| 【目的】明确多茶类兼制高香茶树品系‘一路香’和‘叶来香’制茶品质及香气特征，加快茶树良种应用进程。【方法】以‘一路香’和‘叶来香’为原料，制成绿茶、乌龙茶、红茶和白茶，以‘黄旦’为对照，进行感官品质评价与香气组分差异研究。【结果】与‘黄旦’相比，‘一路香’和‘叶来香’制成不同茶类品质均不同程度提升。‘一路香’绿茶品质最优，带花香，主要以β-罗勒烯、己酸叶醇酯等为主。‘叶来香’乌龙茶品质最佳，花香显，以β-罗勒烯、苯乙醇、己酸叶醇酯等为主。‘一路香’与‘叶来香’红茶评分相当，均有花香，‘叶来香’红茶以香叶醇等花果奶香成分为主，‘一路香’红茶以水杨酸甲酯等清香幽长成分为主。‘叶来香’制成的白茶品质最优，呈现奶粉香，主要以香叶醇、(Z)-3-己烯醇等为主。【结论】‘一路香’与‘叶来香’均适制绿茶、乌龙茶、红茶和白茶，其中‘一路香’更适制绿茶和红茶，‘叶来香’更适制乌龙茶、红茶和白茶。 |

| Abstract: |
| 【Objective】The study aims to examine the quality and aroma characteristics of various tea types produced from tea varieties ‘Yiluxiang’ (YILX) and ‘Yelaixiang’ (YELX) and accelerate their application.【Method】Green tea,oolong tea,black tea,and white tea were prepared with YILX and YELX as raw materials and with ‘Huangdan’ as control.Sensory quality evaluation and aroma component of tea samples were investigated.【Result】The quality of green tea, oolong tea,black tea,and white tea produced from YILX and YELX showed varying degrees of improvement compared to ‘Huangdan’.The green tea produced by YILX was of the highest quality,characterized by floral fragrance and enriched with a high level of floral and fruity aroma components,including β-ocimene and (Z)-3-hexenyl hexanoate,among others.Oolong tea made from YELX had the best quality with distinct floral fragrance and the highest content of various floral and fruity aroma components, including β-ocimene,phenylethanol,and (Z)-3-hexenyl hexanoate.The sensory scores of the black teas made from YILX and YELX were comparable,as both exhibit floral aromas.While YELX aroma quality was mainly composed of flower,fruit,and milk aroma components such as geraniol.YILX was mainly composed of fragrant and long-lasting components such as methyl salicylate.Teas made from YELX was of the highest quality,with a milk powder fragrance and the highest content of aroma components such as geraniol,(Z)-3-hexenol and so on.【Conclusion】Both YILX and YELX are suitable for making green tea, oolong tea,black tea,and white tea.YILX is better suited for making green tea and black tea,while YELX is more suitable for making oolong tea,black tea,and white tea. |
