  • 1. F.D UGESEI, K. P. BAIYERI2 & B.N. MBAH2 1 Department of Crop Production, University of Agriculture, Makurdi, Nigeria2 Department of Crop Science, University of Nigeria, Nsukka, Nigeria
  • 2.  Shea fat an important product from the shea tree. Has different uses: Illumination Bone setting Food industry Cosmetic industry
  • 3. BACKGROUNDFatty acid composition determines end use of shea fat:Hard butter – chocolate industrySoft butter – cosmetic industryNot much information about fatty acid variation across Nigerian shea belt.
  • 4. Objective Determination of fatty acid composition of shea fat across the Nigeria savannah.
  • 5. MATERIALS AND METHODS Samples collected from 9 locations across the savannah.o Ilorin, Lokoja, Makurdi, Akwanga, Minna (Southern Guinea Savannah)o Jalingo, Kachia (Northern Guinea Savannah)o Yola and Kano (Sudan Savannah) 15-25 trees sampled per location. Fat extracted with petroleum ether. Fatty acid determination by gas chromatography.
  • 6.  Analysis of variance Mean separation by DNMRT
  • 7. Table 1.

  • 9.  Stearic acid: 45.1 - 49.7% Oleic acid: 37.2 – 43.4% Linoleic acid: 5.8 - 7.4% Palmitic acid: 3.7 - 5.4% Stearic+ Oleic + Linoleic + Palmitic acid: 97.1 – 99.3%
  • 10. CONCLUSION Nigerian shea fat dominated by stearic acid. The shea fat most suited for the food industry.
  • 11.  More populations could be sampled to get more information on butter fatty acid composition. Could help in easy sourcing of butter for the different end uses.
  • 12. KEY REFERENCEUgese, F. D., Baiyeri, K. P. and Mbah, B.N. 2010. Fatty acid profile of the fat ofshea butter tree (Vitellaria paradoxa C. F.Gaertn.) seeds obtained from the savannaof Nigeria. Forests, Trees and Livelihoods19: 393-398
