用于貉源性成分数字PCR精准定量检测的引物探针及方法和试剂盒
本专利技术属于生物
,具体而言,本专利技术涉及用于貉源性成分定量检测的寡核苷酸引物和探针,用于测定貉源性成分的数字PCR检测方法,用于精准定量貉源性成分的数字PCR检测试剂盒以及貉源性成分的特异性寡核苷酸引物和探针在检测样品中貉源性成分中的应用。
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。而貉肉本身也是一种肉质鲜美高级滋补营养野味食品,细嫩鲜美、营养丰富、滋补身体,还可入药,其胆、睾丸是名贵中药材。有些不法商家将其他肉代替貉肉进行销售,或者将貉肉掺入其他肉中冒充牛羊肉。以上肉制品掺假事 ...
