Method for detecting veterinary drug residue of animal-derived product

Abstract

The invention belongs to the technical field of food safety detection, and discloses a method for detecting veterinary drug residue of an animal-derived product. The method comprises the following steps: analyzing an extracting solvent, an extracting method and a purifying technology suitable for a sample to be detected, and extracting and purifying components to be detected in the sample; separating 63 analytes under a liquid chromatography separation condition, and performing baseline separation on 6 groups of isomers; simultaneously detecting sulfonamides, sulfonamide synergists, quinolones, beta-receptor agonists, tetracyclines, macrolides, quinolines, nitroimidazoles, cephalosporins and penicillins, altogether 63 veterinary drugs in 10 categories, through selection and use of an MS / MSdetector, an ESI ion source, a schedul MRM mode, three-ion confirmation and an internal / external standard quantifying technology. The method provided by the invention is applied to detection of 10 categories, altogether 63 kinds, of veterinary drugs, such as sulfonamides in a daily animal product; through improvement on the working efficiency and reduction in the detection cost, a food safety emergency can be quickly handled, and social and economic benefits are brought.

Description

technical field [0001] The invention belongs to the technical field of food safety detection, and in particular relates to a detection method for detecting veterinary drug residues in animal-derived products. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] my country is a big country for animal-derived food. According to customs statistics, in 2013, my country's aquatic product exports reached 3.84 million tons and 19.4 billion US dollars, an increase of 4.2% and 7.2% year-on-year, and the export volume of aquatic products ranked No. 1 for 13 consecutive years. The export of aquatic products accounted for 22.4% of the total export of agricultural and sideline products in my country. As a large aquatic product breeding country, the country has successively issued policies to encourage the export of aquatic products. However, due to factors such as environmental pollution, disease spread, germplasm deg...
