中文摘要:

      目的 调查云南省常见新鲜野生食用菌中硒含量水平。方法 收集云南省9个州市常见新鲜野生食用菌共计26个品种189件, 按照GB 5009.93-2017 《食品安全国家标准 食品中硒的测定》中原子荧光光谱法测定所采集的新鲜野生食用菌中的硒含量。结果 189件新鲜野生食用菌中有188件样品中检出硒, 检出率为99.5%, 硒含量范围为0.5~2670 μg/100 g, 平均值为126.0 μg/100 g, 中位值为35.0 μg/100 g, 其中硒含量最高的是昆明的干巴菌, 为2670 μg/100 g。结论 本研究为云南省常见新鲜野生食用菌中硒含量评价提供基础数据。

      Objective To investigate the level of selenium in common fresh wild edible fungi in Yunnan province. Methods A total of 189 pieces of 26 varieties of common fresh wild edible fungi in 9 prefecture-level cities of Yunnan province were collected, and the selenium content of collected fresh wild edible fungi was determined by atomic fluorescence spectrometry according to GB 5009.93-2017 National food safety standard- Determination of selenium in foods. Results Selenium was detected in 188 samples of 189 fresh wild edible fungi, the detection rate was 99.5%, the selenium content range was 0.5~2670 μg/100 g, and the average value was 126.0 μg/100 g. The median value was 35.0 μg/100 g, the highest selenium content was Kunming's dried bacteria, which was 2670 μg/100 g. Conclusion This study provides basic data for the evaluation of selenium content in common fresh wild edible fungi in Yunnan province.
