We lead the manufacturing technique and the quality of Taiwanese oolong tea in the world. However, the manufacturing process of the oolong tea is complicated and it is hard to make oolong tea by automated machine by now. Oolong tea production is dependent on man, because of both the skill and the work. That makes the limitation of producing high-quality oolong tea in the amount. To improve the oolong tea producing potential, establishing an artificial intelligent judging system of the tea manufacturing process is needed for the automated oolong tea manufacturing system. In the oolong tea manufacturing, the master decided each process mostly by smelling the change of the odor in the traditional way. That is the central idea of our plan to develop an artificial intelligent judging system by sensing the volatiles during the manufacturing process. The two major processes affecting the oolong tea quality are the shaking (stirring) and firing. The good timing control of these two processes is important and essential to the artificial intelligent judging system development. In this study, we will analyze the volatility of the manufacturing process and tea quality to find out the potential volatile compounds as the index of the developing high sensitive electronic nose system. This electronic nose system will be monitoring the change of the volatiles during oolong tea-producing. By integrating the key volatile index of the shaking and firing and the volatile monitoring system, we will create a new automated timing judging system for the tea manufacturing process. The new system “volatile artificial intelligent monitoring in oolong tea manufacturing” will be adjusted and verified by the official tea manufacturing contest. The achievement of this study is to develop a new technique for automated oolong tea manufacturing and to reach a new milestone that is high quality, high quantity, and low labor demand in Taiwan oolong tea.茶葉發酵自動化製茶電子鼻攪拌時機炒菁時機茶葉品質tea fermentationautomated tea manufacturingelectronic noseshaking timingfiring timingtea quality
