Africa produces approximately 1,760,000 metric tons (MT) of raw shea nuts a year, and historically, most of this stayed within the African continent to supply domestic demand. The shea export market traditionally traded raw shea kernels rather than shea butter or other finished products.
How are shea nuts processed?
Subsequently, the nuts are processed by boiling, roasting, or sun-drying. Boiling in water prevents the shea seeds from germinating and prevents hydrolytic degradation of the extracted shea butter. The boiled shea nuts are sun-dried, and then the dried shea nuts are cracked to obtain the kernels.
How is shea oil extracted?
As a result, many shea producers are adopting more mechanized solutions to improve quality and yield. Larger processors use mechanical extraction equipment to recover more oil efficiently. Screw press expellers physically crush the shea kernels to squeeze out shea oil from the solid meal, which exits the expeller as a cake.
Where are shea nuts produced in Burkina Faso?
The Sissili and Ziro provinces are the most important production centres. Further, shea nuts are the country’s third most important export after cotton and livestock. Since both shea nuts and shea butter are exported in huge quantities from Burkina Faso, their quality is extremely important.
How is shea butter extracted?
Extraction of shea butter from shea kernels can be done via either water extraction i.e. boiling with water, mechanical extraction, solvent extraction, or a combination of these processes. The traditional method of how shea butter is made involves water extraction – boiling the shea kernels with water and skimming off the released oils.
What is the shea butter export market?
The shea export market traditionally traded raw shea kernels rather than shea butter or other finished products. However, as shea applications have evolved and processing methods have improved, shea butter exports have increased as producing countries invest in more advanced equipment.
