The E-nose Dataset of Maofeng green tea and Maojian green tea in our article: A Machine Learning Method for the Fine-Grained Classification of Green Tea with Geographical Indication Using a MOS-Based Electronic Nose

Twelve green tea (six Maofeng teas and six Maojian teas) from different geographical origins are used in our study, including Huangshan Maofeng (HSMF), Yandang Maofeng (YDMF), Lanxi Maofeng (LXMF), Qishan Maofeng (QSMF), Meitan Maofeng (MTMF), Xinyang Maojian (XYMJ), Guilin Maojian (GLMJ), Duyun Maojian (DYMJ), Guzhang Maojian (GZMJ), and Ziyang Maojian (ZYMJ). The data is acquired by a commercial E-nose (PEN3, Airsense Analytics GmbH, Germany), with 10 MOS sensors in our laboratory.
