应用离子选择电极法测定了花茶在不同浸泡条件下可没出氟的含量。结果表明:花茶可浸出氟的含量与浸泡温度、浸泡时间、浸泡次数有关。
The ion-selective electrode method was used to determine the content of FFA in different immersion conditions. The results showed that the content of tea extractable fluorine was related to the soaking temperature, soaking time and soaking times.
