Optimization of Solvent Extraction of Oil From Wild Bush Mango Seed

Four operating parameters of the solvent extraction of oil from seed of wild bush mango plant (irvingia gabonensis) using normal hexane as the solvent have been optimized by a composite design. A linear model was developed, and validated with diagnostic plots. The model was optimized numerically and the optimum conditions established were; temperature of 40 size of 2.05MM, time of 4hours and solvent volume of 300mls at a constant value of the sample dosage of 10grams. The predicted oil yield was 42.4167% at 0.767 desirability. There was a good correlation between the predicted and actual values.
