牛奶中农药残留前处理研究进展

Research progress of overview on sample pretreatment of pesticides residue in milk

由于牛奶在食物营养链中又处于较高级,所以其含有的农药残留量相对较高。随着人们对食品安全重视程度的提升,牛奶中含有的各种有害物质残留的检测方法受到了消费者的极大关注。牛奶中农药残留检测是一项关系食品安全的重要问题,而样品前处理是检测的关键步骤。本文综述了近年来牛奶中农药残留的提取,净化的前处理方法,对液液萃取,固相萃取,固相微萃取,基质分散固相萃取,凝胶渗透色谱,浊点萃取,QuEChERS等方法进行了详细阐述。文章综述了牛奶中农药残留前处理检测方法进展,旨在为进一步开展牛奶农残残留检测提供参考。

The level of pesticide residues in milk is relatively quite high as milk is close to the top of food chain. So the harmful substance in milk had attracted much attention of consumer. With the increase of public attention to food safety, detection of pesticide and veterinary drug residues in milk has become a hot topic of food safety in today’s China. Meanwhile, sample preparation is a very critical step in the determination process and it determines the analysis accuracy and precision. This article makes a brief summary of liquid-liquid ex-traction, solid phase extraction, solid phase microextraction, matrix solid-phasedispersion extraction, Gel Per-meation Chromatography, cloud point extraction, and QuEChERS. This article reviewed the new research progress of sample preparation of pesticide residues in milk, aimed to supply some reference to the further re-search in this area.
