  • 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.
  • How much oil is left behind in a Shea?
  • This inefficient, inexpensive extraction method leaves about 23% of the fat behind, only yielding about 35% of the oil. 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.
  • How many raw shea nuts are produced in Africa?
  • 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 much is a shea nut worth?
  • The annual worldwide export of shea nut from Africa is 350,000 MT of kernels with a market value of approximately $120 million to producing countries. The multifunctional properties of the shea butter depend strictly on its compositional properties: the peroxide value, moisture content, free fatty acid level and the insoluble impurities.
  • Does shea butter need solvent extraction?
  • For these reasons, solvent extraction is generally not preferred for shea butter extraction—especially in food and cosmetic markets where consumers seek natural, organic ingredients. What is shea oil? Traditional water extraction, mechanical expeller pressing, and solvent extraction yield shea butter.
  • What are shea nuts used for?
  • Shea nuts are usually processed and used for Shea butter extraction which have wide applications in the cosmetic, pharmaceutical and food industries . It is used as cocoa butter equivalent (CBE) and enhancer in chocolate manufacturing, providing greater stability and extended shelf life [6,9]. ... ...
