Abstract
Optimization of percentage of oil yield extracted from castor seed was carried out using response surface methodology and Box-Behnken design. Castor oil was extracted using solvent extraction with three different solvents; hexane, petroleum-ether and ethanol. The linear and quadratic effects of the two variables studied were most significant in affecting the oil yield. The maximum yield of oil extracted was 50.9, 49.0 and 59.5 % using hexane, petroleum ether and ethanol respectively as solvents and the optimum conditions were at a time of 3 h and an average particle size of 1 mm which were within the experimental domain. The model equations gave a good fit with the coefficient of determination of 0.9216, 0.9587 and 0.9005 for hexane, petroleum ether and ethanol, respectively, and hence the suitability of the response surface methodology for the optimization of percentage oil yields.
