Abstract

The invention discloses a method for detecting veterinary drug residues in fish meat, which comprises the following steps: (1) preparing a sample solution: taking and homogenizing fish meat, adding an acetonitrile aqueous solution containing formic acid, standing for 5-25 minutes, adding homogeneous protons, performing vortex oscillation for 20-40 minutes, centrifuging for 3-7 minutes, taking supernate, enabling the supernate to pass through a reversed-phase solid-phase extraction column, collecting effluent, blow-drying the effluent by N2 gas, adding an initial mobile phase, dissolving and filtering to obtain a test solution; and (2) detecting by adopting an ultra-high performance liquid chromatography-mass spectrometer. According to the method, through a specific sample pretreatment method and an instrument analysis method, veterinary drug residues cover mainstream veterinary drug types such as hormone and macrolide antibiotics and zeranol compounds, and the detection sample range is increased to bulk consumer fish species with complex matrixes such as turbots, mandarin fishes, snakeheaded fishes and grass carps; and the method is simple and rapid, low in cost, high in accuracy and good in stability.

Description

technical field

[0001] The invention specifically relates to a method for detecting veterinary drug residues in fish meat. Background technique

[0002] The main source of nutrients such as high-quality protein, fat and essential amino acids for human beings is one of the main food raw materials in people's three meals a day. With the continuous improvement of the living standards of Chinese residents, people's demand for fish consumption is also increasing. However, in the process of fish farming, production, transportation and sales, in order to prevent and control fish diseases, promote the rapid growth of fish and increase industrial income, there are phenomena of misuse or abuse of veterinary drugs. The excessive use of veterinary drugs not only directly affects food safety, but also indirectly affects the ecological environment and fishery trade. The safety of veterinary drugs in food has been highly valued by the government and the people. solved problem.
