    摘要:

    目的 建立一种肉制品中毛皮动物源性成分掺假快速检测技术。方法 构建狐狸、貉、水貂三种检测用阳性质粒分子,利用实时荧光定量PCR方法对其特异性、灵敏度和方法适用性等关键指标进行分析。结果 构建好的狐狸、貉、水貂阳性质粒分子特异性强、灵敏度高,检验灵敏度均可达到10-4 ng/μL,标准曲线扩增效率分别为94.451%、117.461%、114.709%,且相关系数(R2)均在0.995以上。在混合肉样品和市售肉制品中均可检测,三种成分的检测限均低至1%,具有较好的可行性及适用性。结论 本方法构建的三种阳性质粒分子可以满足实际工作中肉类掺假检测的需求。

    Abstract:

    Objective To establish a rapid detection method for adulteration of fur animal-derived components in meat products.Methods Three positive plasmids (fox, raccon dog and mink) for detection were constructed, and their specificity, sensitivity and applicability were analyzed by real-time quantitative PCR.Results The 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.Conclusion The three positive plasmids constructed by this method could meet the needs of meat adulteration detection in practical work.
