Embodiment Construction

[0076] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0077] The present invention takes animal products such as shrimp, bullfrog legs, fish meat, and pig muscle as objects, and analyzes suitable extraction solvents, extraction methods, and purification techniques to extract and purify components to be measured in samples, so as to maximize extraction efficiency and eliminate measurement interference;

[0078] Using appropriate liquid chromatography separation conditions to separate 63 analytes, so that isomers can achieve baseline separation;

[0079] Select MS / MS detector, ESI ion source, scheduled MRM mode, triple ion confirmation, internal / external standard quantitative te...

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...
