AbiC.F. 4200924In this study, press extraction conditions of shea butter were optimized. Response Surface Methodology (RSM) using the Doehlert experimental design has been employed in the optimization. The independent variables considered were roasting time (0-90 min), grinding size (1-5 mm squared mesh), cooking time (0-180 min) and cooling time (0-60 min). The linear combination and quadratic effects of these variables on extraction yield, acid value, peroxide value and absorbance at 440 nm were investigated. The extraction yield was significantly influenced by cooking time and roasting time (p<0.001). Acid value was significantly affected by all the mentioned parameters (p<0.05), whereas peroxide value was significantly influenced by grinding size (p<0.01), roasting time (p<0.001) and cooling time (p<0.01). The results revealed that the optimum conditions for extraction yield were grinding size 3.5 mm, cooking time 180 and 54 min cooling time.]]>Adoum, D.,19961996pp: 9296AFNOR (Association Francaise pour la Normalisation),19812nd Edn.,Brimberg, U.I.,1982597478Bas, D. and I.H.
