Abstract:

To explore the influence of different tea cultivars on the flavor quality of Qinggan tea,Qinggan tea was prepared from four main tea cultivars,Jiukeng,Longjing 43,Fudingdabai and Wuniuzao in Quzhou area,and the quality differences were compared based on sensory and biochemical analysis. The results showed that the Jiukeng cultivar had the best overall quality,with a sensory score of 92.2 points,a harmonious and long-lasting aroma,and a mellow and sweet taste. This variety has the highest content of water extract(35.64%)and free amino acids(4.05%),moderate ester/non-ester catechins,and a suitable polyphenol-to-amino acid ratio,which lays the material foundation for its excellent quality. It has revealed that tea tree cultivars play a key role in the formation of the flavor quality of Qinggan tea,providing a theoretical basis for the selection of high-quality raw materials for Qinggan tea.

Key words: tea cultivar, Qinggan tea, biochemical components, flavor quality
