Studying at Kasetsart University Faculty of Science and Engineering Department of Applied Chemistry in between training classes and my friends given the mini-projectors with friends. We do Extraction of Capsaicin from chili. I was served by The experimental design For information and research to ensure the reliability of our results. We must do everything From the planning stage Chemical preparations The device uses trial Results of the experiments and present to the class. I learned a new experience. Not only in textbooks I have helped friends design experiments for reporting results. The results of that experiment. Substance capsaicin in chili silk. By analyzing the functional group outlawed group. And accept the opinions of friends on the team. We must work together, as we now have to choose the chemicals used to extract the capsaicin.
