摘    要:为探索鸡蛋中三聚氰胺的既简单又能满足灵敏度的检测方法,将5.0 g蛋清样品经沸水浴变性,用10 g/L三氯乙酸溶液提取,再经Oasis-MCX SPE小柱的净化和浓缩后上机检测.结果表明:4个平行的平均回收率为86.5%,RSD值为3.88%,最低检出限为0.10 mg/kg.表明,该方法能较好地满足三聚氰胺分离、检测的需要.

关 键 词:高效液相法  鸡蛋  三聚氰胺

Abstract:More attentions came to melamine due to its renal toxicity.A method was developed to determinate melamine residue in eggs.5.0 g of egg white sample was denatured with boiled water bath and extracted with 10 g/L trichloracetic acid solution,then cleaned with Oasis-MCX SPE column.The average recoveries of 4 batches of samples were 86.5% and RSD were 3.88%.The detection limit of this method was 0.10 mg/kg.
Keywords:HPLC  chicken egg  melamine
