云南省野生食用菌中总砷含量调查
目的 全面了解云南省野生食用菌中总砷污染水平, 为开展云南省野生食用菌中砷污染状况的评价和预警提供基础数据。方法 收集30种野生食用菌品种, 按GB/T 5009.11-2003《食品卫生检验方法理化部分 总砷及无机砷的测定》, 用原子荧光光谱法测定所采集的野生食用菌中的总砷, 根据GB 2762-2012《食品安全国家标准 食品中污染物限量》进行评价。结果 30种171件新鲜野生食用菌中总砷含量范围为<0.05~4.91 mg/kg, 其中楚雄松茸的总砷含量最高, 为4.91 mg/kg; 野生食用菌的平均超标率为11.1%, 而松茸超标率为100%。结论 本次调查选取的野生食用菌中大部分样品的总砷含量达到国家标准要求, 应加强对超标野生食用菌的监测, 同时也要开展对野生食用菌干制品中污染物的检测, 以确保食品安全。
Objective To fully understand the pollution of total arsenic in wild edible fungi in Yunnan province, and provide a reliable basis data for the evaluation and early warning of arsenic pollution in wild edible fungi. Methods A total of 30 kinds of wild edible fungi were collected, the content of total arsenic in wild edible fungi were determined by atomic fluorescence spectrophotometry, according to GB/T 5009.11-2003 Methods of food hygienic analysis, physical and chemical section-Determination of total arsenic and inorganic arsenic. The results were evaluated according to GB 2762-2012 National food safety standard-Limits of contaminants in food. Results The detection range of 30 kinds of 171 fresh wild edible fungi was <0.05~4.91 mg/kg, the highest content of total arsenic was Tricholoma matsuake in Chuxiong, which was 4.91 mg/kg. The over-standard rate of total arsenic was 11.1%, and the over-standard rate of Tricholoma matsutake was 100%. Conclusion The total arsenic content of most wild edible fungi in this investigation meet the national standard. It is necessary to strengthen the monitoring in edible fungi with unqualified results, and at the same time carry out the detection of contaminants in wild edible fungi dried products to ensure the food safety.
