Abstract

Tea conventionally is tested by human sensory panel called Tea Tasters, which assign quality scores to different tea samples. This paper reports a method of the reliable measurement and correct classification of Anxi Tieguanyin tea in Fujian province based on a kind of electronic nose (E-nose): PEN3(Portable Electronic Nose Version 3.0). With the help of the E-nose, we analyze various grades of different kinds of tea samples by using the popular method of separation, like PCA and LDA. Experiments show that the method proposed in this paper has outstanding performance and high efficiency.
