中文摘要:

      目的 了解吉林省干制食用菌中重金属的含量水平。方法 在吉林省内10个地区的生产流通领域随机购买7个种类的干制食用菌, 共收集167份样品, 对样品中铅、镉、总砷及总汞4种重金属元素的含量进行测定, 根据GB 2762-2017《食品安全国家标准 食品中污染物限量》进行评价。结果 167份干制食用菌中重金属含量总超标率为3.6%。在7类干制食用菌中, 干制榛蘑中镉的平均含量最高为0.166 mg/kg, 干制黄蘑中总砷的平均含量最高为0.075 mg/kg。结论 本次调查抽取的干制食用菌中大部分样品的重金属含量达到国家标准要求, 应加强对超标干制食用菌的监测, 同时持续开展对干制食用菌中重金属的检测, 以确保食品安全。

英文摘要:

      Objective To understand the heavy metal content in dried edible fungus in Jilin province. Methods Seven kinds of dried edible fungi were randomly selected from the production and circulation fields in 10 regions of Jilin province. A total of 167 samples were collected, and the content of lead, cadmium, total arsenic and total mercury in the samples were determined. The results were evaluated according to GB 2762-2012 National food safety standard-Limits of contaminants in food. Results The total over-standard rate of heavy metals in 167 dried edible fungus was 3.6%. Among the 7 kinds of dried edible fungus, the cadmium content in the dried Armillaria mellea was highest with the average value of 0.166 mg/kg, and the average content of total arsenic in dried Sarcomyxa edulis was 0.075 mg/kg. Conclusion The heavy metal content of most dried edible fungus in this investigation meets the national standard. The monitoring of over-standard dried edible fungi should be strengthened, and the detection of heavy metals in dried edible fungi should be continuously carried out to ensure food safety.
