Abstract:

The purpose of this study is to reveal the key aroma components and biochemical components which determine the ‘Cong flavor’ of Camellia sinensis ‘Fujian Shuixian’. The volatiles and biochemical compounds in different fragrance types of C. sinensis ‘Fujian Shuixian’ were detected using GC-IMS and HPLC, respectively. A total of 38 volatile compounds were identified. Pentanal and hexanal are the characteristic aroma components of C. sinensis ‘Fujian Shuixian’ with woodiness scent; 3-hexen-1-ol and linalool are the characteristic aroma components of C. sinensis ‘Fujian Shuixian’ with moss flavor; and 2-pentyl furan and benzaldehyde are the characteristic aroma components of C. sinensis ‘Fujian Shuixian’ with reed leaf flavor. In addition, the increase of water extract and caffeine content could have a significantly positive effect on the improvement of ‘Cong flavor’ quality, whereas the increase of ester catechin content could reduce the taste quality of C. sinensis ‘Fujian Shuixian’. Particularly, the reduction of catechin index has a positive impact on the quality improvement of ‘Cong flavor’. Overall, this study provides a technique of rapid quality discrimination of C. sinensis ‘Fujian Shuixian’ and a scientific basis for establishing the enterprise standard.
