| 摘 要： | 对春季不同时期安吉白茶制成的信阳毛尖茶的水浸出物、茶多酚、氨基酸、咖啡碱、叶绿素等化学成分与感官品质的关系进行了初步研究。结果表明,安吉白茶信阳毛尖茶的氨基酸含量随时间的推移呈逐渐降低的趋势,茶多酚、叶绿素含量呈逐渐增高的趋势;随时间的推移,安吉白茶信阳毛尖茶的鲜爽度呈逐渐下降的趋势,滋味浓度呈逐渐增加的趋势;由于叶绿素b含量呈逐渐增加的趋势,干茶色泽和汤色也呈逐渐变深的趋势。

Chemical Compositions and Organoleptic Quality of Xinyang Maojian Tea made by Anjibaicha in Different Periods of Spring |
| |
| Abstract: | The Relations of chemical compositions (water extracts, tea polyphenols, amino acid, caffeine, and chlorophyll, etc.) and organoleptic quality of Xinyang Maojian tea made by Anjibaicha in different periods of spring were researched. The results showed that with the postponing of plucking period, the content of amino acid was decreased. however, tea polyphenols and chlorophyll were increased. On the other hand, organoleptic quality of tasty and refreshing was reduced, the density of tea was increased. With the addition of chlorophyll, the color of tea and juices were deep gradually. |
