Study of Laurie tea processor black tea mixing fermentation using the simplex centroid design method

Broken black tea (BBT) is the most consumed black tea in the world. Laurie tea processor black tea (LTP-BT) is one of the most important categories of BBT. In this study, the fresh leaves of three tea plant cultivars including Golden Peony tea, Yunnandaye, and Fuding Dabai were blended to process LTP-BT using the simplex centroid design. Using gas chromatography-mass spectrometry and high-performance liquid chromatography, the differences in volatile and non-volatile components of LTP-BT under different formulations were analyzed.
