摘要:分析景迈山古茶林普洱茶的产品质量。以不同贮存年份、不同季节的景返山古茶林普洱茶为研究对象，检测理化指标、重金属、农药残留，根据GB/T 22111-2008《地理标志产品普洱茶》、GB 2762-2017《食品安全国家标准食品

中污染物限量》、GB 2763-2016《食品安全国家标准食品中农药最大残留限量》、NY 659-2003《茶叶中铬、镉、汞、砷及氟化物限量》、NY/T288-2012《绿色食品茶叶》的标准要求，分析景迈山古茶林普洱茶的产品质量。景迈山古茶林普洱茶水分含量为X3 %~9.5 %，灰分含量为4.7 %~6.1 %，水浸出物含量为47.2 %~51.5 %，茶多盼含量为23.2 %~24.8 %，粗纤维含量为9.3%~11.5%，可溶性糖含量为3.7%~5.4%，游离氨基酸含量为1.9%~3.0%，铬含量为0.19111"]^~

1.21 mg/kg，锅含量为 0.016 mg/kg~0.269 mg/kg，钟含量为 0.00~0.20 mg/kg，氟含量为 31.0 mg/kg~88.1 mg/kg，采为未

检出，销含量为 3.86mg/kg~10.33 mg/kg，始含量为 0.03 mg/kg~0.65 mg/kg，稀土氧化物总量为 0.224 mg/kg~1.177 mg/kg，48种农药残留项目均为未检出。景迈山古茶林普洱茶理化指标、重金属、农药残留符合国家标准要求，其产品质量安

全可靠。
