Popis: ObjectiveTo establish a rapid detection method for adulteration of fur animal-derived components in meat products.MethodsThree positive plasmids (fox, raccon dog and mink) for detection were constructed, and their specificity, sensitivity and applicability were analyzed by real-time quantitative PCR.ResultsThe constructed positive plasmid molecules of fox, raccoon dog and mink had high specificity and sensitivity, and the sensitivity could reach 10-4 ng/μL. The amplification efficiency of standard curves were 94.451%, 117.461% and 114.709%, respectively. And the correlation coefficient R2 was over 0.995. Three components could be detected in mixed meat samples as well as common meat products, the limits of detection were less than 1%, which had good feasibility and applicability.ConclusionThe three positive plasmids constructed by this method could meet the needs of meat adulteration detection in practical work.
