<br/><br/> This thesis presents a detailed response surface methodology study on the microwave assisted extraction of Ý-carotene from carrot peels. Unlike published research which utilized a modified domestic microwave oven, in this study, a controlled temperature microwave oven was used. Preliminary trials were applied to find the best heating procedure, then a full response surface methodology starting from the first order model passing by the steepest ascent line to the second order model was applied. Optimum conditions were determined and compared with published experimental results
