(b) roma The aronia of green tea has been identified as consisting of fresh/ flowery notes, derived from green leaf components, and roast notes derived from compounds produced during firing. Despite the lack of a fermentation, many of the compounds producing the the fresh/flowery notes CTable 4.8 in green tea are also important in black tea. Linalool and, to a lesser extent, geraniol and Z-3-hexenyl hexanoate are largely responsible for flowery notes, while Z3- hexenol and its esters and E-2-hexenal are important contributors to the fresh aroma. These compounds are formed by oxidative ge of degradation of leaf lipids(see Figure 4.10, page 183).
