摘要
目的:通过对梵净山5种抹茶适制茶树品种的抹茶理化成分含量进行分析,筛选出在梵净山区域适制抹茶的最优茶树品种。方法:以梵净山区域种植的‘金萱’‘薮北’‘龙井43’‘浙农113’‘香山早’5个茶树品种分别试制夏季抹茶,对试制抹茶的游离氨基酸、叶绿素、茶多酚、咖啡碱、蛋白质含量进行检测,并进行感官审评和比较分析。结果:5个供试品种中,‘薮北’的游离氨基酸含量最高,为3.30%;‘香山早’的叶绿素含量最高,为0.97%;‘香山早’和‘浙农113’的蛋白质含量最高,均为14.00%‘;金萱’的茶多酚和咖啡碱含量最低,分别为13.30%和3.11%‘;金萱’的感官审评评分总分值最高。结论:结合对高品质抹茶理化成分的要求以及综合感官审评结果来看,在梵净山区域种植加工抹茶‘,金萱’品种的适制性最好。
Objective:To analyze the physicochemical composition of matcha from five matcha suitable tea tree varieties in the Fanjing Mountain,and identify the optimal tea tree variety for matcha production.Methods:Summer matcha was prepared from five tea tree varieties grown in the Fanjing Mountain,namely Jinxuan,Yabukita,Longjing 43,Zhenong 113,and Xiangshanzao.The free amino acid,chlorophyll,tea polyphenol,caffeine,and protein content of the prepared matcha were detected,and sensory evaluation and comparative analysis were conducted.Results:Among the five tested varieties,Yabukita had the highest free amino acid content,at 3.30%.Xiangshanzao had the highest chlorophyll content,at 0.97%.Both Xiangshanzao and Zhenong 113 had the highest protein content,at 14.00%.Jinxuan had the lowest tea polyphenol and caffeine content,at 13.30%and 3.11%,respectively.And Jinxuan had the highest total score in sensory evaluation.Conclusion:Based on the requirements for the physicochemical components of high-quality matcha and the comprehensive sensory evaluation results,Jinxuan variety is the most suitable for the production of matcha.
