Abstract: After appropriate roasting, burdock produced a kind of flavor similar with that of coffee. According to the results above and differences of individual sense and taste, the flavor most like coffee was obtained after baking at an appropriate temperature. Through the experimentation ,we found that before we baking the burdock we should to dry it in the oven for 2 hours at the temperature of 100℃.Then we baked the burdock at the temperature of 200℃ for 4 min .In this way we can obtain the best flavor. Then the flavor was determined through GC-MS and the results were compared with the components of coffee flavor. In addition, the producing process of burdock flavor was also studied to some extent according to that of coffee.

Key words: burdock, flavor, GC-MS
