中文摘要:

      目的 初步了解粮食加工品中玉米赤霉烯酮和呕吐毒素的污染情况。方法 对北京地区和网购的200批次样品进行随机抽检, 分别采用液相色谱法、免疫亲和层析净化高效液相色谱法对粮食加工品中的玉米赤霉烯酮和呕吐毒素进行了检测。结果 初步调查发现玉米碾磨加工品中的玉米赤霉烯酮和小麦粉中的呕吐毒素检出率较高, 分别达34%和74%; 散装样品中玉米赤霉烯酮含量不合格率和检出率明显高于预包装样品。结论 建议监管部门加强对散装玉米碾磨加工品和小麦粉等粮食加工品中毒素指标的监控力度和监测频次, 同时针对我国特殊敏感人群加快设定合理限值。

英文摘要:

      Objective To investigate the contamination of zearalenone and deoxynivalenol in processed food. Methods A random sampling of 200 batches of samples from Beijing and online shopping was carried out, and zearalenone and deoxynivalenol in food processed products were detected by liquid chromatography, immunoaffinity chromatography and high performance liquid chromatography. Results Preliminary investigation showed that the detection rates of zearalenone in corn milling products and deoxynivalenol in wheat flour were higher (34% and 74%, respectively). The disqualification rate and detection rate of zearalenone in bulk samples were significantly higher than those in prepackaged samples. Conclusion It is recommended that the regulatory authorities strengthen the monitoring and monitoring frequency of toxins in food processed products such as bulk corn milled products and wheat flour, and speed up the setting of reasonable limits for special sensitive populations in China.
