摘  要:
以大豆主要过敏蛋白P34基因为靶标,采用TaqMan探针实时荧光PCR方法建立食品过敏原大豆成分的检测方法。实验表明建立的检测方法具有特异性,灵敏度高,检测限为10mg/kg。通过对市售样品的检测,该方法适用于对常见食品种类的检测,但不适用于精加工油脂等精细加工产品的检测。

摘  要:
A real-time PCR method was established for detecting soybean DNA in food by using primers and probe corresponding to soybean immunodominant allergen P34.The method was specific for soybean and did not show any cross-reactivity with common food ingredients.The limit of detection was determined as 10mg/Kg.The PCR procedure is suitable for detecting soybean in food except refined products.
