食用菌中重金属微生物食品添加剂（GB7096-2014）和放射性污染物与CAC和欧美日韩标准比较研究

[Objective] To evaluate the control level of heavy metals and radioactive substances, microbial limit and food additives in edible fungus and break or cross technical trade barriers. [Methods] Comparative analysis GB 2762--2017 limit of pollutants in food, GB 2760--2014 Standard for the use of food additives，GB 29921-2021 limited number of pathogenic bacteria in prepackaged foods as cited by GB 7096-2014 edible fungi and their products, and GB 14882-1994 standard for concentration limit of radioactive substances in food with CAC, EU, USA, Japan, Korea standard on heavy metal, radioactive substance, pathogenic microorganisms and food additives in mushrooms and other similar edible fungi. [Results] Heavy metal control species in Chinese edible fungi and/or mushrooms（fresh）are more than CAC and Europe, Japan and Korea standard, the limit of same heavy metal in our country is wider than their standards; The limit of radioactive substances pollution is less than CAC and Europe, Japan and Korea standard; Microorganism species is more than CAC, Europe, America and Japan, less than Korean, the same microorganism species are same limits; Food additive used standard are difference between CAC, Europe, America and Japan, less than Korean, fresh or frozen edible fungi shall not use food additives in GB2760-2014. They are strict than CAC and Europe, America, Japan and South Korea. [Conclusion] Standards for the item and limit of heavy metal, radioactive pollution, pathogenic microorganism and food additives of edible fungi are quite different from the imported countries and CAC standards. Export edible fungi should comply with the requirements of the imported countries standard for ensuring the export safety and promoting the high-quality development of the edible fungus industry.
