摘要
用差示扫描量热法(DSC)和热重法(TG/DTG)对同期采摘的不同原产地的茶叶进行了热分析研究。结果发现,不同产地的茶叶的热化学性质有明显差别。从加热失重、焓变和峰的位置可快速简便的鉴别不同产地的茶叶。
The thermal properties of different places of origin tea were studied by DSC method and TG method, which picked at the same period. Experiments found that the thermal properties of different places of origin tea are different obviously. It is easy to distinct the tea of different places of origin from the weight-lost, enthalpy and peak position.
