The present invention relates to oligonucleotide primers and probes for accurate quantification of fox source components. The invention also relates to a digital PCR detection method for quantitative detection of fox derived ingredients. The method includes using specific oligonucleotide primers and probes for single copy nuclear genes for fox source components. The invention also relates to a digital PCR detection kit for precise and quantitative detection of fox derived ingredients. The kit includes specific oligonucleotide primers and probes for digital PCR detection of fox derived ingredients. Specific oligonucleotide primers and probes of the invention also relates to the source components of a single copy of the housekeeping gene in the detection of fox source components and accurate quantitative gene copy application in number. The application of specific oligonucleotide primers and probes of the invention also relates to the source components of a single copy of the housekeeping gene in precise quantitative detection of fox source components in absolute mass fraction. The quantitative detection method and kit of the digital PCR can be used for the determination of the content of fox derived ingredients in fresh meat and processed meat products with a specific, sensitive and precise method.

技术介绍
肉及其制品营养丰富,蛋白质含量约为10%-20%,畜肉中含丰富的B族维生素,禽肉中不饱和脂肪酸含量较高,如人体必需的亚油酸,约占总脂肪含量的20%。全国范围内肉制品的产量和消费量持续升高,2013年我国成为全球肉类生产第一大国,年产量达8536万吨,伴随而来的是近年来肉制品的掺假掺杂事件频繁发生。2013年,我国部分地区开展了肉及其制品的掺假情况调查,结果显示有25.6%的样品与标识不符,肉制品掺假情况较明显,熟制牛肉和食用羊肉卷是肉类掺假高危品。同年,有新闻报道,山东济南沃尔玛超市出现熟牛肉、驴肉中掺杂狐狸肉事件。狐狸是不作为食用的肉类样品,常常未经过检验检疫就掺入到其他肉种中。以上肉制品掺假事件严重干扰了我国的肉业生产,不仅成为 ...
