动物源性食品中多种兽药残留检测的研究进展

随着人们生活水平的提高,食品的安全性也越来越受到广泛关注。目前,畜禽动物的食品交易频繁而广泛,与此同时也伴随着兽药残留等食品安全性问题,其兽药残留大多存在于这一类动物源性食品的生长以及加工过程中,具有残留水平低、种类多、基质效应复杂等特点。针对这些特点,国际上大多通过各种前处理技术减小基质效应的影响,采用液相色谱-质谱(liquid chromatography-mass spectrometry, LC-MS)等质谱联用技术来对食品中的超痕量浓度残留物进行分析及筛查。本文主要对兽药残留的前处理技术和检测技术进行了综述,以期为保障动物源性食品的质量安全提供参考。

Research progress on detection of various veterinary drug residues in animal-derived foods

With the improvement of people''s living standard, the safety of food has also received more and more attention. At present, the food transactions of livestock and poultry are frequent and extensive, and at the same time, food safety problems such as veterinary drug residues are accompanied. Most of the veterinary drug residues are present in the growth and processing of this kind of animal-derived food, generally with low residual amount, many types, complex matrix effects and so on. In response to these characteristics, most of pre-treatment techniques are developed to reduce the effects of matrix effects, and liquid chromatography-mass spectrometry (LC-MS) and other mass spectrometry techniques have been used to analyze and screen ultra-trace concentration residues in foods. This paper reviewed the pretreatment techniques and detection techniques of veterinary drug residues, in order provide references for ensuring the quality and safety of animal-derived food.
