【摘要】 对乳中抗生素残留的2种微生物检测法进行了比较,确定2种方法对6种广谱-β内酰胺类抗生素的检测限,同时指出了国标TTC法对6种广谱抗生素均不能检出欧盟法典规定的MRL残留浓度,而AOAO纸片法对其检测限均在MRL浓度范围内,且符合欧盟药典确定的最大残留量限制。建议乳中抗生素残留检测过程中,采用特异性与灵敏度高、经济简便、检测限达到MRLs规定的AOAO纸片法作为国标TTC检测法的补充。更多还原

【Abstract】 Two microbial standard methods to detect β-lactam residues in milk were compared in this paper.The detection limits of two methods for six kinds of β-lactams were determined.The results showed that the TTC method could not detect the MRL antibiotic residual concentration regulated by EU,while the AOAC paper disk method could.The AOAC method was suggested to be a supplement of TTC method to determine residual β-lactams in milk because of its specificity,sensitivity,convenience and economy.The detection limit of AOAC method for the six β-lactams also measured up the MRLS regulation.更多还原
