| titleOfInvention | Method for rapidly detecting contents of 2-methylimidazole and 4-methylimidazole in caramel color |
| abstract | The invention relates to the technical field of analysis and detection, and provides a method for rapidly detecting the contents of 2-methylimidazole and 4-methylimidazole in caramel color. According to the method, water is used for dissolving caramel color, and then the methylimidazole and the water-soluble caramel color are quickly separated based on the characteristic that isobutyl chloroformate can be used for derivatizing methylimidazole in a water environment and the derivative is dissolved in n-hexane, and then the determination is carried out by using a gas chromatography-mass spectrometry method. The method has simple sample pretreatment, and the caramel can be directly subjected to derivatization without purification treatment after being dissolved in water for further detection and analysis. In the sample pretreatment process, the dosage of the organic solvent is only about 2mL, the sample pretreatment time is only about 10min, and the rapid detection of a large number of samples can be simultaneously carried out. |
