Effects of Extraction Methods on the Yield and Quality

The oil extraction method applied [47] and seeds/nuts moisture content prior to the oil extraction process [2], were the causes of the differences in the moisture content values of AOKO and the ...

The resulting oil–hexane mixture is later separated from the seed residue by filtration. The oil–hexane mixture is then heated to 68ºC to vaporise and recover the hexane to obtain the crude Shea Butter. The use of chemicals in the extraction process takes shea butter away from being a natural oil.

Effects of Extraction Methods on the Yield and Quality

Initial fermentation facilitates this process. Collected Shea fruits are buried in pits which cause the pulp to ferment and disintegrate and produced enough heat to prevent germination of the fruits. Drying of nuts: Traditional extraction method involves sun drying for 5-10 days to reduce the moisture content to about 15-30%.

Experimental study of shea butter extraction efficiency using

the oil was grey, and is referred to as grey oil in this article. In that case, the process was repeated to obtain clear oil. The shea butter extraction diagram is presented in Figure-1. Figure-1 shows three different oil extraction processes. The central part of the diagram (Branch B) presents the traditional butter extraction method, as

ing nuts/water mass ratio < 400 g/l of water were found to be optimum conditions for the extraction of shea butter. Keywords: shea nuts pretreatmen; response surface methodology; shea butter quality Shea [Butyrospermum parkii (G. Don) Kotschy or Vitellaria paradoxa Gaertn.] nuts are frequently used in Africa to extract oil called “shea butter”.

How shea butter is made: A complete guide to shea nut

Step 2: Shea butter extraction 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 ...

Shea Nuts Oil Expeller machine. Firstly the shea nut is subjected to mechanical extraction with the help of screw presses. The resultant cake containing 14 to 16% oil (butter) then is subjected to solvent extraction process. Apart from that, The shea nut preparation required is cooking and flaking purpose.

  • 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 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 is shea butter extracted in Ghana?
  • Extraction of shea butter is a major income generating activity in Ghana, particularly in the Northern Regions. It is estimated that about 80% of the shea butter produced in Ghana is processed by women using traditional aqueous extraction method. Commercial extraction using continuous screw press accounts for about 20% of production.
  • Why is solvent extraction method not used in shea butter extraction?
  • According to FAO and CFC (2002), solvent extraction method is not usually used in domestic and commercial shea butter extraction in developing countries due to the high costs involved, environmental problems and the lack of technical skills associated with it.
  • How are pre-treated shea nut substrates treated?
  • Three different pre-treated shea nut substrates: raw kernels, roasted kernels and shea nut paste from roasted kernels were subjected to treatment with three different industrial enzymes: lipase, pectinase and cellulase, separately and in combination for shea butter extraction.
  • How to extract butter from shea kernels?
  • The IMC method involves the use of a low pressure manual screw press to extract butter from shea kernels. The study established an optimum extraction temperature of 60 • C and moisture content of 12% at which butter extraction efficiency was between 65.9% and 68.5%.
