| titleOfInvention | High-throughput detection method for 92 forbidden industrial dyes in food |
| abstract | The invention discloses a high-flux detection method for 92 forbidden industrial dyes in food, which is characterized by comprising the following specific steps: (1) based on a carrier-assisted liquid-liquid extraction technology, the method completes extraction and purification work of common 4 types of industrial dyes with greatly different physicochemical properties by one-time pretreatment, and totally 92 types of forbidden industrial dyes; (2) preparing a mixed standard solution composition and a matrix standard curve; (3) determining the concentration of 92 forbidden industrial dyes in a sample to be detected by using ultra-high performance liquid chromatography-full scanning high resolution mass spectrometer; the method has the advantages that the pretreatment and the instrument analysis process of the method are strong in compatibility of compounds with different physicochemical properties, high in detection efficiency and strong in operability, the detection limit can meet all tested target objects, and the detection cost is reduced. |
