Device used for detecting veterinary drug residues in poultry meat on basis of fluorescence and Raman spectra

Abstract

The invention belongs to the technical field of food safety detection and particularly relates to a device used for detecting veterinary drug residues in poultry meat on the basis of fluorescence andRaman spectra. The device comprises a sample fluorescence spectrum acquisition unit, a sample Raman spectrum acquisition unit, a power supply and a computer. The sample fluorescence spectrum acquisition unit comprises a xenon lamp, an exciting single emitter, fluorescence emission fiber, a fiber probe, fluorescence receiving fiber, a fluorescence spectrometer, a controller, a computer and a powersupply; the sample Raman spectrum acquisition unit comprises a Raman laser, Raman emission fiber, a fiber probe, Raman receiving fiber, a Raman spectrometer, a controller, a computer and a power supply, the fiber probe is sequentially connected with an integrating sphere, a connecting rod and a sample injection disc, a shading plate is arranged above the sample injection disc, a slide rail 1 and aslide rail 2 are arranged on two sides, the lower side is sequentially connected with a rack, a gear and a stepping motor, and the power supply supplies power to each part. In the sampling process, multiple samples can be placed in the sample injection disc once, continuous acquisition of the samples is realized, and the detection efficiency can be improved. Besides, the device can acquire fluorescence and Raman spectrum information simultaneously and can obtain higher detection accuracy as compared with a detection device only using single fluorescence or Raman spectrum information.

Description

technical field [0001] The invention belongs to the technical field of food safety detection, and in particular relates to a detection device for veterinary drug residues in poultry meat based on fluorescence and Raman spectroscopy. Background technique [0002] In the poultry farming industry, antibiotics and hormonal veterinary drugs have played an active role in preventing and treating poultry diseases, improving feed conversion rate, and promoting poultry growth and development. However, unreasonable use of veterinary drugs can easily lead to excessive residues of veterinary drugs in poultry meat. If the poultry meat with excessive veterinary drug residues enters the market, it will cause potential hazards such as carcinogenicity, teratogenicity, mutagenicity, allergy, and bacterial drug resistance to the human body. Based on this, many countries and regions in the world have imposed strict limit requirements on veterinary drug residues in poultry meat. The conventiona...
