We kneaded third-crop green tea and loquat leaves and prepared them by a firing process in order to manufacture a new fermented tea mix. Sensory testing was carried out and aromatic compounds were measured during the firing stage in order to investigate the effects of temperature and time on the tea product. The firing process did not alter the contents of the major aromatic chemicals in the tea mix. On the other hand, levels of (E,E)-2, 4-heptadienal, an unfavorable aromatic chemical found in low-grade tea leaves, decreased with increases in both temperature and time. Aromatic compounds increased only when firing was carried out at higher temperatures and for longer periods. The firing process does not typically enhance favorable flavors of third-crop teas. However, this study demonstrated that firing can enhance heat-induced aromatic compounds, thereby making it suitable for firstcrop green tea processing.
