| titleOfInvention | Rapid extraction, purification and detection method of Sudan red dye residue in food |
| abstract | The invention relates to a rapid extraction, purification and detection method of Sudan red dye residue in food, wherein the food is one of egg, pepper and chili oil, comprising the following steps: the egg sample or the pepper sample is mixed with acetonitrile-dichloromethane Liquid extraction, followed by strong cationic solid-phase extraction column purification, while the pepper oil sample was mixed with dichloromethane-n-hexane and directly purified on the column; ultrafast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS) detection. This method overcomes the problems of low recovery rate of Sudan Red III and Sudan Red IV and the problem that egg samples are easy to loosen and difficult to achieve effective solid-liquid separation, and has the advantages of simple steps and convenient operation; The final purified solution is tested for Sudan red content, which overcomes the shortcomings of the existing liquid chromatography method, such as poor sensitivity, low accuracy, and high false positive rate, so that the standard addition recovery rate of the four Sudan red dyes is 90.6 to 99.4%. The limit is 0.1~0.5μg/kg. |
