The process variables pressure, temperature and particle size were studied for optimization of linoleic acid by response surface methodology following a Box-Behnken design of experiments. The results indicated the effect of extraction condition on linoleic acid of the extracts produced SC-CO2 gave the different effect. But, Analysis of the variance of the data indicated that there was no statistically significant difference between the other sample. Although there was greater variation within the sample, there was still no statistically significant effect of temperature and pressure on the extraction. The optimum conditions for linoleic acid yield from Swieteniamahagoni seed within the experimental range were found to be pressure of 29.02 MPa, a temperature of 67.88°C and particle size 0.75 mm, and the predicted linoleic acid was found to be 34.91%. © Published under licence by IOP Publishing Ltd.
