Study on the Identification of Tainted Starch Noodles[J]. 2014,33(8):955-958.
采用气相色谱-质谱(GC-MS)和液相色谱-串联质谱(LC-MS/MS)技术,研究了墨汁粉条(假红薯粉条)及纯正红薯粉条中微量成分的差别。经GC-MS方法检测发现墨汁粉条中含有苯酚、六氢吡咯并[1,2a]吡嗪-1,4-二酮,用LC-MS/MS方法检测发现墨汁粉条中含有人工色素柠檬黄、日落黄和亮蓝,而纯正红薯粉条中不含以上物质。以该5种物质作为特征成分,建立了GC-MS和LC-MS/MS联合鉴别墨汁粉条的新方法。
Two methods,gas chromatography-mass spectrometry(GC-MS) and liquid chromatography-tandem mass spectrometry(LC-MS/MS) were proposed for the study on the trace components in tainted starch noodles(fake starch noodles) and noodles made from real sweet potato.Some impurities such as phenol and pyrrolo[1,2a]pyrazine-1,4-dione,hexahydro-six were detected by GC-MS,and tartrazine,sunset yellow and brilliant blue were found by LC-MS/MS,while such components would not exist in real sweet potato.The existence of these substances could be used to confirm weather starch noodles were tainted or not.
