摘要: 建立牛、羊、猪、鸡、鸭5种常见动物肉类成分的聚合酶链式反应(PCR)鉴别方法。分别使用牛、羊、猪、鸡、鸭的特异性引物对牛、羊、猪、鸡、鸭肉的总DNA进行扩增,获得494、716、611、259bp和350bp的DNA片段,通过限制性内切酶验证了该PCR扩增的特异性。使用上述引物对掺杂牛肉、猪肉、鸡肉和鸭肉的羊肉进行鉴别,结果表明,该方法的检出限可以达到1%以下。

Abstract: A new method was established to identify five species of meat such as beef, mutton, pork, chicken and duck through polymerase chain reaction (PCR). Using specific primers and total DNA from each species of meat as the template, fragments with sizes of 494, 716, 611, 259 bp and 350 bp were obtained, respectively. Our results were further confirmed through the digestion of restriction enzymes. In addition, mutton with 1% added beef, pork, chicken and duck was identified using the designed primers. The detection limit of this method was 1%. Quick and accurate identification of meat can be achieved using it.

Key words: polymerase chain reaction, meat identification, mixed meat, beef, mutton
