泾渭茯砖茶水溶性氟浸出量研究

The release of fluorine into Jinwei Fu-brick tea liquor during infusion

采用氟离子浓度计对茯砖茶水溶性氟的浸出量进行了研究,对不同茶水比、不同浸提时间、不同冲泡次数、不同冲泡温度进行水溶性氟含量检测,并对不同等级产品的水溶性氟含量进行研究。结果显示:不同处理方法,冲泡法的含氟量和水浸出含量均低于浸提法;氟含量和水浸出物含量呈现相同变化趋势且二者浸出呈现正相关;不同等级产品因原料的差异,氟含量存在一定差异。

This paper was researched on the water extracting content of fluorine in the Fu-Brick tea with different dispose about fluorinion concentration meter,researched on the content of fluorine about different ratio of tea and water,different brewing time,different brewing times,different brewing temperature,then discussed the water extracting content of fluorine with different grades production.The result showed that：for all the processing,the content of fluorine in brew way were lower than the extract way;the content of fluorine and water extract were present the same trend;and they present positive correlation;different grade products for raw materials,the differences between fluorine content there is some difference.
