3 De Smet plants are processing shea nut
Origin
The sheatree is tall (15 to 20 m) and the trunk can reach 1 m diameter; it is existing on west african coasts and in Sudan.
It produces fruits of the size of a prune with a nut (the sheanut) enclosed in a red brown shell; the sheanut, on basis of 6-7% of moisture, contains 45 to 55% of vegetable butter, sheanut butter.
The pulp of the fruit do not really contain any fatty matters and ususally, it is manually separated from the nut after fermentation or sun-drying.
End uses
The nuts after separation from the pulp are decorticated by hand and the shea butter is extracted in the traditional way.
The exported shells are extracted in a single or double pressing followed by solvent extraction.
The shells are burnt and the pulp is edible.
