The invention discloses a method for detecting antiviral drug residues in milk and milk powder, and belongs to the technical field of drug residue detection.The method comprises the following steps of: S1, providing a to-be-detected milk sample, a to-be-detected milk powder sample, a milk blank sample, a milk powder blank sample and acidified acetonitrile; S2, homogenizing and extracting target compounds in the to-be-detected milk sample and the to-be-detected milk powder sample; S3, respectively carrying out purification treatment on the extracting solution I and the extracting solution II; S4, carrying out gradient elution treatment; S5, carrying out detection treatment by using an ultra-high performance liquid chromatography-tandem mass spectrometer; S6, detecting and calculating the standard curves, correlation coefficients, detection limits and quantitation limits of the five antiviral drugs; and S7, calculating the adding standard recovery rate and the relative standard deviation RSD of the five antiviral drugs. The antiviral drug residue detection method provided by the invention has the advantages of simple operation, high sensitivity and good selectivity, and is suitable for rapid detection of antiviral drug residues in milk and milk powder.
Description
technical field [0001] The invention belongs to the technical field of drug residue detection, and in particular relates to a method for detecting antiviral drug residues in milk and milk powder. Background technique [0002] In order to ensure the safety of dairy products, it is necessary to detect and analyze the antiviral drug residues in milk and milk powder, and evaluate whether the indicators of milk and milk powder meet the food health standards through testing. The current drug residue detection method is inconvenient to operate, low in sensitivity, poor in selectivity and applicability when detecting antiviral drugs in milk and milk powder, and cannot perform well on antiviral drug residues in milk and milk powder. Separation, identification and rapid detection. Contents of the invention [0003] The object of the present invention is to provide a method for detecting antiviral drug residues in milk and milk powder, so as to solve the problems raised in the above...
