeds are used in treating stomach and kidney. In South Africa, where trees are common, oil is used for cooking and as a cosmetic (Zimba et al., 2005; Bird, 2003). The seeds are eaten as a peanut, and as a coffee substitute. They can be eaten fresh, dried or roasted (Sidibe and Williams, 2002).
