中文摘要:

      目的 通过深圳市市售茯砖茶氟含量的现状, 探究茯砖茶氟含量超标的成因。方法 在深圳市全市范围内采集75份茯砖茶, 对每份样品进行氟含量的检测, 按照GB 19965—2005《砖茶含氟量》判定是否合格。结果 所分析的75批次茯砖茶中, 50批次氟含量低于GB 19965—2005的限值(300 mg/kg), 合格率为66.7%, 检测结果平均值为349 mg/kg。结论 深圳市市售茯砖茶的合格率高于全国饮茶型地氟病监测点总的砖茶氟含量合格率, 茯砖茶氟摄入过量风险较低, 但仍存在部分不符合国家强制标准的产品在售, 部分茯砖茶的氟含量较高与其原材料的选取有关, 建议砖茶的相关产品标准明确氟含量的限量要求。

英文摘要:

      Objective To explore the causes of excessive fluoride content in Fuzhuan tea through the current situation of fluoride content in Fuzhuan tea in Shenzhen. Methods The 75 samples of Fuzhuan tea were collected throughout the city of Shenzhen, and the fluoride content of each sample was tested to determine whether it was qualified according to GB 19965—2005 Fluoride content of brick tea. Results Among the 75 batches of Fuzhuan tea analyzed, 50 batches had fluoride content lower than the limit of GB 19965—2005 (300 mg/kg), with a pass rate of 66.7% and an average test result of 349 mg/kg. Conclusion The qualified rate of Fuzhuan tea sold in Shenzhen is higher than the total qualified rate of fluoride content in brick tea from the national monitoring points for fluoride disease in tea drinking areas. The risk of excessive fluoride intake in Fuzhuan tea is relatively low, but there are still some products on sale that do not meet the national mandatory standards. The high fluoride content of some Fuzhuan tea is related to the selection of its raw materials. It is recommended that the relevant product standards for brick tea clarify the limit requirements for fluoride content.
