摘要
以2-十二烷基环丁酮(2-DCB)为检测目标物,使用60Coγ射线在1-10kGy辐照剂量下对猪肉进行辐照,用气质联用仪(GC-MS)进行定量分析,显示2-DCB浓度与辐照剂量呈线性关系,从而计算出辐照加工猪肉盲样的辐照剂量～1.19kGy。对辐照后的猪肉进行微波加热,发现微波加热方式对2-DCB基本没有影响。
As unique radiolytic products formed in irradiated fat-containing food, alkylcyclobutanones （2-ACBs） can be used to determine history of irradiation and estimate absorbed doses. The cyclobutanone in this study was 2-dodecylcyclobutanone （2-DCB） determined by gas chromatogram with mass spectrum. Pork samples were irradiated to 1-10 kGy by ^60Co γ-rays. A linear relationship between 2-DCB concentration and dose was established. In addition, the irradiated pork samples were cooked with a microwave oven and 2-DCB was detected. The results showed that 2-DCB was stable after microwave cooking.
