| 摘 要： | 通过对烘焙温度、烘焙时间和物料量的控制,分别建立武夷冻茶烘焙工艺中失水率和叶绿素含量的数学模型,并分析了失水率和叶绿素含量之间的相关性.结果表明:在烘焙因子投入水平下,烘焙因素与失水率和叶绿素变化具有较高的相关性.随着烘焙时间的变化,失水率和叶绿素含量之间呈负相关;随着烘焙温度的变化,失水率和叶绿素含量之间呈正相关.试验结果表明,数学模型可以动态地控制水分和叶绿素的变化.

| Abstract: | The mathematic model relating to the changes of water and chlorophyll content in Wuyi frozen tea is established with the effects of drying factors,including temperature,time and weight of tea.And the relationship between dehydration rate and chlorophyll content was analyzed on the basis of these models.The results showed that the dehydration rate and chlorophyll content in tea was highly related to the drying factors.There had a negative correlation between dehydration rate and chlorophyll content in seriate temperature,and a positive correlation in seriate time when other factors were set on zero level.The proof test and application also showed that the mathematics models could be used to control the changes of water and chlorophyll content dynamically during drying process. |
