摘要
目的采用高效液相色谱–电感耦合等离子体质谱法测定贝类水产品中无机砷的含量,根据其无机砷含量水平进行食用安全性评价。方法随机采购自当地市场市售的4种贝类水产品,通过酸溶液浸泡提取,分离过滤后测定提取液中无机砷的含量。结果4种贝类水产品的平均无机砷含量分别为:波纹巴非蛤0.067~0.140 mg/kg、菲律宾帘蛤0.120~0.470 mg/kg、白蛤0.061~0.140 mg/kg、缢蛏0.056~0.190 mg/kg。其中菲律宾帘蛤的无机砷含量最高。结论2023年佛山市市售贝类水产中无机砷的含量未超过我国食品安全国家标准的限量定值0.5 mg/kg,常见的贝类水产品整体处于食用安全状态,但仍需对食用高风险贝类水产品保持谨慎态度,注意烹饪加工彻底,同时需要强化食品安全意识,加强对此类水产品的监督管理,开展食品安全知识宣传和健康教育。
Objective To determine the content of inorganic arsenic in shellfish and aquatic products by high performance liquid chromatography-inductively coupled plasma mass spectrometry,and to evaluate the food safety according to the content level of inorganic arsenic.Methods Four kinds of shellfish products were randomly purchased from local markets and extracted by soaking in acid solution.After separation and filtration,the content of inorganic arsenic in the extracted solution was determined.Results The average inorganic arsenic content of the 4 kinds of shellfish products were 0.067~0.140 mg/kg for Paphia undulata,0.120~0.470 mg/kg for clam Philippines,0.061~0.140 mg/kg for clam white,and 0.056~0.190 mg/kg for Sinonovacula constricta,respectively.The highest content of inorganic arsenic was found in Philippinarum clam.Conclusion The content of inorganic arsenic in shellfish products sold in Foshan City in 2023 does not exceed the limit value of 0.5 mg/kg of China’s national food safety standard.Common shellfish aquatic products are generally safe to eat.However,it is still necessary to be cautious about eating high-risk shellfish products and pay attention to thorough cooking and processing.At the same time,it is necessary to strengthen the awareness of food safety,strengthen the supervision and management of such aquatic products,and carry out food safety knowledge publicity and health education.
