中文摘要: 以浙江省丽水市群体种茶园中选育的两份紫化茶树品种丽紫1 号和丽紫2 号作为供试品种,以紫娟为对照,对茶树新梢色泽、色素含量进行测定,制作生化样、绿茶样、红茶样和白茶样,通过生化成分检测和感官审评进行多茶类适制性分析。结果表明丽紫1 号、丽紫2 号的新梢色泽分别呈紫红色和紫绿色,花青素含量分别为(5.59±0.07)、(4.44±0.06)mg/g。丽紫1 号、丽紫2 号的水浸出物、氨基酸含量显著高于对照,酚氨比、咖啡碱含量均低于对照。加工成不同类别茶叶后,绿茶中氨基酸和茶多酚含量最高,丽紫2 号绿茶氨基酸含量最高[(4.54±0.19)%],丽紫1 号绿茶茶多酚含量最高[(27.90±0.51)%]。红茶水浸出物含量最高,茶多酚含量最低;丽紫2 号红茶水浸出物含量最高[(47.86±0.58)%],同时茶多酚含量最低[(8.92±0.28)%]。绿茶和红茶中咖啡碱含量较高,白茶最低,丽紫1 号白茶咖啡碱含量最低[(2.87±0.16)%]。根据所有茶样感官审评总分,3 个品种制作绿茶、红茶、白茶均有较好的适制性。绿茶和红茶均以丽紫2 号感官品质最佳;丽紫1 号和对照制作白茶的总分稍高于丽紫2 号。
Abstract:Two purple tea varieties,Lizi 1 and Lizi 2,which were excavated from the large-scale tea garden in Lishui City,Zhejiang Province,were used as test varieties,and Zijuan was used for reference. The color and pigment content of tea buds were measured,and tea leaves were processed into biochemical samples,green tea,black tea,and white tea. The processibility of different tea varieties was analyzed through biochemical component detection and sensory quality evaluation.The results showed that the buds'color of Lizi 1 and Lizi 2 were purplish red and purplish green,and the content of anthocyanidin was(5.59±0.07)and(4.44±0.06)mg/g.The water extract and amino acid content of Lizi 1 and Lizi 2 were significantly higher than those of Zijuan.The phenol-to-ammonia ratio and caffeine content were significantly lower than those of Zijuan. After processing,the content of amino acids and tea polyphenols in green tea was the highest. The green tea made by Lizi 2 had the highest amino acid content,which was(4.54±0.19)%,while the green tea made by Lizi 1 had the highest tea polyphenols content,which was(27.90±0.51)%. Black tea had the highest content of water extracts and the lowest content of tea polyphenols. The black tea made by Lizi 2 had the highest content of water extracts and the lowest tea polyphenols content,which were(47.86±0.58)% and(8.92±0.28)%. Green tea and black tea had higher caffeine content,while white tea had the lowest caffeine content. White tea made by Lizi 1 had the lowest caffeine content,which was(2.87±0.16)%. According to the total sensory evaluation scores of all tea samples,the three varieties had good processibility for green tea,black tea,and white tea. Both green tea and black tea made from Lizi 2 had the best sensory quality.The total score of white tea made by Lizi 1 and Zijuan was slightly higher than that made by Lizi 2.
