【摘要】：非法食用色素在食品加工中的大量使用以及四环素类抗生素在畜禽和水生生物养殖过程中的大量使用对消费者的身体健康造成了严重的影响,因此建立一种能够对上述物质进行快速准确分析的方法是很有必要的。本论文选择了检出率较高的九种非法食用色素和四种四环素类抗生素作为研究对象,针对不同的样品和提取物质,采用不同的前处理方法,并采用液相色谱串联质谱仪进行分析,对所建立方法的线性和准确度进行验证实验,从而建立了九种非法食用色素和四种四环素类抗生素残留的液相色谱串联质谱法,表明九种非法食用色素的回收率为70.2%~99.8%,相对标准偏差为2.2~8.0%,四种四环素类抗生素的回收率为80.0%~94.5%,相对标准偏差为2.4~7.9%,测定结果满意。本论文研究的检测方法适用于食品及食用活动物中有毒有害物质的快速检测。
[Abstract]:The heavy use of illegal food pigments in food processing and the use of tetracycline antibiotics in livestock and aquatic breeding have had serious effects on the health of consumers. Therefore, it is necessary to establish a rapid and accurate method for the analysis of these substances. Nine kinds of illegal edible pigments and four tetracycline antibiotics with high detection rate were selected as the research objects. Different pretreatment methods were used for different samples and extracts. The linearity and accuracy of the established method were verified by using liquid chromatography tandem mass spectrometer. Nine kinds of illegal edible pigments and four tetracycline antibiotics residues were established by liquid chromatography-tandem mass spectrometry (LC-MS). The results showed that the recoveries of nine kinds of illegal edible pigments were 70.2 and 99.8, the relative standard deviations were 2.2 and 8.0, the recoveries of four tetracycline antibiotics were 80.00.94. 5 and the relative standard deviations were 2. 4 and 7. 9, respectively. The results were satisfactory. This method is suitable for rapid detection of toxic and harmful substances in food and living animals.
