Research progress on influencing factors of characteristic flavor compounds formation in black tea

This article summarized and analyzed the main factors affecting the formation of flavor compounds in black tea from 3 aspects: tea tree variety, planting environment, and processing technology. In terms of tea varieties, the genetic characteristics of different tea plant cultivars were found to shape the specific aroma profiles and flavor styles of black tea. Regarding the growing environment, altitude influenced tea plant metabolism through diurnal temperature variations, with black tea grown at higher altitudes(above 800 m)generally exhibiting superior flavor. Light quality and photoperiod, were shown to activate specific enzyme systems, promoting the synthesis of theaflavins and the formation of aroma precursors such as esters. Soil pH(optimal range 4.5-5.5), nutrients(e.g., potassium, phosphorus, magnesium), and microbial communities jointly regulated root development and secondary metabolism in tea plants, directly affecting the content and ratio of flavor compounds such as tea polyphenols. In terms of processing techniques, key processing techniques such as withering, rolling, fermentation, and drying are used to synergistically regulate the flavor compounds of black tea. Optimal combination of suitable process parameters (e.g., withering moisture loss rate of 60%-65%, rolling duration of 40-60 min, fermentation temperature of 25 ℃)was found to improve the color, aroma, taste, and storage performance of the tea infusion. The synergistic effect of tea tree variety, planting environment, and processing technology helps to stabilize and improve the flavor compounds of black tea, thereby enhancing its quality.
